 # Gymboard
 Leaderboards for your local community gym.
+
+## Development
+Gymboard is comprised of a variety of components, each in its own directory, and with its own project format. Follow the instructions in the README of the respective project to set that one up.
+
+A `docker-compose.yml` file is defined in this directory, and it defines a set of services that may be used by one or more services. Install docker on your system if you haven't already, and run `docker-compose up -d` to start the services.

+# Gymboard-CDN
+
+To avoid having to do expensive and complex computations in the main Gymboard API to handle user video uploads, that functionality is provided by this _Gymboard-CDN_ project.
+
+This CDN offers basic, unauthenticated upload and download capabilities, as well as asynchronous processing of video files to reduce disk usage.
+
+It offers the following endpoints:
+- `POST /uploads` - Upload files here.
+- `GET /uploads/{id}` - Fetch uploaded files.
