+
+Interactive wizard — guided setup for a new repo:
+
+```bash
+gitkit init
+```
+
+Or use commands directly:
 
 ```bash
-# Install a built-in hook
-gitkit hooks init commit-msg conventional-commits
+gitkit hooks add conventional-commits
+gitkit ignore add rust,vscode,agentic
+gitkit attributes init
+gitkit config apply defaults
+```
 
-# Install a custom hook command
-gitkit hooks init pre-push "cargo test"
+---
 
-# List installed hooks
-gitkit hooks list
+## `gitkit init`
 
-# Generate a .gitignore
-gitkit ignore add rust,vscode
+Interactive wizard that guides you through configuring a repo step by step.
+
+- Hooks — built-ins pre-selected, or add a custom command
+- `.gitignore` — filterable search across all gitignore.io templates + built-ins
+- `.gitattributes` — line endings and binary file presets
+- Git config — 6 individual options, recommended ones pre-selected
 
-# Apply line endings preset
-gitkit attributes init
+```
+gitkit init
 ```
