+# Setup
+
+## Proven Setup Signals
+
+| Signal | Detail |
+|---|---|
+| requirements.txt | aiohttp, aiohttp-socks, paramiko |
+| README files | README.md |
+
+## Setup Path
+
+- Create a Python virtual environment and install packages from the requirements file before running project commands.
+
+## Environment Rules
+
+- Keep local secrets out of Git.
+- Put generated build output outside source control.
+- Prefer a clean checkout when validating setup instructions.
+- Record the exact command that works in the readiness issue before closing it.
+
+## Current Gaps
+
+- Repository description still needs a project-specific maintainer rewrite.
