+
+## 1. Toolchain
+Since the project uses `CMake` and `git`, you'll need to install them! If you don't have them, you can do the following:
+
+```bash
+pkg_add cmake git
+```
+
+Once that's done, check the version of CMake!
+
+```bash
+cmake --version
+cmake version 3.25.2
+```
+
+If your CMake version is not as shown above then don't worry! You can still follow along, even if you're ahead or behind!
+
+## 2. Install Voice Dependencies (Optional)
+If you wish to use voice support, you'll need to do the following:
+
+```bash
+pkg_add libsodium opus pkgconf
+```
+
+## 3. Create a CMake project
+
+In an empty directory, create the following files and directories:
+
+\dot
+digraph "Example Directory" {
+	graph [ranksep=1];
+	node [colorscheme="blues9", fontname="helvetica"];
+
+	"Your Directory" [style=filled, color=1, shape=rect]
+
+    	subgraph cluster_0 {
+		style=filled;
+		color=lightgrey;
+		node [style=filled, color=2, shape=rect]
+		build;
+		libs;
+		src;
+		"CMakeLists.txt";
+		label = "The main area for your bot's files.";
+	}
+
+	subgraph cluster_1 {
+		style=filled;
+        	color=lightgrey;
+        	node [style=filled, color=3, shape=rect]
+        	"DPP";
+        	label = "Where the DPP source is.";
+	}
+
+	subgraph cluster_2 {
+		style=filled;
+        	color=lightgrey;
+        	node [style=filled, color=3, shape=rect]
+        	"main.cpp";
+        	"more code...";
+        	label = "This is where your bot's code will go.";
+	}
+
+	"Your Directory" -> build;
+	"Your Directory" -> src;
+	"Your Directory" -> libs;
+	"Your Directory" -> "CMakeLists.txt";
+
+	libs -> "DPP";
+
+	src -> "main.cpp";
+	src -> "more code...";
+}
+\enddot
+
+## 4. Downloading Source
+Inside your `libs` folder, you'll want to clone the latest from the github repo. You can do this by running the following command `git clone https://github.com/brainboxdotcc/DPP.git`.
+
+## 5. Configure CMake
+
+You'll need to modify the `CMakeLists.txt` to tell CMake what it's looking for, and other information.
+
+Here is an example CMake configuration, you can adapt it according to your needs:
+
+~~~~~~~~~~~~~~cmake
+# Minimum CMake version required, we'll just use the latest version.
+cmake_minimum_required (VERSION 3.25)
+
+# Project name, version and description.
+project (discord-bot VERSION 1 DESCRIPTION "A discord bot")
+
+# Add DPP as dependency.
+add_subdirectory(libs/DPP)
+
+# Add source to this project's executable.
+add_executable (${PROJECT_NAME} 
+	src/main.cpp
+)
+
+# Link the DPP library.
+target_link_libraries(${PROJECT_NAME}
+	dpp
+)
+
+# Specify includes.
+target_include_directories(${PROJECT_NAME} PRIVATE
+	libs/DPP/include
+)
+
+# Set C++ version.
+set_target_properties(${PROJECT_NAME} PROPERTIES
+	CXX_STANDARD 17
+	CXX_STANDARD_REQUIRED ON
+)
+~~~~~~~~~~~~~~
+
+## 6. Build the bot.
+
+Now that we have our all our cmake stuff setup and we've got our code in place, we can initalise CMake. You'll want to go inside the `build/` directory and do `cmake ..`. 
+
+Once that's completed, you'll want to head back to your up-most folder (where all the folders are for your bot) and run `cmake --build build/ -j4` (replace -j4 with however many threads you want to use). This will start compiling your bot and creating the executable.
+
+After that has finished, you can head into `build/` and run your bot by doing `./discord-bot`! If everything went well, you should see your bot come online!
+
+**Have fun!**
