## Documentation
Check out the full documentation here [laminar.sh/docs](https://laminar.sh/docs).
## Getting started
The fastest and easiest way to get started is with our managed platform -> [laminar.sh](https://laminar.sh)
### Self-hosting with Docker compose
Laminar is very easy to self-host locally. For a quick start, clone the repo and start the services with docker compose:
```sh
git clone https://github.com/lmnr-ai/lmnr
cd lmnr
docker compose up -d
```
This will spin up a lightweight but full-featured version of the stack. This is good for a quickstart
or for lightweight usage. You can access the UI at http://localhost:5667 in your browser.
You will also need to properly configure the SDK, with `baseUrl` and correct ports. See [guide on self-hosting](https://laminar.sh/docs/hosting-options#self-hosted-docker-compose).
For production environment, we recommend using our [managed platform](https://laminar.sh) or `docker compose -f docker-compose-full.yml up -d`.
### Configuring LLM provider (optional)
Frontend AI features (chat-with-trace, SQL-with-AI) and server-side AI workers require an LLM provider. Configure one in your `.env` file at the repo root.
Pick one of the following provider setups. `LLM_MODEL_SMALL|MEDIUM|LARGE` are optional — per-provider defaults apply when unset. `LLM_DEFAULT_HEADERS_JSON` is optional for any provider or gateway that requires static headers.
```sh
# Optional for any prExcerpt of 8,213 characters
