 # GlutSTBMiniAudio-Template
 
-To compile the project
+## Changing the Project Name
+
+In the CMakeLists.txt file, find line 11 (`project(GSM_TEMPLATE LANGUAGES C CXX)`) and replace "GSM_TEMPLATE" with whatever you'd like
+
+## Setup
+
+### For Windows
+1. Install Visual Studio <br>
+Make sure you have installed Visual Studio, not Visual Studio Code, you need the MSVC Compiler installed which is bundled and accessible with Standard Visual Studio
+
+2. Open the Visual Installer<br>
+![](docs/images/CMAKE_TUTORIAL_WIN_STEP1.png "Open Visual Studio Installer")
+
+3. Modify your Visual Studio Installation<br>
+![](docs/images/CMAKE_TUTORIAL_WIN_STEP2.png "Modify Visual Studio with the Installer")
+
+4. Make sure "Desktop Development wiht C++" is installed<br>
+![](docs/images/CMAKE_TUTORIAL_WIN_STEP3.png "Desktop Development wiht C++ must be installed")
+
+5. Once installed open Visual Studio and select "Open a folder", then find and select the folder of this project
+![](docs/images/CMAKE_TUTORIAL_WIN_STEP4.png "Open a Folder")
+
+6. When the project opens, CMake should immedately start installing thirdparty dependencies. Please make sure you see *"CMake generation finished"* before continuing.
+![](docs/images/CMAKE_TUTORIAL_WIN_STEP5.png "CMake generation finished")
+
+7. Finally select the correct Target from the Target list, to the right of the run button. 
+![](docs/images/CMAKE_TUTORIAL_WIN_STEP6.png "CMake generation finished")
+
+8. Finally press the run button and the application should just work
+
+
+### For MacOS
+
+1. There are many different ways to use CMake on Mac or Linux.  Visual Studio works great, but its a [Command Line Interface](#CLI) application so it's easy to use anywhere.<br>
+However, for this guide, install Visual Studio Code and [Brew](https://brew.sh).  Brew is like apt for MacOS, if you don't want to install it, find some way to install CMake.
+
+2. Open this project in Visual Studio Code.
+3. In the extensions tab, find and install "CMake Tools"
+![](docs/images/CMAKE_TUTORIAL_MAC_STEP3.png "CMake Tools Extension")
+4. You may need to reload the project, so do that with CMD+Shift+P, search for *"Reload Window"*, and Press *enter*
+5. When the project opens, it should immediately start downloading the libraries that this project needs.  Please wait until it completes or you see *"CMake generation finished"* in the console.
+6. Once CMake has finished configuring, press Shift+F5 (You may also need to press fn depending on how your mac is setup), and the application will run.
+
+
+### For Linux (Debian/Ubuntu)
+
+The following packages are needed in order for the included libraries to function: cmake, build-essential, libgl1-mesa-dev, libglu1-mesa-dev, freeglut3-dev, libx11-dev, libxcursor-dev, libxtst-dev, libxft-dev, libxmu-dev, libxi-dev
+
+
+Heres an easy one-line install script
 ```
-cmake .; make; ./GSM_TEMPLATE
+sudo apt install cmake build-essential libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev libx11-dev libxcursor-dev libxtst-dev libxft-dev libxmu-dev libxi-dev -y
+```
+
+After this point, follow the same instructions for MacOS, or use the CLI Interface below.
+
+*NOTE* - For some reason, unix needs to use #include `<GL/freeglut.h>`, it will thow a error if #include `<gl/freeglut.h>`.  Notice the capitalization
+
+
+
+### CLI
+To compile the project with normal cmake, it's stupid easy.
+```
+cmake .; make;
+```
+The binary should be in the root of the project after it is installed so run 
+```
+./GSM_TEMPLATE
 ```
