 # Mercury
+
+ActivityPub server implementation (hopefully, eventually),
+currently mostly a way for me to play around with writing an API server in TypeScript.
+
+## Configuration
+
+For now, check out `src/config.ts`, the names should be mostly self explanatory.
+Consider all environment variables required.
+
+## Development commands
+
+- Building the server: `pnpm build`
+- Migrating the database: `pnpm migrate`
+- Watching for changes and reloading the server automatically: `pnpm dev`
+- Formatting: `pnpm format`
+- Linting (if you don't have an ESLint plugin): `pnpm format`
+
+## License
+
+Mercury is licensed under the GNU Affero General Public License, version 3 **only**.
