-Fern supports self-hosting so that you can run your docs site on your own infrastructure.
+<Note>Self-hosted documentation is only available for the enterprise plan.</Note>
+
+Fern documentation websites are hosted on Fern's infrastructure by default. Self-hosting allows you to deploy your documentation site on your own infrastructure to meet specific security or compliance requirements.
+
+## When to Use Self-Hosting
+
+Self-hosting is typically required for organizations that operate without internet access, have strict compliance requirements, or need full control over their documentation servers.
+
+When you self-host, you're responsible for server setup, security, maintenance, and deciding how to make the documentation accessible to your users.
+
+<Warning>
+Unless you have specific requirements that prevent using Fern's default hosting, we recommend **using our managed hosting solution** for easier setup and maintenance.
+</Warning>
+
+### Feature Support
+
+Self-hosted deployments include core Fern documentation website features like auto-generated API references, interactive documentation, SDK code snippets, search, and customizable branding. 
+
+However, features requiring external connections aren't supported, including [Ask Fern](/ask-fern/getting-started/what-is-ask-fern) (AI chat), [analytics](/integrations/overview), [live API key population](/docs/authentication/api-key-injection), and [SSO integrations](/docs/authentication/sso).
+
+<Info title="Extended feature support">
+**PDF export** and **offline AI chat functionality** are in development for self-hosted deployments. [Email us](mailto:[email protected]) if you're interested in these features.
+</Info>
+
+## Setup Process
+
+Fern provides your documentation site as a ready-to-run Docker container that you can deploy on your own infrastructure.
+
+1. **Download the Docker image** - Fern provides the location of the most up-to-date Docker image containing the documentation frontend
+1. **Upload your fern folder** - Add your documentation source files to the container
+1. **Run the container** - Spin up your local server using standard Docker commands
+1. **Configure hosting** - Set up your server environment and decide how to publish/share the documentation
+1. **Receive updated Docker images** - Fern releases new versions of the Docker image that your team can evaluate and deploy when ready.
