Forge aims for guided, low-configuration onboarding — a new repo is usually productive in about five minutes. Install once, configure a repo once, do a task, and the ledger starts paying off on day two. (It is low-configuration, not zero-configuration: you still install the CLI, run forge init in each repo, and some paths assume Bash, Git, and jq.)

1. Install (once)

The recommended paths need no token and no clone:

2. Configure a repo (once per repo)

Now Claude Code, Codex, Cursor, Gemini, Aider, Copilot, Windsurf, Zed, and Continue all read the same rules — each from its own native file. Change a rule later by editing source/rules.json (or dropping a per-repo .forge/rules.json), then run forge sync.

3. Use the cognitive substrate

If forge substrate says ASK FIRST, ask the returned questions before editing.

4. Use the extras

5. Day two: the ledger is learning

Everything the substrate learned on day one — cortex lessons, remembered facts, verified code — landed as claims in .forge/ledger/.

Next: fold a teammate’s ledger in, conflict-free, over plain git.
