+#+title: Collaboration
+
+Imugi can be easily built without any local chicken scheme installation by using the devcontainer spec included in this repository.
+
+* Using the Devcontainers CLI
+First, run ~npm install -g @devcontainers/cli~ to install the devcontainers CLI tool.
+
+This requires a working Docker installation, the steps to which can be found [[https://docs.docker.com/engine/install/][here]]. Also assign your user to the ~docker~ group to avoid having to use ~sudo~ with docker and devcontainer commands.
+
+Once both of the above are installed, the devcontainer can be started with ~devcontainer up --workspace-folder .~ in the repository root. This will build a Debian Trixie container including all Chicken dependencies, and also build Raylib as a static library. We prefer to build with static linking in order to make distribution less annoying.
+
+Once the devcontainer is running, enter it with ~devcontainer exec --workspace-folder . bash~. This will put you at the repository root.
+
+* Dependencies
+The ~deps.lock~ file contains the versions of eggs used in this repository. They can be installed with ~chicken-install -from-list deps.lock~.
+
+* Collaborating with Emacs
+The ~.dir-locals.el~ file automatically sets the Geiser Scheme implementation to Chicken, for any Scheme source file in this directory.
+
+* Running Tests & Samples
+From the ~build~ directory, run ~csm -program <module> ..~ to build a particular module, the ~./<module>~ to run it.
+
+Any module defined in the ~samples~ or ~test~ directory can be run like this, either to show an example game or to run tests for a particular engine module.
+
+ If you are running the devcontainer on an X11 Linux host, running the compiled module should forward the window to your hosts X11 display. YMMV for Wayland and non-Linux hosts.

 Imugi is a framework for building games (primarily tactics games) with Chicken Scheme and raylib. The end goal of this framework is to create a game, also called Imugi, and release to show the capability here.
 
+* Installation & Usage
+Raylib must first be installed before you can get started with Imugi.
+
+Note: this guide assumes static linking for the Raylib library.
+
+Install raylib statically using the following commands:
+#+begin_src shell
+  git clone --depth 1 https://github.com/raysan5/raylib.git raylib
+  cd raylib/src/
+  make PLATFORM=PLATFORM_DESKTOP
+  make install
+#+end_src
+
+The following dependencies are required on Debian:
+#+begin_src shell
+  apt install -y libasound2-dev libx11-dev libxrandr-dev libxi-dev libgl1-mesa-dev libglu1-mesa-dev libxcursor-dev libxinerama-dev libwayland-dev libxkbcommon-dev
+#+end_src
+
+Once raylib is installed, run ~chicken-install -s~ in this directory to install all dependencies and the Imugi egg itself.
+
+You can then import the Imugi modules required in your project.
+
+When building your project, use the flags specified in ~all.options~ in this repository, which includes are the dependency links necessary.
+
 * Architecture
 Imugi is an ECS engine.

 ~create-window~ creates a window using the window parameters described above, sets the target frames per second, then enters a loop which runs the ~process:~ function (~next-frame~ by default) on each frame, unless ~close-predicate:~ (Raylib's ~window-should-close~ function by default) returns true, in which case the window is closed.
