+title: Writing a New Post
+author: cotes
+date: 2019-08-08 14:10:00 +0800
+categories: [Blogging, Tutorial]
+tags: [writing]
+render_with_liquid: false
+---
+
+This tutorial will guide you how to write a post in the _Chirpy_ template, and it's worth reading even if you've used Jekyll before, as many features require specific variables to be set.
+
+## Naming and Path
+
+Create a new file named `YYYY-MM-DD-TITLE.EXTENSION`{: .filepath} and put it in the `_posts`{: .filepath} of the root directory. Please note that the `EXTENSION`{: .filepath} must be one of `md`{: .filepath} and `markdown`{: .filepath}. If you want to save time of creating files, please consider using the plugin [`Jekyll-Compose`](https://github.com/jekyll/jekyll-compose) to accomplish this.
+
+## Front Matter
+
+Basically, you need to fill the [Front Matter](https://jekyllrb.com/docs/front-matter/) as below at the top of the post:
+
+```yaml
+---
+title: TITLE
+date: YYYY-MM-DD HH:MM:SS +/-TTTT
+categories: [TOP_CATEGORIE, SUB_CATEGORIE]
+tags: [TAG]     # TAG names should always be lowercase
+---
+```
+
+> The posts' _layout_ has been set to `post` by default, so there is no need to add the variable _layout_ in the Front Matter block.
+{: .prompt-tip }
+
+### Timezone of Date
+
+In order to accurately record the release date of a post, you should not only set up the `timezone` of `_config.yml`{: .filepath} but also provide the post's timezone in variable `date` of its Front Matter block. Format: `+/-TTTT`, e.g. `+0800`.
+
+### Categories and Tags
+
+The `categories` of each post are designed to contain up to two elements, and the number of elements in `tags` can be zero to infinity. For instance:
+
+```yaml
+---
+categories: [Animal, Insect]
+tags: [bee]
+---
+```
+
+### Author Information
+
+The author information of the post usually does not need to be filled in the _Front Matter_ , they will be obtained from variables `social.name` and the first entry of `social.links` of the configuration file by default. But you can also override it as follows:
+
+Adding author information in `_data/authors.yml` (If your website doesn't have this file, don't hesitate to create one).
+
+```yaml
+<author_id>:
+  name: <full name>
+  twitter: <twitter_of_author>
+  url: <homepage_of_author>
+```
+{: file="_data/authors.yml" }
+
+And then use `author` to specify a single entry or `authors` to specify multiple entries:
+
+```yaml
+---
+author: <author_id>                     # for single entry
+# or
+authors: [<author1_id>, <author2_id>]   # for multiple entries
+---
+```
+
+Having said that, the key `author` can also identify multiple entries.
+
+> The benefit of reading the author information from the file `_data/authors.yml`{: .filepath } is that the page will have the meta tag `twitter:creator`, which enriches the [Twitter Cards](https://developer.twitter.com/en/docs/twitter-for-websites/cards/guides/getting-started#card-and-content-attribution) and is good for SEO.
+{: .prompt-info }
+
+### Post Description
+
+By default, the first words of the post are used to display on the home page for a list of posts, in the _Further Reading_ section, and in the XML of the RSS feed. If you don't want to display the auto-generated description for the post, you can customize it using the `description` field in the _Front Matter_ as follows:
+
+```yaml
+---
+description: Short summary of the post.
+---
+```
+
+Additionally, the `description` text will also be displayed under the post title on the post's page.
+
+## Table of Contents
+
+By default, the **T**able **o**f **C**ontents (TOC) is displayed on the right panel of the post. If you want to turn it off globally, go to `_config.yml`{: .filepath} and set the value of variable `toc` to `false`. If you want to turn off TOC for a specific post, add the following to the post's [Front Matter](https://jekyllrb.com/docs/front-matter/):
+
+```yaml
+---
+toc: false
+---
+```
+
+## Comments
+
+The global switch of comments is defined by variable `comments.active` in the file `_config.yml`{: .filepath}. After selecting a comment system for this variable, comments will be turned on for all posts.
