 You describe what you want in plain English, an agent helps you write a spec in \*\*\*plain language, and \*codeplain renders the actual code. This is what [plain-forge](https://github.com/Codeplain-ai/plain-forge) sets up: a toolkit of skills, rules, and docs that plugs into your AI coding agent of choice — Claude Code, Codex, ForgeCode, OpenCode, or any other agent that reads from a standard skills directory — and turns a conversation into a complete `.plain` spec, then keeps maintaining it across the lifetime of the project.

+If you didn't install it during step 1, run it any time using your favorite Node package runner:
 
 ```bash
 npx plain-forge install
 ```
 
+The same command works with any other runner — pick whichever matches your toolchain:
+
+```bash
+# npm (bundled with Node.js)
+npx plain-forge install
+
+# pnpm
+pnpm dlx plain-forge install
+
+# Bun
+bunx plain-forge install
+
+# Yarn (Berry, v2+)
+yarn dlx plain-forge install
+
+# Deno (npm: specifier, needs permissions to write the skills directory)
+deno run -A npm:plain-forge install
+```
+
+Every runner downloads `plain-forge` on demand and runs it without adding it to your project's dependencies. The package exposes a `plain-forge` binary, so no runner needs an extra `--package` flag.
+
+`install` fails if plain-forge is already installed at the target — to refresh an existing installation to the latest skills, rules, and docs, use `update` instead (swap in your runner of choice):
+
+```bash
+npx plain-forge update
+```
