## What it is
A read-only Git mirror of OpenBSD's official CVS source repository containing the complete operating system source tree, including the kernel, userland tools, OpenSSH, and PF firewall. Contributions are not accepted via pull requests; diffs must be sent to the tech@ mailing list.

## Use cases
- browse OpenBSD kernel source code online
- track changes to the OpenBSD source tree via git
- study OpenSSH and PF firewall implementations
- build OpenBSD from source
- search OpenBSD userland code for porting
- follow -current development changes

## When to choose
- you need Git-based access to OpenBSD's full source tree
- you want to study or port OpenBSD code such as OpenSSH or pf
- you track OpenBSD -current development history

## When to avoid
- you want to contribute code - use the tech@ mailing list with diffs instead
- you just want to install or run OpenBSD - download official release media instead
- you need a general-purpose Git hosting workflow with pull requests