+
+If you want to close the comment for a specific post, add the following to the **Front Matter** of the post:
+
+```yaml
+---
+comments: false
+---
+```
+
+## Mathematics
+
+We use [**MathJax**][mathjax] to generate mathematics. For website performance reasons, the mathematical feature won't be loaded by default. But it can be enabled by:
+
+[mathjax]: https://www.mathjax.org/
+
+```yaml
+---
+math: true
+---
+```
+
+After enabling the mathematical feature, you can add math equations with the following syntax:
+
+- **Block math** should be added with `$$ math $$` with **mandatory** blank lines before and after `$$`
+  - **Inserting equation numbering** should be added with `$$\begin{equation} math \end{equation}$$`
+  - **Referencing equation numbering** should be done with `\label{eq:label_name}` in the equation block and `\eqref{eq:label_name}` inline with text (see example below)
+- **Inline math** (in lines) should be added with `$$ math $$` without any blank line before or after `$$`
+- **Inline math** (in lists) should be added with `\$$ math $$`
+
+```markdown
+<!-- Block math, keep all blank lines -->
+
+$$
+LaTeX_math_expression
+$$
+
+<!-- Equation numbering, keep all blank lines  -->
+
+$$
+\begin{equation}
+  LaTeX_math_expression
+  \label{eq:label_name}
+\end{equation}
+$$
+
+Can be referenced as \eqref{eq:label_name}.
+
+<!-- Inline math in lines, NO blank lines -->
+
+"Lorem ipsum dolor sit amet, $$ LaTeX_math_expression $$ consectetur adipiscing elit."
+
+<!-- Inline math in lists, escape the first `$` -->
+
+1. \$$ LaTeX_math_expression $$
+2. \$$ LaTeX_math_expression $$
+3. \$$ LaTeX_math_expression $$
+```
+
+> Starting with `v7.0.0`, configuration options for **MathJax** have been moved to file `assets/js/data/mathjax.js`{: .filepath }, and you can change the options as needed, such as adding [extensions][mathjax-exts].  
+> If you are building the site via `chirpy-starter`, copy that file from the gem installation directory (check with command `bundle info --path jekyll-theme-chirpy`) to the same directory in your repository.
+{: .prompt-tip }
+
+[mathjax-exts]: https://docs.mathjax.org/en/latest/input/tex/extensions/index.html
+
+## Mermaid
+
+[**Mermaid**](https://github.com/mermaid-js/mermaid) is a great diagram generation tool. To enable it on your post, add the following to the YAML block:
+
+```yaml
+---
+mermaid: true
+---
+```
+
+Then you can use it like other markdown languages: surround the graph code with ```` ```mermaid ```` and ```` ``` ````.
+
+## Images
+
+### Caption
+
+Add italics to the next line of an image, then it will become the caption and appear at the bottom of the image:
+
+```markdown
+![img-description](/path/to/image)
+_Image Caption_
+```
+{: .nolineno}
+
+### Size
+
+In order to prevent the page content layout from shifting when the image is loaded, we should set the width and height for each image.
+
+```markdown
+![Desktop View](/assets/img/sample/mockup.png){: width="700" height="400" }
+```
+{: .nolineno}
+
+> For an SVG, you have to at least specify its _width_, otherwise it won't be rendered.
+{: .prompt-info }
+
+Starting from _Chirpy v5.0.0_, `height` and `width` support abbreviations (`height` → `h`, `width` → `w`). The following example has the same effect as the above:
+
+```markdown
+![Desktop View](/assets/img/sample/mockup.png){: w="700" h="400" }
+```
+{: .nolineno}
+
+### Position
+
+By default, the image is centered, but you can specify the position by using one of the classes `normal`, `left`, and `right`.
+
+> Once the position is specified, the image caption should not be added.
