+OpenCode is an agentic coding tool for the terminal.
+
+## Install
+
+Install [OpenCode](https://opencode.ai):
+
+```shell
+curl -fsSL https://opencode.ai/install | bash
+```
+
+## Usage with Ollama
+
+Configure OpenCode to use Ollama:
+
+```shell
+ollama config opencode
+```
+
+This will prompt you to select models and automatically configure OpenCode to use Ollama.
+
+<Accordion title="Manual Configuration">
+
+Add the Ollama provider to `~/.config/opencode/opencode.json`:
+
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "provider": {
+    "ollama": {
+      "npm": "@ai-sdk/openai-compatible",
+      "name": "Ollama (local)",
+      "options": {
+        "baseURL": "http://localhost:11434/v1"
+      },
