Check if `docker` & `docker compose` are installed correctly 2. Open 3 Terminal Windows (Or 2 depends on) 3. Change the ip in `velocity.toml` (Line 75 & 76) to your local ip (This gets reworked in the Future) ## To Do - [ ] Build system for the whole dev stack - [ ] Networking between Containers ## Handling the stack 1. Start Dev Proxy ```bash docker compose -f dev-proxy/proxy-compose.yml up ``` 2. Start Dev Fallback ```bash docker compose -f fallback-compose.yml up ``` 3. Start Dev Main ```bash docker compose -f main-compose.yml up ``` 4. Start Minecraft with Version 1.21.1 (Fabric highly preferred) 5. Add Server -> Server Address -> `localhost` 6. Connect