+{: .prompt-warning }
+
+- **Normal position**
+
+  Image will be left aligned in below sample:
+
+  ```markdown
+  ![Desktop View](/assets/img/sample/mockup.png){: .normal }
+  ```
+  {: .nolineno}
+
+- **Float to the left**
+
+  ```markdown
+  ![Desktop View](/assets/img/sample/mockup.png){: .left }
+  ```
+  {: .nolineno}
+
+- **Float to the right**
+
+  ```markdown
+  ![Desktop View](/assets/img/sample/mockup.png){: .right }
+  ```
+  {: .nolineno}
+
+### Dark/Light mode
+
+You can make images follow theme preferences in dark/light mode. This requires you to prepare two images, one for dark mode and one for light mode, and then assign them a specific class (`dark` or `light`):
+
+```markdown
+![Light mode only](/path/to/light-mode.png){: .light }
+![Dark mode only](/path/to/dark-mode.png){: .dark }
+```
+
+### Shadow
+
+The screenshots of the program window can be considered to show the shadow effect:
+
+```markdown
+![Desktop View](/assets/img/sample/mockup.png){: .shadow }
+```
+{: .nolineno}
+
+### CDN URL
+
+If you host the media resources on the CDN, you can save the time of repeatedly writing the CDN URL by assigning the variable `cdn` of `_config.yml`{: .filepath} file:
+
+```yaml
+cdn: https://cdn.com
+```
+{: file='_config.yml' .nolineno}
+
+Once `cdn` is assigned, the CDN URL will be added to the path of all media resources (site avatar, posts' images, audio and video files) starting with `/`.
+
+For instance, when using images:
+
+```markdown
+![The flower](/path/to/flower.png)
+```
+{: .nolineno}
+
+The parsing result will automatically add the CDN prefix `https://cdn.com` before the image path:
+
+```html
+<img src="https://cdn.com/path/to/flower.png" alt="The flower" />
+```
+{: .nolineno }
+
+### Media Subpath
+
+When a post contains many images, it will be a time-consuming task to repeatedly define the path of the media resources. To solve this, we can define this path in the YAML block of the post:
+
+```yml
+---
+media_subpath: /img/path/
+---
+```
+
+And then, the image source of Markdown can write the file name directly:
+
+```md
+![The flower](flower.png)
+```
+{: .nolineno }
+
+The output will be:
+
+```html
+<img src="/img/path/flower.png" alt="The flower" />
+```
+{: .nolineno }
+
+### Preview Image
+
+If you want to add an image at the top of the post, please provide an image with a resolution of `1200 x 630`. Please note that if the image aspect ratio does not meet `1.91 : 1`, the image will be scaled and cropped.
+
+Knowing these prerequisites, you can start setting the image's attribute:
+
+```yaml
+---
+image:
+  path: /path/to/image
+  alt: image alternative text
+---
+```
+
+Note that the [`media_subpath`](#media-subpath) can also be passed to the preview image, that is, when it has been set, the attribute `path` only needs the image file name.
+
+For simple use, you can also just use `image` to define the path.
+
+```yml
+---
+image: /path/to/image
+---
+```
+
+### LQIP
+
+For preview images:
+
+```yaml
+---
+image:
+  lqip: /path/to/lqip-file # or base64 URI
+---
+```
+
+> You can observe LQIP in the preview image of post \"[Text and Typography](../text-and-typography/)\".
+
+For normal images:
+
+```markdown
+![Image description](/path/to/image){: lqip="/path/to/lqip-file" }
+```
+{: .nolineno }
+
+## Pinned Posts
+
+You can pin one or more posts to the top of the home page, and the fixed posts are sorted in reverse order according to their release date. Enable by:
+
+```yaml
+---
+pin: true
+---
+```
+
+## Prompts
+
+There are several types of prompts: `tip`, `info`, `warning`, and `danger`. They can be generated by adding the class `prompt-{type}` to the blockquote. For example, define a prompt of type `info` as follows:
+
+```md
+> Example line for prompt.
+{: .prompt-info }
+```
+{: .nolineno }
+
+## Syntax
+
+### Inline Code
+
+```md
+`inline code part`
+```
+{: .nolineno }
+
+### Filepath Hightlight
+
+```md
+`/path/to/a/file.extend`{: .filepath}
+```
+{: .nolineno }
+
+### Code Block
+
+Markdown symbols ```` ``` ```` can easily create a code block as follows:
+
+````md
+```
+This is a plaintext code snippet.
+```
+````
+
+#### Specifying Language
+
+Using ```` ```{language} ```` you will get a code block with syntax highlight:
+
+````markdown
+```yaml
+key: value
+```
+````
+
+> The Jekyll tag `{% highlight %}` is not compatible with this theme.
+{: .prompt-danger }
+
+#### Line Number
+
+By default, all languages except `plaintext`, `console`, and `terminal` will display line numbers. When you want to hide the line number of a code block, add the class `nolineno` to it:
+
+````markdown
+```shell
+echo 'No more line numbers!'
