 ### Install with Your Coding CLI
 
-See the **[Helm chart docs](https://openabdev.github.io/openab)** for per-agent install commands (Kiro CLI, Claude Code, Codex, Gemini) and values reference.
+Use one of these prompts with any coding CLI (Kiro CLI, Claude Code, Codex, Gemini, OpenCode, etc.) on the host that has `helm` and `kubectl` access to your cluster:
+
+**Kiro CLI (default):**
+> Install openab on my local k8s cluster using the Helm chart from https://openabdev.github.io/openab. Set `agents.kiro.discord.botToken` from the `DISCORD_BOT_TOKEN` environment variable and `agents.kiro.discord.allowedChannels[0]` to <REPLACE_WITH_YOUR_CHANNEL_ID>. After install, follow the NOTES output to authenticate, then restart the deployment.
+
+**OpenCode:**
+> Install openab on my local k8s cluster using the Helm chart from https://openabdev.github.io/openab. Disable the default `kiro` agent, create an `opencode` agent with `agents.opencode.preset=opencode`, set `agents.opencode.discord.botToken` from the `DISCORD_BOT_TOKEN` environment variable, and set `agents.opencode.discord.allowedChannels[0]` to <REPLACE_WITH_YOUR_CHANNEL_ID>. After install, run `kubectl exec -it deployment/openab-opencode -- opencode auth login`, then restart `deployment/openab-opencode`.
+
+For Codex, Claude Code, and Gemini, use the same `agents.<name>.preset=<preset>` pattern.
