-# Fediversity Panel
-
-The Fediversity Panel is a web service for managing Fediversity deployments with a graphical user interface, written in Django.
-
-## Development
-
-- To obtain all tools related to this project, enter the development environment with `nix-shell`.
-
-  If you want to do that automatically on entering this directory:
-
-  - [Set up `direnv`](https://github.com/nix-community/nix-direnv#installation)
-  - Run `direnv allow` in the directory where repository is stored on your machine
-
-    > **Note**
-    >
-    > This is a security boundary, and allows automatically running code from this repository on your machine.
-
-- Run NixOS integration tests and Django unit tests:
-
-  ```bash
-  nix-build -A tests
-  ```
-
-- List all available Django management commands with:
-
-  ```shell-session
-  manage
-  ```
-
-- Run the server locally
-
-  ```shell-session
-  manage runserver
-  ```
-
-- Whenever you add a field in the database schema, run:
-
-  ```console
-  manage makemigrations
-  ```
-
-  Then before starting the server again, run:
-
-  ```
-  manage migrate
-  ```
