+## Contributing
+
+1. Install go (on arch: `pacman -S go`)
+2. In the root directory of the repo, run `podman compose up -d`
+3. Obtain [golang migrate](https://github.com/golang-migrate/migrate). You may need to download the CLI directly from a release
+4. In `backend`, run `migrate -source file://$(pwd)/migrations -database postgres://postgres:test@localhost:5432/postgres?sslmode=disable up`
+5. In `backend`, run `go run .`
+
+### Adding new dependencies
+`go mod tidy`
+
+### Formatting
+`gofmt -w -s .`
+
+### Creating new DB migrations
+Create a new file with an incremented prefix number, a human readable string, and ending with `.up.sql`, with a corresponding `.down.sql` that has the same number prefix to revert your change. Apply these with golang-migrate
