+## Installing a model that runs on your own machine
+
+[LLM plugins](https://llm.datasette.io/en/stable/plugins/index.html) can add support for alternative models, including models that run on your own machine.
+
+To download and run Llama 2 13B locally, you can install the [llm-mlc](https://github.com/simonw/llm-mlc) plugin:
+```bash
+llm install llm-mlc
+llm mlc pip install --pre --force-reinstall \
+  mlc-ai-nightly \
+  mlc-chat-nightly \
+  -f https://mlc.ai/wheels
+llm mlc setup
+```
+Then download the 15GB Llama 2 13B model like this:
+```bash
+llm mlc download-model Llama-2-7b-chat --alias llama2
+```
+And run a prompt through it:
+```bash
+llm -m llama2 'difference between a llama and an alpaca'
+```
+You can also start a chat session with the model using the `llm chat` command:
+```bash
+llm chat -m llama2
+```