+```
+{: .nolineno }
+````
+
+#### Specifying the Filename
+
+You may have noticed that the code language will be displayed at the top of the code block. If you want to replace it with the file name, you can add the attribute `file` to achieve this:
+
+````markdown
+```shell
+# content
+```
+{: file="path/to/file" }
+````
+
+#### Liquid Codes
+
+If you want to display the **Liquid** snippet, surround the liquid code with `{% raw %}` and `{% endraw %}`:
+
+````markdown
+{% raw %}
+```liquid
+{% if product.title contains 'Pack' %}
+  This product's title contains the word Pack.
+{% endif %}
+```
+{% endraw %}
+````
+
+Or adding `render_with_liquid: false` (Requires Jekyll 4.0 or higher) to the post's YAML block.
+
+## Videos
+
+### Video Sharing Platform
+
+You can embed a video with the following syntax:
+
+```liquid
+{% include embed/{Platform}.html id='{ID}' %}
+```
+
+Where `Platform` is the lowercase of the platform name, and `ID` is the video ID.
+
+The following table shows how to get the two parameters we need in a given video URL, and you can also know the currently supported video platforms.
+
+| Video URL                                                                                          | Platform   | ID             |
+| -------------------------------------------------------------------------------------------------- | ---------- | :------------- |
+| [https://www.**youtube**.com/watch?v=**H-B46URT4mg**](https://www.youtube.com/watch?v=H-B46URT4mg) | `youtube`  | `H-B46URT4mg`  |
+| [https://www.**twitch**.tv/videos/**1634779211**](https://www.twitch.tv/videos/1634779211)         | `twitch`   | `1634779211`   |
+| [https://www.**bilibili**.com/video/**BV1Q44y1B7Wf**](https://www.bilibili.com/video/BV1Q44y1B7Wf) | `bilibili` | `BV1Q44y1B7Wf` |
+
+### Video File
+
+If you want to embed a video file directly, use the following syntax:
+
+```liquid
+{% include embed/video.html src='{URL}' %}
+```
+
+Where `URL` is an URL to a video file e.g. `/assets/img/sample/video.mp4`.
+
+You can also specify additional attributes for the embedded video file. Here is a full list of attributes allowed.
+
+- `poster='/path/to/poster.png'` - poster image for a video that is shown while video is downloading
+- `title='Text'` - title for a video that appears below the video and looks same as for images
+- `autoplay=true` - video automatically begins to play back as soon as it can
+- `loop=true` - automatically seek back to the start upon reaching the end of the video
+- `muted=true` - audio will be initially silenced
+- `types` - specify the extensions of additional video formats separated by `|`. Ensure these files exist in the same directory as your primary video file.
+
+Consider an example utilizing all of the above:
+
+```liquid
+{%
+  include embed/video.html
+  src='/path/to/video/video.mp4'
+  types='ogg|mov'
+  poster='poster.png'
+  title='Demo video'
+  autoplay=true
+  loop=true
+  muted=true
+%}
+```
+
+> It's not recommended to host video files in `assets` folder as they cannot be cached by PWA and may cause issues.
+> Instead, use CDN to host video files. Alternatively, use a separate folder that is excluded from PWA (see `pwa.deny_paths` setting in `_config.yml`).
+{: .prompt-warning }
+
+## Audios
+
+### Audio File
+
+If you want to embed an audio file directly, use the following syntax:
+
+```liquid
+{% include embed/audio.html src='{URL}' %}
+```
+
+Where `URL` is an URL to an audio file e.g. `/assets/img/sample/audio.mp3`.
+
+You can also specify additional attributes for the embedded audio file. Here is a full list of attributes allowed.
+
+- `title='Text'` - title for an audio that appears below the audio and looks same as for images
+- `types` - specify the extensions of additional audio formats separated by `|`. Ensure these files exist in the same directory as your primary audio file.
+
+Consider an example utilizing all of the above:
+
+```liquid
+{%
+  include embed/audio.html
+  src='/path/to/audio/audio.mp3'
+  types='ogg|wav|aac'
+  title='Demo audio'
+%}
+```
+
+> It's not recommended to host audio files in `assets` folder as they cannot be cached by PWA and may cause issues.
