+

+
+## Where to Find Nightly Releases
+
+- **Jan's GitHub Repository**: Visit the [Download section](https://github.com/janhq/jan?tab=readme-ov-file#download) of Jan's GitHub repository for the latest nightly release.
+
+- **Discord Channel**: Nightly releases are also announced in our [Discord channel](https://discord.com/channels/1107178041848909847/1191638499355537418).
+
+## Automatic Updates
+
+Once you install a nightly build, the application will automatically prompt you to update each time it is restarted, ensuring you always have the latest version.
+
+## Running Stable and Nightly Versions Simultaneously
+
+If you wish to use both the stable and nightly versions of Jan, follow these steps:
+
+1. Install the stable version as usual.
+2. For the nightly build, choose a different installation directory to avoid conflicts.
+3. Ensure that you clearly label or create shortcuts for each version to avoid confusion.
