+# Example Dockerfile to Build Sokoban for AARCH64
+
+## Dependency
+
+This project depends on [SFOSBID](https://codeberg.org/aerique/sfosbid).
+This Git repository needs to be cloned somewhere and then, in the root of
+that project's directory, the following commands should be issued:
+
+- `bin/download.sh`
+- `bin/build.sh`
+
+Once this has been successfully built we can continue with building the
+Sokoban RPM.
+
+## Building the Sokoban RPM
+
+Go to the LQML project's root directory, then:
+
+- `cd examples/sokoban`
+- `docker build -t sokoban -f platforms/sailfish-os/Dockerfile .`
+    - this takes a long time, especially if one is on another architecture
+      than the one being built
+- `docker run -it sokoban`
+
+A message will be displayed on how to copy the RPM out of the running
+container.
+
+## Installing the Sokoban RPM
+
+Get the RPM onto your Sailfish OS phone either by using SSH, by putting it
+online somewhere, emailing it to yourself, etc.
+
+Then either in Downloads, Transfers or using the file manager install the RPM.
+
+There should now be an new icon in your apps menu called "Sokoban".
+
+## Building for other architectures
+
+All relevant command are called with `sb2 -t SailfishOS-latest-aarch64 …`,
+so creating a new Dockerfile or replacing `SailfishOS-latest-aarch64` with
+one of the other installed architectures this project should build for that
+architecture.
+
+Available architectures in [SFOSBID](https://codeberg.org/aerique/sfosbid):
+
+- `aarch64`
+- `armv7hl` (this is the old 32-bit Sailfish OS architecture)
+- `i486`
+
+Building for the other architectures has not been tested.
