+# Scripts to build Epidemic for Android
+
+## Introduction
+
+[Epidemic](https://github.com/sseefried/open-epidemic-game) is a game written for mobile
+devices in Haskell.
+
+This repo contains a script called `build-epidemic-apk.sh` to build the game for Android
+devices using ARMv7 (or compatible) chipsets. The repo contains a thin Java wrapper that
+calls into the natively compiled code of the game.
+
+## Setting up a development environment
+
+This won't just work out of the box. You will require a GHC cross compiler targetting
+ARMv7 and will need to build all the associated libraries. This isn't straightforward at all!
+
+However, I've done all the work for you with the help of Docker. Please see the repo
+[`docker-epidemic-build-env`](https://github.com/sseefried/docker-epidemic-build-env.git)
+for more details.
+
+## Setting up the build script
+
+You will need to create a file called `build-vars.rc`. See
+[`build-vars-rc.example`](https://github.com/sseefried/android-build-epidemic-apk/blob/master/build-vars.rc.example)
+
+You will need to set paths for:
+
+* The [Epidemic](https://github.com/sseefried/open-epidemic-game) repo
+* The Android NDK
+* the directory containing static C libraries that Epidemic requires.
+
+If you have used the `Dockerfile` in the repo
+[`docker-epidemic-build-env`](https://github.com/sseefried/docker-epidemic-build-env.git)
+(mentioned above), then you can just
+
+    cp build-vars.rc.example build-vars.rc
+
+
+## Installing the APK on Android devices
+
+Once you have run the build script you should find the file:
+
+    bin/com.declarative.games.epidemic.beta-debug.apk
+
+You can install this file on your Android device with [`adb`](http://developer.android.com/tools/help/adb.html).
+
+    adb install -r com.declarative.games.epidemic.beta-debug.apk
+
+On your device you will need to tick "Unknown Sources" in "Settings -> Security".
