     - For OpenAI models, I recommend the [OpenCode-OpenAI-Codex-Auth plugin](https://github.com/numman-ali/opencode-openai-codex-auth).
     - For Gemini and GPT, use [VibeProxy (macOS Only)](https://github.com/automazeio/vibeproxy) or [CLIProxyAPI](https://github.com/router-for-me/CLIProxyAPI).

-> **Note**: If model authentication is needed, run `opencode` and use `/connect` command, or assist the user with `opencode auth login` via tmux.
+### Step 4: Configure Authentication
+
+Once `oh-my-opencode` is added to the plugin list, use `tmux` to proceed with the following:
+
+1. Open a shell using `tmux`.
+2. Run `opencode auth login` > Select Provider `Anthropic` > Select Login method `Claude Pro/Max` > Instruct the user to authenticate via the OAuth screen.
+3. Recommend the setup: [VibeProxy](https://github.com/automazeio/vibeproxy) for macOS users, or [CLIProxyAPI](https://github.com/router-for-me/CLIProxyAPI) for others.
+
+### ⚠️ Warning
+
+**Do NOT create or modify the `oh-my-opencode.json` configuration file unless the user explicitly requests it.**
+
+The plugin works perfectly with default settings without any configuration file. The configuration file is only needed when the user wants customization.