+> Instead, use CDN to host audio files. Alternatively, use a separate folder that is excluded from PWA (see `pwa.deny_paths` setting in `_config.yml`).

+title: Getting Started
+description: >-
+  Get started with Chirpy basics in this comprehensive overview.
+  You will learn how to install, configure, and use your first Chirpy-based website, as well as deploy it to a web server.

+---
+
+## Prerequisites
+
+Follow the instructions in the [Jekyll Docs](https://jekyllrb.com/docs/installation/) to complete the installation of the basic environment. [Git](https://git-scm.com/) also needs to be installed.
+
+## Installation
+
+### Creating a New Site
+
+There are two ways to create a new repository for this theme:
+
+- [**Using the Chirpy Starter**](#option-1-using-the-chirpy-starter) — Easy to upgrade, isolates irrelevant project files so you can focus on writing.
+- [**GitHub Fork**](#option-2-github-fork) — Convenient for custom development, but difficult to upgrade. Unless you are familiar with Jekyll and are determined to tweak or contribute to this project, this approach is not recommended.
+
+#### Option 1. Using the Chirpy Starter
+
+Sign in to GitHub and browse to [**Chirpy Starter**][starter], click the button <kbd>Use this template</kbd> > <kbd>Create a new repository</kbd>, and name the new repository `USERNAME.github.io`, where `USERNAME` represents your GitHub username.
+
+#### Option 2. GitHub Fork
+
+Sign in to GitHub to [fork **Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/fork), and then rename it to `USERNAME.github.io` (`USERNAME` means your username).
+
+Next, clone the repository to your local machine, make sure it has [Node.js][nodejs] installed, then go to the root directory of the repo and run the following command:
+
+```console
+$ bash tools/init
+```
+
+> If you don't want to deploy your site on GitHub Pages, append option `--no-gh` at the end of the above command.
+{: .prompt-info }
+
+The above command will:
+
+1. Check out the code to the [latest tag][latest-tag] (to ensure the stability of your site: as the code for the default branch is under development).
+2. Remove non-essential sample files and take care of GitHub-related files.
+3. Build CSS/JS assets files and then make them tracked by Git.
+4. Automatically create a new commit to save the changes above.
+
+### Installing Dependencies
+
+Before running local server for the first time, go to the root directory of your site and run:
+
+```console
+$ bundle
+```
+
+## Usage
+
+### Configuration
+
+Update the variables of `_config.yml`{: .filepath} as needed. Some of them are typical options:
+
+- `url`
+- `avatar`
+- `timezone`
+- `lang`
+
+### Social Contact Options
+
+Social contact options are displayed at the bottom of the sidebar. You can turn on/off the specified contacts in file `_data/contact.yml`{: .filepath }.
+
+### Customizing Stylesheet
+
+If you need to customize the stylesheet, copy the theme's `assets/css/jekyll-theme-chirpy.scss`{: .filepath} to the same path on your Jekyll site, and then add the custom style at the end of it.
+
+Starting with version `6.2.0`, if you want to overwrite the SASS variables defined in `_sass/addon/variables.scss`{: .filepath}, copy the main sass file `_sass/main.scss`{: .filepath} into the `_sass`{: .filepath} directory in your site's source, then create a new file `_sass/variables-hook.scss`{: .filepath} and assign new value.
+
+### Customing Static Assets
+
+Static assets configuration was introduced in version `5.1.0`. The CDN of the static assets is defined by file `_data/origin/cors.yml`{: .filepath }, and you can replace some of them according to the network conditions in the region where your website is published.
+
+Also, if you'd like to self-host the static assets, please refer to the [_chirpy-static-assets_](https://github.com/cotes2020/chirpy-static-assets#readme).
+
+### Running Local Server
+
+You may want to preview the site contents before publishing, so just run it by:
+
+```console
+$ bundle exec jekyll s
+```
+
+After a few seconds, the local service will be published at _<http://127.0.0.1:4000>_.
+
+## Deployment
+
+Before the deployment begins, check out the file `_config.yml`{: .filepath} and make sure the `url` is configured correctly. Furthermore, if you prefer the [**project site**](https://help.github.com/en/github/working-with-github-pages/about-github-pages#types-of-github-pages-sites) and don't use a custom domain, or you want to visit your website with a base URL on a web server other than **GitHub Pages**, remember to change the `baseurl` to your project name that starts with a slash, e.g, `/project-name`.
