+### Using Ollama
+
+openwork can use local Ollama models without an API key.
+
+```bash
+# Install and start Ollama
+ollama serve
+
+# Pull at least one local model
+ollama pull llama3.1:8b
+
+# Optional: point openwork at a non-default Ollama server
+export OLLAMA_BASE_URL=http://127.0.0.1:11434
+
+# OLLAMA_HOST also works, including host:port values like 127.0.0.1:11434
+export OLLAMA_HOST=127.0.0.1:11434
+```
+
+If you need the setting to persist for the app, add `OLLAMA_BASE_URL=...` or `OLLAMA_HOST=...` to `~/.openwork/.env`.
