+# Hibis Game Engine
+Hibis (short for Hibiscus ([named after the genus of flowering plants](https://en.wikipedia.org/wiki/Hibiscus))) is a work in progress game engine written in C++.<br>
+The goal of this game engine is to provide each part of the engine (renderer, audio, physics etc.) in seperate libraries so you can easily make your own system if need be.
+# Install
+## Pre-compiled libraries
+lmao they don't exist yet chill
+## Compiling
+### Note: MSVC
+`MSVC` (Microsoft Visual C++ Compiler) is unsupported and I cannot guarentee that Hibis will compile using it. Please use another compiler like G++ or Ninja instead.
+### Dependencies
+To compile Hibis, you will need:
+- Meson
+- Meson-compatible compiler (recommended: Ninja or ccache + G++)
+- A few minutes of your time
+Each non-core library also has specific dependencies, including:
+- (RSDL) SDL2
+- (RSDL) SDL2_ttf
+Linux users should be able to get all of these (except time) from their package manager.<br>
+Windows users will need to use vcpkg or similar to easily get these dependencies.
+### Actually Compiling
+#### No Customising
+Run `compile.sh` in the folder you cloned Hibis into.
+#### Customising
+In the folder you cloned Hibis into, run `meson build` to create a folder where the magic happens.<br>
+Move into the build directory using CD and you can now use `meson configure` to adjust compile options.<br>
+Once you have configured everything, run `meson compile` in the build directory and it should finish successfully.
