+**Note on Matching:**
+
+- When using a `String` as the matching type, the values in `triggers.include.*` and `triggers.exclude.*` require exact matches. This means that the names of branches or repositories must exactly match the specified string to either trigger or prevent triggering the automation.
+- For more precise control, use a regular expression (regex) format: `r/REGEX_PATTERN/`.

+- Implicit triggers are the default behavior if the automation doesn't have explicit triggers configured.
+- The automation runs for all branches and repositories if neither include nor exclude is specified.
+
+**Exclude/Include prioritization**
+
+- Exclude overrides the include option. Thus, a repo will be excluded when it matches the include and exclude lists.

+    In the following example, the automations in the file will be triggered for all repositories that contain the string `feature`, except for the repository `my_feature`

 ## Action-Level Execution Control
 
 gitStream provides intelligent action-level execution control that automatically skips certain actions based on the original triggering event. This feature helps reduce noise and ensures that AI-powered and code-related actions only execute when there are actual code changes, improving efficiency across all supported providers (GitLab, Bitbucket, and GitHub).

 With implicit triggers (no explicit triggers configured), `describe-changes` will only execute when the automation is triggered by code changes, while `add-reviewers` follows the current default behavior.
