| # Configuration Overview | |
| Chat UI handles configuration with environment variables. The default config for Chat UI is stored in the `.env` file, which you may use as a reference. You will need to override some values to get Chat UI to run locally. This can be done in `.env.local` or via your environment. The bare minimum configuration to get Chat UI running is: | |
| ```ini | |
| MONGODB_URL=mongodb://localhost:27017 | |
| HF_TOKEN=your_token | |
| ``` | |
| The following sections detail various sections of the app you may want to configure. | |
