+# coleam00/Archon
+
+## Project
+
+- [Archon](https://github.com/coleam00/Archon)
+
+## Description
+
+Archon is a workflow engine for AI coding agents. The `archon` CLI runs deterministic development workflows for planning, implementation, validation, review, and PR creation across your projects.
+
+## Installation Method
+
+Downloaded as a pre-compiled binary from the [GitHub releases page](https://github.com/coleam00/Archon/releases) and placed in `/usr/local/bin`.
+
+## Other Notes
+
+The compiled Archon binary expects Claude Code to be installed separately. Set `CLAUDE_BIN_PATH` (or the corresponding Archon config option) if the `claude` binary is not on the default path.
