 There is a builtin proxy, but you can also host your one! Just clone the repo, run `pnpm i` (following CONTRIBUTING.MD) and run `pnpm prod-start`, then you can specify `http://localhost:8080` in the proxy field.
 MS account authentication will be supported soon.
 
+### Docker Files
+
+- [Main Dockerfile](./Dockerfile) - for production build & offline/private usage. Includes full web-app + proxy server for connecting to Minecraft servers.
+- [Proxy Dockerfile](./Dockerfile.proxy) - for proxy server only - that one you would be able to specify in the proxy field on the client (`docker build . -f Dockerfile.proxy -t minecraft-web-proxy`)
+
+In case of using docker, you don't have to follow preparation steps from CONTRIBUTING.MD, like installing Node.js, pnpm, etc.
