+# Building Zed for Windows
+
+> [!NOTE]
+> The following commands may be executed in any shell.
+
+## 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 Rust wasm toolchain:
+
+  ```bash
+  rustup target add wasm32-wasi
+  ```
+
+- Install [Visual Studio](https://visualstudio.microsoft.com/downloads/) with optional component `MSVC v*** - VS YYYY C++ x64/x86 build tools`. 
+
+> [!NOTE]
+> `v***` is your VS version and `YYYY` is year when your VS was released.
+
+## 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
+```
+
+## 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`.
