+# System requirements
+
+There aren't any "minimum" system requirements as such, the server process is
+very light weight - it's just a single go binary, and it doesn't do any server
+side ML, so I feel it should be able to run on anything reasonable.
+
+We've used the server quite easily on small cloud instances, old laptops etc. A
+community member also reported being able to run the server on [very low-end
+embedded devices](https://github.com/ente-io/ente/discussions/594).

+# Self Hosting
+
+The entire source code for Ente is open source, including the servers. This is
+the same code we use for our own cloud service.
+
+> [!TIP]
+>
+> To get some context, you might find our [blog
+> post](https://ente.io/blog/open-sourcing-our-server/) announcing the open
+> sourcing of our server useful.
+
+## Getting started
+
+Start the server
+
+```sh
+git clone https://github.com/ente-io/ente
+cd ente/server
+docker compose up --build
+```
+
+Then in a separate terminal, you can run (e.g) the web client
+
+```sh
+cd ente/web
+git submodule update --init --recursive
+yarn install
+NEXT_PUBLIC_ENTE_ENDPOINT=http://localhost:8080 yarn dev
+```
+
+That's about it. If you open http://localhost:3000, you will be able to create
+an account on a Ente Photos web app running on your machine, and this web app
+will be connecting to the server running on your local machine at
+localhost:8080.
+
+## Next steps
+
+* More details about the server are in its
+  [README](https://github.com/ente-io/ente/tree/main/server#readme)
+
+* More details about running the server (with or without Docker) are in
+  [RUNNING](https://github.com/ente-io/ente/blob/main/server/RUNNING.md)
+
+* If you have questions around self-hosting that are not answered in any of the
+  existing documentation, you can ask in our [GitHub
+  Discussions](https://github.com/ente-io/ente/discussions). **Please remember
+  to search first if the query has been already asked and answered.**
+
+## Contributing!
+
+While we would love to provide a completely seamless self-hosting experience,
+right now we do not have the engineering bandwidth to answer all queries,
+document everything exactly etc. We will try (that's why we're writing this!),
+but we also hope that community members will step up to fill any gaps.
+
+One particular way in which you can help is by adding new [guides](guides/) on
+this help site. The documentation is written in Markdown and adding new pages is
+[easy](https://github.com/ente-io/ente/tree/main/docs#readme). Editing existing
+pages is even easier: at the bottom of each page is an _Edit this page_ link.
