 # HollowPS
 
-Zenless Zone Zero server emulator
+A Server emulator for the game [`Zenless Zone Zero`](https://zenless.hoyoverse.com/en-us/)
+
+## Installation
+
+### From Source
+
+#### Requirements
+
+- [Rust](https://www.rust-lang.org/tools/install)
+
+**NOTE**: Nightly Rust is required to build the project. To install it, first install Rust itself, then run the following command:
+
+```sh
+rustup toolchain install nightly
+rustup default nightly
+```
+
+#### Building
+
+```sh
+git clone https://git.xeondev.com/reversedrooms/HollowPS.git
+cd HollowPS
+cargo install --path gameserver
+cargo install --path sdkserver
+```
+
+### From Prebuilt Binaries
+
+Navigate to the [Releases](https://git.xeondev.com/reversedrooms/HollowPS/releases)
+page and download the latest release for your platform.
+
+## Usage
+
+To begin using the server, you need to run both the SDK server and the game server.
+
+If you installed from source, Rust's installer should have added .cargo/bin to your
+path, so simply run the following:
+
+```sh
+nap-gameserver
+nap-sdkserver
+```
+
+If you installed from prebuilt binaries, navigate to the directory where you downloaded
+the binaries and run the following:
+
+```sh
+./nap-gameserver
+./nap-sdkserver
+```
+
+## Configuration
+
+The game server can be configured using a `.env` file. The file contains one configurable
+option, `SKIP_TUTORIAL`, which is set to 0 by default.
+
+If you have a `.env` file in the **same** directory as your executable, then this
+is the file that will be loaded. Otherwise, upon _first_ running the `gameserver`
+executable, it will create `{FOLDERID_RoamingAppData}\nap-gameserver\.env`
+(`C:\Users\{user}\AppData\Roaming\nap-gameserver\.env`) for you, and will source
+from this config instead.
