+# Environment Variables and Ports
+
+The self hosted instance relies on few endpoints in Museum as well as on the Web
+App. Additionally, this document also covers information about what ports are mapped
+to which Web app and etc. 
+
+Here's the list of important variables that the self hoster should know about:
+
+## Museum
+
+1. `NEXT_PUBLIC_ENTE_ENDPOINT`
+
+The above endpoint is used to configure Museums endpoint. Where Museum is running
+and which port it is listening on. This endpoint should be configured for all the
+apps to connect to your self hosted endpoint. 
+
+All the apps (regardless of platform) by default connect to api.ente.io - which is 
+our production instance of Museum.
+
+## Web Apps
+
+> [!IMPORTANT]
+> Web apps don't need to be configured with the below endpoints. Web App Environment
+> variables are being documented here just so that the users know everything in detail.
+> Checkout [Configuring your Server](/self-hosting/museum) to configure endpoints for
+> particular app.
+
+In Ente, all the web apps are separated into different NextJS Apps. Hence, all of them
+are configured via Environment Variables. The photos app is the Ente Photos which has
+the information and knowledge of all the other needful web apps like albums, cast and etc.
+
+1. `NEXT_PUBLIC_ENTE_ALBUMS_ENDPOINT`
+
+This environment variable is used to configure and declare the endpoint for the Albums
+Web App.
+
+# Ports
+
+The below format is according to how ports are mapped in Docker. 
+Typically,`<host>:<container-port>`
+
+1. `8080:8080`: Museum (Ente's Server)
+2. `3000:3000`: Ente Photos Web App
+3. `3001:3001`: Ente Accounts Web App
+4. `3003:3003`: [Ente Auth](https://ente.io/auth/)
+5. `3004:3004`: [Ente Cast Web App](http://ente.io/cast)
