 ## Development Instructions
 
+### Installing dependenecies
+FGGL depends on a few dependencies to work correctly.
+
+On Ubuntu:
+```bash
+sudo apt install build-essential cmake
+sudo apt install -y libglm-dev libglfw3-dev libopenal-dev libspdlog-dev libfreetype-dev libyaml-cpp-dev libassimp-dev libbullet-dev
+```
+On Fedora:
+```bash
+sudo dnf install -y glm-devel glfw-devel openal-soft-devel spdlog-devel freetype-devel yaml-cpp-devel assimp-devel bullet-devel gcc gcc-c++ cmake gtest-devel doxygen lua lua-devel gmock gmock-devel
+```

 ### Building
 It's designed to be a fairly standard cmake project, so the standard cmake steps should work:
 
@@ -18,7 +31,34 @@ project that will build the project and run the demo project in gdb.
 Most of the dependencies should be downloaded automatically. If you're on X don't use glfw from the
 Fedora repos, it won't work (it's configured for Wayland). The version the project builds should work.
 
-### Useful Tools
+### Deploying
+The library is designed to be used as a shared library, as it is licenced in the LGPL. You can generate the shared library, header files and assoicated cmake files using the following command:
+
+```bash
+cmake --install build --prefix /tmp/fggl-lib
+```
+
+This will place the files in /tmp/fggl-lib, you can adjust this to suit your needs.
+
+You can then include the library in your application using cmake, eg:
+
+```bash
+find_package(spdlog REQUIRED)
+target_link_libraries(game spdlog::spdlog)
+
+find_package( fggl REQUIRED PATHS /tmp/fggl-lib )
+target_link_libraries(game fggl::fggl)
+```
+
+### Flatpak Demo
+
+This is still experimental, but the command used to test flatpak compatablity with the demo application is:
+
+```
+flatpak-builder builds/flatpak build-aux/com.fossgalaxy.fggl.demo.yml --force-clean --install --user
+```
+
