+# Money manager
+
+## I'm sick of using excel!
+
+Personal money dashboard I made for myself. I will add more features when I need to, for example a journalling system or location server. I also anticipate adding a proper frontend to this app, to get over Django's admin interface limitations.
+
+It's not the greatest code, since it tries to extend the django admin interface, which isn't designed for adding all of these features. For example, I want to make the charts show data from two tables, which required janking it in a way that is probably not how the library is meant to be used.
+
+However, after searching for an hour I still think the Django admin interface is the most tightly integrated system for making a simple CRUD application. For example, if I were to use Django and an external frontend for the admin interface, I would need to add stuff like login which of course adds time, and to be honest I've had my fair share of CRUD apps this month. I also think most modern interfaces have way too much whitespace compared to the Django admin interface, which is nice and dense.
