+## Source Code Reference
+
+Source code for dependencies is available in `opensrc/` for deeper understanding of implementation details.
+
+See `opensrc/sources.json` for the list of available packages and their versions.
+
+Use this source code when you need to understand how a package works internally, not just its types/interface.
+
+### Fetching Additional Source Code
+
+To fetch source code for a package or repository you need to understand, run:
+
+```bash
+npx opensrc <package>           # npm package (e.g., npx opensrc zod)
+npx opensrc pypi:<package>      # Python package (e.g., npx opensrc pypi:requests)
+npx opensrc crates:<package>    # Rust crate (e.g., npx opensrc crates:serde)
+npx opensrc <owner>/<repo>      # GitHub repo (e.g., npx opensrc vercel/ai)

+- **Multi-account support** with automatic rate limit rotation

+## 👥 Multi-Account Support
+
+Heavy users can configure up to 10 ChatGPT accounts. When one account hits rate limits, the plugin automatically switches to the next available account.
+
+### Adding Accounts
+
+**During initial login:**
+```bash
+opencode auth login
+# After first account: "You have 1 account(s). Add another? [y/N]: y"
+```
+
+**Add accounts later:**
+```bash
+codex-accounts add      # Opens browser OAuth
+codex-accounts list     # Show all accounts
+codex-accounts remove 1 # Remove account at index 1
+```
+
+### How It Works
+
+1. Request sent using current account
+2. If 429 (rate limit) received, marks account as rate-limited
+3. Automatically retries with next available account (up to 3 retries)
+4. Rate limit state persists across sessions
+
+### Storage
+
+Account metadata stored at:
+- **Linux/macOS:** `~/.local/share/opencode/openai-codex-accounts.json`
+- **Windows:** `%APPDATA%/opencode/openai-codex-accounts.json`
