 ## Ignoring automatic commands in PRs
 
-In some cases, you may want to automatically ignore specific PRs . Qodo Merge enables you to ignore PR with a specific title, or from/to specific branches (regex matching).
+Qodo Merge allows you to automatically ignore certain PRs based on various criteria:
+
+- PRs with specific titles (using regex matching)
+- PRs between specific branches (using regex matching)
+- PRs that don't include changes from specific folders (using regex matching)
+- PRs containing specific labels
+- PRs opened by specific users
+
+### Example usage

 To ignore PRs with a specific title such as "[Bump]: ...", you can add the following to your `configuration.toml` file:

+#### Ignoring PRs containg specific labels
+
+To ignore PRs containg specific labels, you can add the following to your `configuration.toml` file:
+
+``` 
+[config]
+ignore_pr_labels = ["do-not-merge"]
+```
+
+Where the `ignore_pr_labels` is a list of labels that when present in the PR, the PR will be ignored.
+
+#### Ignoring PRs from specific users
+
+Qodo Merge automatically identifies and ignores pull requests created by bots using:
+
+- GitHub's native bot detection system
+- Name-based pattern matching
+
+While this detection is robust, it may not catch all cases, particularly when:
+
+- Bots are registered as regular user accounts
+- Bot names don't match common patterns
+
+To supplement the automatic bot detection, you can manually specify users to ignore. Add the following to your `configuration.toml` file to ignore PRs from specific users:
+```
+[config]
+ignore_pr_authors = ["my-special-bot-user", ...]
+```
+
+Where the `ignore_pr_authors` is a list of usernames that you want to ignore.