+
+Now you can choose _ONE_ of the following methods to deploy your Jekyll site.
+
+### Deploy by Using GitHub Actions
+
+There are a few things to get ready for.
+
+- If you're on the GitHub Free plan, keep your site repository public.
+- If you have committed `Gemfile.lock`{: .filepath} to the repository, and your local machine is not running Linux, go to the root of your site and update the platform list of the lock-file:
+
+  ```console
+  $ bundle lock --add-platform x86_64-linux
+  ```
+
+Next, configure the _Pages_ service.
+
+1. Browse to your repository on GitHub. Select the tab _Settings_, then click _Pages_ in the left navigation bar. Then, in the **Source** section (under _Build and deployment_), select [**GitHub Actions**][pages-workflow-src] from the dropdown menu.  
+![Build source](pages-source-light.png){: .light .border .normal w='375' h='140' }
+![Build source](pages-source-dark.png){: .dark .normal w='375' h='140' }
+
+2. Push any commits to GitHub to trigger the _Actions_ workflow. In the _Actions_ tab of your repository, you should see the workflow _Build and Deploy_ running. Once the build is complete and successful, the site will be deployed automatically.
+
+At this point, you can go to the URL indicated by GitHub to access your site.
+
+### Manually Build and Deploy
+
+On self-hosted servers, you cannot enjoy the convenience of **GitHub Actions**. Therefore, you should build the site on your local machine and then upload the site files to the server.
+
+Go to the root of the source project, and build your site as follows:
+
+```console
+$ JEKYLL_ENV=production bundle exec jekyll b
+```
+
+Unless you specified the output path, the generated site files will be placed in folder `_site`{: .filepath} of the project's root directory. Now you should upload those files to the target server.

+title: Customize the Favicon
+author: cotes
+date: 2019-08-11 00:34:00 +0800
+categories: [Blogging, Tutorial]
+tags: [favicon]
+---
+
+The [favicons](https://www.favicon-generator.org/about/) of [**Chirpy**](https://github.com/cotes2020/jekyll-theme-chirpy/) are placed in the directory `assets/img/favicons/`{: .filepath}. You may want to replace them with your own. The following sections will guide you to create and replace the default favicons.
+
+## Generate the favicon
+
+Prepare a square image (PNG, JPG, or SVG) with a size of 512x512 or more, and then go to the online tool [**Real Favicon Generator**](https://realfavicongenerator.net/) and click the button <kbd>Select your Favicon image</kbd> to upload your image file.
+
+In the next step, the webpage will show all usage scenarios. You can keep the default options, scroll to the bottom of the page, and click the button <kbd>Generate your Favicons and HTML code</kbd> to generate the favicon.
+
+## Download & Replace
+
+Download the generated package, unzip and delete the following two from the extracted files:
+
+- `browserconfig.xml`{: .filepath}
+- `site.webmanifest`{: .filepath}
+
+And then copy the remaining image files (`.PNG`{: .filepath} and `.ICO`{: .filepath}) to cover the original files in the directory `assets/img/favicons/`{: .filepath} of your Jekyll site. If your Jekyll site doesn't have this directory yet, just create one.
+
+The following table will help you understand the changes to the favicon files:
+
+| File(s)             | From Online Tool                  | From Chirpy |
+|---------------------|:---------------------------------:|:-----------:|
+| `*.PNG`             | ✓                                 | ✗           |
+| `*.ICO`             | ✓                                 | ✗           |
+
+<!-- markdownlint-disable-next-line -->
+>  ✓ means keep, ✗ means delete.
+{: .prompt-info }
+
+The next time you build the site, the favicon will be replaced with a customized edition.

+This has to be the first time I've seen a product on Jaycar be cheaper than, well, literally anywhere else.

