 # Mines
+
+This is a work-in-progress Android implementation of the single-player puzzle
+video game, "Minesweeper." The code aims to emulate the gameplay of Microsoft
+Minesweeper. (Within reason, of course. It would be very difficult to implement
+chording with the input vocabulary of a mobile device.)
+
+Mines is free software: you can redistribute it and/or modify it under the terms
+of the GNU General Public License as published by the Free Software Foundation,
+either version 3 of the License, or (at your option) any later version.
+
+Mines is distributed in the hope that it will be useful, but WITHOUT ANY
+WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A
+PARTICULAR PURPOSE. See the GNU General Public License for more details.

+Mines. If not, see <https://www.gnu.org/licenses/>.
+
+## Building
+
+Assuming that you have the Android SDK properly installed and configured, Mines
+can be built with the following command:
+
+```sh
+./gradlew assembleRelease
+```
+
+This will produce `app/build/outputs/apk/release/app-release-unsigned.apk`. This
+file will need to be signed with `jarsigner` and optimized with `zipalign`
+before it can be installed on an Android device.
