## Scan Options

You can run the scan in one of three modes:

    Organization Scan: Use the --org flag to scan all repositories within an organization.
    Repository Scan: Use the --repo flag to scan a specific repository (format: owner/repo or a full GitHub URL).
    User Scan: Use the --user flag to scan all repositories for a specific user.

## GitHub Personal Access Token (PAT)

To access repository content, you'll need a GitHub Personal Access Token (PAT) provided via the --token flag:

    Organization Scans: The PAT must include the repo and read:org scopes.
    User/Repository Scans: The PAT should have repo (for private repos) or public_repo (for public repos).

### How to Get Your GitHub PAT

1. Sign in to GitHub and click on your profile picture.
2. Navigate to Settings → Developer settings → Personal access tokens.
3. Click Generate new token, provide a descriptive name, and select the required scopes.
4. Generate and copy the token.

## Sample Command

To scan all repositories in an organization called myorg with the default keywords, run:

```python
python CxGithubActionsScan.py --org myorg --token YOUR_GITHUB_PAT
```
