+# ubox MSX lib
+
+This is a set of libraries and tools to make MSX games using the C programming
+language.
+
+There are three components:
+
+  - **ubox**: thin wrapper around MSX 1 BIOS, focusing on Screen 2 and 32K
+    cartridge ROMs.
+  - **spman**: a simple sprite and pattern manager with flickering support.
+  - **mplayer**: a wrapper around Arkos 2 AKM player, supporting music and
+    priority based one channel sound effects.
+
+The aim is making MSX games in C, without writing Z80 assembler or having a
+deep knowledge of the system.
+
+## Requirements
+
+ - SDCC (3.9.0 recommended)
+ - GNU Make (others may work)
+ - a POSIX compatible environment
+
+If you want to build the example you will also need:
+
+ - python 3
+ - pillow
+ - GCC (only the C compiler)
+
+If you want to build the docs you will also need:
+
+ - pandoc
+ - python 3
+ - pygments
+ - pandocfilters
+
+## Building
+
+To build the libraries run:
+
+    make
+
+After a successful build, the libraries should be in `./lib`.
+
+The include files are ready to use in `./include`.
+
+Add those directories in `SDCC`'s search path and you are ready to go.
+
+### Building the example
+
+An example game is included with the libraries and it can be built with:
+
+    make game
+
+After a successful build, the game ROM should be in `./bin`.
+
+### Building the docs
+
+The documentation is available at
+[usebox.net](https://www.usebox.net/jjm/ubox-msx-lib/), so this is optional.
+
+To build the docs run:
+
+    make docs
+
+The reference in `HTML` format will be generated in `./docs`.
