+A run-and-gun shooter inspired by Metal Slug and Counter-Strike.
 
 ## Setup
 
-> **Note:** CMake and OpenSSL are required. 
-
-### Windows
-
 The following tools are required:
 
 * CMake
 * Ninja
 * Clang
-  > Set your `CC` environment variable to the full path of `clang-cl.exe`
- 
-  > Set your `CMAKE_MT` environment variable to the full path of `mt.exe`, which can be found on your Windows SDK
-	> installation folder (usually `C:/Program Files (x86)/Windows Kits/10/bin/10.0.19041.0/x86/mt.exe`)
-
-1. Clone this repo.
-2. Clone the repositories under `dependencies.txt` except for SDL2.
-3. Unpack the **MSVC** archive under `dependencies` folder in this project's root. Rename the directory as `SDL2`.
-4. Build the following dependencies first:
-   - `portmidi`
-   - `libwebsockets` (follow the [instructions on building LWS](https://libwebsockets.org/lws-api-doc-master/html/md_README_8build.html))
-5. Build via CMake.
+* `autoconf` (macOS/*NIX)
+* `make` (macOS/*NIX)
+* `libtool` (*NIX)
+
+For Windows and macOS, it is recommended to use Chocolatey and Homebrew respectively, for retrieving the required tools.
+
+For *NIX, use whatever dependency manager you prefer to obtain the needed tools.
+
+### Windows
+
+1. Ensure your environment variables are set up.
+
+   > **Important:** Set your `CC` environment variable to the full path of `clang-cl.exe`
+
+   > **Important:** Set your `CMAKE_MT` environment variable to the full path of `mt.exe`, which can be found on your
+   > Windows SDK installation folder (usually `C:/Program Files (x86)/Windows Kits/10/bin/10.0.19041.0/x86/mt.exe`)
+
+2. Clone this repo recursively.
+3. Build the dependencies under `subprojects`. Follow the instructions on building for Visual C.
+
+   > **Important:** For `libwebsockets`, follow the [instructions on building LWS](https://libwebsockets.org/lws-api-doc-master/html/md_README_8build.html).
+
+4. Generate the CMake cache.
+5. Build the specific executables you want to build, which are defined in `CMakeLists.txt`.
 
 ### macOS/*NIX
 
-1. Clone this repo.
-2. Clone the repositories under `dependencies.txt`, including SDL2.
-3. Build the SDL, SDL_image, and SDL_ttf dependencies using the [build instructions for Linux/UNIX](https://wiki.libsdl.org/SDL2/Installation#linuxunix)
-   or [build instructions for macOS](https://wiki.libsdl.org/SDL2/Installation#macos).
-   > **Note:** You may need to download other tools to build the libraries:
-   > - autoconf
-   > - make
-
-   > **Note:** Clone the submodules under SDL_ttf to download freetype and harfbuzz:
-   >
-   > ```shell
-   > git submodule update --init --recursive
-   > ```
-4. For OpenSSL, simply run:
-   ```shell
-   ./Configure
-   make
-   make test
-   ```
-5. Build the following dependencies first:
-   - `portmidi` (Linux needs [ALSA libraries](https://www.alsa-project.org/files/pub/lib/) to be compiled)
-     - ALSA Lib requires `libtool` to be compiled.
-   - `libwebsockets` (follow the [instructions on building LWS](https://libwebsockets.org/lws-api-doc-master/html/md_README_8build.html))
-6. Build via CMake.
+1. Clone this repo recursively.
+2. Build the dependencies under `subprojects`. Follow the instructions on building for *NIX (macOS should have similar
+   instructions for *NIX).
+3. Generate the CMake cache.
+4. Build the specific executables you want to build, which are defined in `CMakeLists.txt`.
