 ## Installation
 
+### Build and run from Gitea
+
+You need access to this private Gitea repository and an internet connection to
+download the build dependencies.
+
+**Requirements**
+
+- **Linux:** Install Git and a C compiler/linker (`build-essential` on
+  Ubuntu/Debian), then install **Rust 1.91 or newer** using
+  [rustup](https://rust-lang.org/tools/install/).
+- **Windows:** Install [Git for Windows](https://git-scm.com/download/win)
+  and [Rust](https://rust-lang.org/tools/install/). Accept the prompt to
+  install Visual Studio C++ Build Tools, using the **Desktop development
+  with C++** workload. Reopen PowerShell after installation.
+
+**Download and build**
+
+Run these commands in a Linux terminal or Windows PowerShell. Authenticate
+with Gitea when prompted. The first build may take several minutes.
+
+```sh
+git clone --branch develop https://git.bloggin.space/dumbgoy/soulseek-rs-modded.git
+cd soulseek-rs-modded
+cargo build --release -p soulseek-rs
+```
+
+**Run on Linux**
+
+```sh
+./target/release/soulseek-rs
+```
+
+**Run on Windows (PowerShell)**
+
+```powershell
+.\target\release\soulseek-rs.exe
+```
+
+Log in with your Soulseek account. Press **s** to search, enter your query,
+and press **Enter**. Focus the results pane with **2**, highlight a track,
+then press **Shift+D** to download all files directly in its remote folder,
+including files absent from the search results. **Space** selects individual
+files and **Enter** downloads that selection. Press **?** for shortcuts or
+**q** to quit.
+
+**Update later**
+
+Close the application, run these commands inside `soulseek-rs-modded`, then
+launch it again with the command for your operating system:
+
+```sh
+git pull --ff-only
+cargo build --release -p soulseek-rs
+```
