# Extensions Use subfolders under the `extensions` folder to house extensions to the final unified hosts file. Currently this repo includes two extensions: `social` for common social media sites, and `porn` for porn sites. You can optionally add either or both to your final unified file. Here's a sample call to include the `porn` extension. **Using Python 3**: python3 updateHostsFile.py --extensions porn social or, in short form: python3 updateHostsFile.py -e porn social **Using Python 2.7**: python updateHostsFile.py --extensions porn social or, in short form: python updateHostsFile.py -e porn social More built-in extensions are coming soon.
