+### Using a Custom Base Branch
+By default, malas pr compares your current branch against the detected base branch (typically main). You can override this by specifying a different base branch using the --base option:
+```bash
+# Compare 'development' branch against 'staging' instead of 'main'
+malas pr --base staging
+
+# Compare 'feature-branch' against 'develop'
+malas pr --base develop
+```
 This mode will:
 - Automatically detect your current branch
 - Find all commits since the base branch (main/master)