+
+Can't find anything below $20 on Amazon. Although, to be fair the Jaycar one does look like an older model, so maybe paying the ~$2 difference for the newer ones will be worth it anyways.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at `cotes.chung@gmail.com`. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at <https://www.contributor-covenant.org/version/1/4/code-of-conduct.html>

+# Contributing Guidelines
+
+_First of all, thank you for considering contributing to this project_ ! :tada:
+
+There are many ways to contribute, from writing tutorials or blog posts, improving the documentation, submitting bug
+reports and feature requests, or writing code that can be incorporated into the project. In order to make a good
+experience for both contributors and maintainers, please start with the "[General Rules](#general-rules)"
+before taking further action.
+
+## Table of Contents
+
+- [General Rules](#general-rules)
+- [Questions and Requests for Help](#questions-and-requests-for-help)
+- [Reporting a Bug](#reporting-a-bug)
+- [Suggesting a New Feature](#suggesting-a-new-feature)
+- [Contributing Code/Documentation](#contributing-codedocumentation)
+- [Helpful Resources](#helpful-resources)
+
+## General Rules
+
+All types of contributions (_pull requests_, _issues_, and _discussions_) should follow these rules:
+
+- You should read through the [Wiki][wiki] to understand the project features and how to use it properly. This is to
+respect the time of the project's developers and
+maintainers and to save their energy for other problems that really need to be resolved.
+
+- Use the [latest release version][latest-ver]. If your contribution involves code/documentation changes, update to the
+latest version of the default (`master`) branch.
+
+- Avoid making duplicate contributions by searching for existing [issues][issues] / [discussions][discus] /
+[pull requests][pr], but don't leave any unhelpful comments such as "I have the same problem". Prefer using
+[reactions][gh-reactions] if you simply want to "+1" an existing issue.
+
+- DO NOT email or tweet the
+project developers and maintainers directly, everything about the project should be left on GitHub.
+
+**Tip**: If you are new to the open-source community, then please read through
+"[How To Ask Questions The Smart Way][ext-reading]" before contributing.
+
+## Questions and Requests for Help
+
+We expect every reasonable question you ask to be answered appropriately. If you want a quick and timely response,
+please ask questions at [Jekyll Talk][jekyll-talk] and [StackOverflow][stack-overflow], where there are tons of
+enthusiastic geeks who will positively answer your challenging questions.
+
+If you can't get an answer in any of the above ways, then create a new [discussion][discus]. As long as it is not a
+duplicate and [RTFM][rtfm] / [STFW][stfw] issue, we will respond as soon as possible.
+
+## Reporting a Bug
+
+A great way to contribute to the project is to send a detailed issue when you encounter a problem. We always appreciate
+a well-written, thorough bug report.
+
+1. Please figure out why the bug occurred, or locate the module in the project that caused this bug. Otherwise, there is
+a high probability that you are using/setting it incorrectly.
+
+2. If the issue is caused by you modifying the project code or some configuration of Jekyll, then please DO NOT
+report such "bugs".
+Chirpy is an open-source project, but that doesn't mean we will maintain other specific forks (such as yours).
+You can learn about Jekyll and modern Web development to solve problems caused by custom modifications.
+
+3. Make good use of your browser's incognito mode to troubleshoot if the problem is caused by caching.
+
+4. As a last option, you can create a new [Bug Report][bug-report] following the template to describe the details.
+If possible, providing a demo that reproduces the error will help us troubleshoot faster.
+
+## Suggesting a New Feature
+
+Feature requests are welcome! While we will consider all requests, we cannot guarantee your request will be accepted.  
+We want to avoid chaos in the UI design and therefore do not accept requests for changes like color schemes,
+fontfamilies, typography, and so on. We want to avoid [feature creep][feat-creep] and focus only on the core features.
+If accepted, we cannot make any commitments regarding the timeline for implementation and release. However, you are
+welcome to submit a pull request to help!
+
+## Contributing Code/Documentation
+
+If your request is about an enhancement, it is recommended to first submit a
+[Feature Request][feat-request] to discuss whether your idea fits the project.
+See also: "[Suggesting a New Feature](#suggesting-a-new-feature)". Other than that, you can start the PR process.
+
+1. Fork this project on GitHub and clone your repository locally.
+2. Setting up the [development & test environments][dev-env].
+3. Creating a new branch from the default branch and give it a descriptive name (e.g. `add-a-new-feat` or `fix-a-bug`).
+When development is complete, create a [Conventional Commit][cc] with Git.
+4. Submitting a [Pull Request][gh-pr].
