 ### Development with Containers
 
-If you don't have Go or Node installed locally, or prefer an isolated environment, you can use the provided Dockerfile. Note that the `.devcontainer` VS Code integration has encountered issues with some setups (e.g. Antigravity + Colima), so manual Docker commands are recommended as a fallback.
