 ### Optional
 - `GITHUB_TOKEN`: [GitHub personal access token](https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/creating-a-personal-access-token). **Attention: if this is set, the token will be transmitted to your specified Gitea instance!**
-- `MIRROR_PRIVATE_REPOSITORIES`: If set to `true`, your private GitHub repositories will also be mirrored to gitea. The `GITHUB_TOKEN` parameter must be set for this to work.
+- `MIRROR_PRIVATE_REPOSITORIES`: If set to `true` or `1`, your private GitHub repositories will also be mirrored to gitea. The `GITHUB_TOKEN` parameter must be set for this to work.
+- `SKIP_FORKS`: If set to `true` or `1`, forks will NOT be mirrored.
 - `DELAY`: How often to check for new repositories in seconds. Default is 3600 (1 hour).
 - `DRY_RUN`: If set to `true` or `1`, the script will only log what would be done, but not actually create any mirror.
