+# Building Zed for Linux
+
+## Repository
+
+After cloning the repository, ensure all git submodules are initialized:
+
+```shell
+git submodule update --init --recursive
+```
+
+## Dependencies
+
+- Install [Rust](https://www.rust-lang.org/tools/install). If it's already installed, make sure it's up-to-date:
+
+  ```bash
+  rustup update
+  ```
+
+- Install the necessary system libraries:
+
+  ```bash
+  script/linux
+  ```
+
+  If you prefer to install the system libraries manually, you can find the list of required packages in the `script/linux` file.
+
+## Backend dependencies
+
+> [!WARNING]
+> This section is still in development. The instructions are not yet complete.
+
+If you are developing collaborative features of Zed, you'll need to install the dependencies of zed's `collab` server:
+
+- Install [Postgres](https://www.postgresql.org/download/linux/)
+- Install [Livekit](https://github.com/livekit/livekit-cli) and [Foreman](https://theforeman.org/manuals/3.9/quickstart_guide.html)
+
+Alternatively, if you have [Docker](https://www.docker.com/) installed you can bring up all the `collab` dependencies using Docker Compose:
+
+```sh
+docker compose up -d
+```
+
+## Building from source
+
+Once you have the dependencies installed, you can build Zed using [Cargo](https://doc.rust-lang.org/cargo/).
+
+For a debug build:
+
+```
+cargo run
+```
+
+For a release build:
+
+```
+cargo run --release
+```
+
+And to run the tests:
+
+```
+cargo test --workspace
+```
+
+## Wayland & X11
+
+Zed has basic support for both modes. The mode is selected at runtime. If you're on wayland and want to run in X11 mode, you can set `WAYLAND_DISPLAY='' cargo run` to do so.
+
+## Troubleshooting
+
+### Can't compile zed
+
+Before reporting the issue, make sure that you have the latest rustc version with `rustup update`.
+
+### Cargo errors claiming that a dependency is using unstable features
+
+Try `cargo clean` and `cargo build`.
+
+### Vulkan/GPU issues
+
+If Zed crashes at runtime due to GPU or vulkan issues, you can try running [vkcube](https://github.com/krh/vkcube) (usually available as part of the `vulkaninfo` package on various distributions) to try to troubleshoot where the issue is coming from. Try running in both X11 and wayland modes by running `vkcube -m [x11|wayland]`. Some versions of `vkcube` use `vkcube` to run in X11 and `vkcube-wayland` to run in wayland.
+
+If you have multiple GPUs, you can also try running Zed on a different one (for example, with [vkdevicechooser](https://github.com/jiriks74/vkdevicechooser)) to figure out where the issue comes from.
