 ## Prerequisites
 
 - Install and run either [Docker](https://docs.docker.com/get-started/get-docker/) or [OrbStack](https://docs.orbstack.dev/quick-start). OrbStack is a fast, Docker-compatible alternative for macOS (free for personal use).
-- - Ensure Docker has permission to bind to local ports (typically `80` or `8080`) and that no conflicting services are already using these ports. On macOS/Linux, you can check with `lsof -iTCP:80 -sTCP:LISTEN`. On Windows, you can check with `netstat -aon | findstr LISTENING | findstr :80` ([`netstat` docs](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/netstat), [`findstr` docs](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/findstr)). For background on identifying which process is listening on a TCP port, see Microsoft’s guide: [Determine which program uses or blocks specific TCP ports](https://learn.microsoft.com/en-us/troubleshoot/windows-server/performance/determine-which-program-use-block-tcp-ports).
