 **helpr** supports 3 labels :
-* `pr-available`
-* `pr-merged`
-* `pr-rejected`
+* `pr-available` when  a new PR referencing an issue is opened.
+* `pr-merged` when a PR referencing an issue is merged.
+* `pr-rejected` when a PR referencing an issue is rejected.
 
 When a PR for an issue is merged or rejected **helpr** will remove the `pr-available` label and add the respective merged or rejected label.
 
+## Configuring
+
+You can choose label names as per your liking :smile:
+
+Add a `helpr` object in your `.github/config.yml` file (and make the file if you don't already have it) like this:
+
+```yaml
+helpr:
+  opened: 'insert-label-for-pr-opened-here'
+  merged: 'insert-label-for-pr-merged-here'
+  rejected: 'insert-label-for-pr-rejected-here'
+```  
+
+Only override the ones that you want to change!
+
+The defaults are:
+```yaml
+opened: 'pr-available'
+merged: 'pr-merged'
+rejected: 'pr-rejected'
+```
