+### Uninstall
+
+To uninstall OpenCode and clean up all related files:
+
+```bash
+opencode uninstall
+```
+
+This will:
+
+- Automatically detect your installation method (curl, npm, pnpm, bun, brew)
+- Remove the OpenCode binary
+- Delete all data directories (sessions, cache, config, state)
+
+To keep your user data (sessions, config) while removing the binary:
+
+```bash
+opencode uninstall --keep-data
+```
+
