 # Devcontainer Features
 
-Custom devcontainer features for Antigravity IDE development environments.
+A collection of reusable [Dev Container Features](https://containers.dev/implementors/features/) for development environments.
 
 ## Features
 
-### `antigravity-nix`
+| Feature | Description |
+|---------|-------------|
+| [antigravity-nix](src/features/antigravity-nix) | Creates vscode user, installs Nix with flakes, and essential tools |
+| [node](src/features/node) | Installs Node.js from NodeSource with version selection |
+| [gcloud-cli](src/features/gcloud-cli) | Installs Google Cloud CLI via official Debian packages |
+| [dataform-cli](src/features/dataform-cli) | Installs Dataform CLI via npm |
 
-A consolidated feature that provides:
-- **vscode user** (uid/gid 1000) with passwordless sudo
-- **Nix package manager** (single-user mode with flakes enabled)
-- **Essential tools**: wget, git, curl, sudo, ca-certificates
+## Usage
 
-#### Usage
+Add features to your `devcontainer.json`:
 
 ```json
 {
-  "features": {
-    "ghcr.io/duizendstra/devcontainer-features/antigravity-nix:1": {}
-  }
+    "features": {
+        "ghcr.io/duizendstra/devcontainer-features/antigravity-nix:1": {},
+        "ghcr.io/duizendstra/devcontainer-features/node:1": {
+            "version": "lts"
+        },
+        "ghcr.io/duizendstra/devcontainer-features/gcloud-cli:1": {},
+        "ghcr.io/duizendstra/devcontainer-features/dataform-cli:1": {}
+    }
 }
 ```
 
-## Publishing
+## Feature Dependencies
 
-Features are automatically published to `ghcr.io/duizendstra/devcontainer-features/` when pushed to main.
+```
+antigravity-nix → node → dataform-cli
+               → gcloud-cli
+```
+
+Features are automatically ordered based on their dependencies.
 
 ## Development
 
-To test features locally, use the dev container CLI:
+### Structure
+
+```
+src/features/
+├── antigravity-nix/
+│   ├── devcontainer-feature.json
+│   └── install.sh
+├── node/
+├── gcloud-cli/
+└── dataform-cli/
+
+test/features/
+└── (test scripts for each feature)
+```
+
+### Testing
 
 ```bash
 devcontainer features test -f antigravity-nix
 ```
