2. If you would rather provide your own ports, run the following command and replace `XXX` with your OR port, `YYY` with your obfs4 port, and `address@example.com` with your email address. Don't forget the semicolon after the environment variables.

   ```

   OR_PORT=XXX PT_PORT=YYY EMAIL=address@example.com; \

   docker run -d \

     -e "OR_PORT=$OR_PORT" -e "PT_PORT=$PT_PORT" -e "EMAIL=$EMAIL" \

     -p "$OR_PORT":"$OR_PORT" -p "$PT_PORT":"$PT_PORT" \

   OR_PORT=XXX PT_PORT=YYY EMAIL=address@example.com; \\

   docker run -d \\

     -e "OR_PORT=$OR_PORT" -e "PT_PORT=$PT_PORT" -e "EMAIL=$EMAIL" \\

     -p "$OR_PORT":"$OR_PORT" -p "$PT_PORT":"$PT_PORT" \\
