Burrow is an open source tool for burrowing through firewalls, built by teenagers at [Hack Club](https://hackclub.com/).

`burrow` provides a simple command-line tool to open virtual interfaces and direct traffic through them.
Routine verification now runs unprivileged with `cargo test --workspace --all-features`; only tunnel startup needs elevation.

The repository now carries its own design and deployment record:

- [Constitution](./CONSTITUTION.md)
- [Agent Instructions](./AGENTS.md)
- [Burrow Evolution](./evolution/README.md)
- [WireGuard Rust Lineage](./docs/WIREGUARD_LINEAGE.md)
- [Protocol Roadmap](./docs/PROTOCOL_ROADMAP.md)
- [Forward Email Runbook](./docs/FORWARDEMAIL.md)

Checkout [GETTING_STARTED.md](./docs/GETTING_STARTED.md) for build instructions and [GTK_APP.md](./docs/GTK_APP.md) for the Linux app. Forge and deployment scaffolding live in [`flake.nix`](./flake.nix), [`nixos/`](./nixos), and [`.forgejo/workflows/`](./.forgejo/workflows/). Hosted mail backup operations live in [`docs/FORWARDEMAIL.md`](./docs/FORWARDEMAIL.md) and [`Tools/forwardemail-custom-s3.sh`](./Tools/forwardemail-custom-s3.sh).

Agent and governance-sensitive work should start with [AGENTS.md](./AGENTS.md), [CONSTITUTION.md](./CONSTITUTION.md), and the relevant BEPs under [`evolution/proposals/`](./evolution/proposals/). Identity and bootstrap metadata now live in [`contributors.nix`](./contributors.nix).
