 Everything else will happen automagically.
 
-## Setup
+## Customize
 
-The plugin will install CaptainHook and make sure the git-hooks are installed. The configuration though is still 
-done using CaptainHook.
+You can set a custom name for your hook configuration and a custom path to your .git directory
+if it is not located in the same directory as your *composer.json* file.
+Just add these values to your *composer.json* in the *extra* section first.
+```json
+{
+  "extra": {
+    "captainhook-config": "hooks.json",
+    "captainhook-git-dir": "../.git"
+  }
+  
+}
 
-So after first installation you should run `vendor/bin/captainhook  configure -e` and then commit the file 
-`captainhook.json` to version control. Then everyone using your project will also have the configured hooks installed.
+```
+
+If you want to see the installation in action have a look at this short installation video.

 ## A word of warning
 
 It is still possible to commit without invoking the hooks. 
-So make sure you run appropriate backend-sanity checks on 
-your code!
