# Zed Zed is managed through Home Manager and installed from `nixpkgs-unstable` so the editor can move faster than the system channel. ## Extensions Extensions are declared in `programs.zed-editor.extensions`. Keep that list in source rather than duplicating it here; it changes more often than the operating model. The important rule is that registry themes must have both pieces: | Need | Example | | ------------------- | -------------------- | | Extension installed | `carbonfox` | | Theme selected | `Carbonfox - opaque` |
