-FSX DroboApp build scripts
+This is a set of scripts to package a DroboApp from scratch, i.e., download sources, unpackage, compile, install, and package in a TGZ file. The `master` branch contains the Drobo5N version, the `drobofs` branch contains the DroboFS version.
+
+## I just want to install the DroboApp, what do I do?
+
+Check the [releases](https://github.com/droboports/fsx/releases) page. If there are no releases available, then you have to compile.
+
+## How to compile
+
+First make sure that you have a [working cross-compiling VM](https://github.com/droboports/droboports.github.io/wiki/Setting-up-a-VM).
+
+Log in the VM, pick a temporary folder (e.g., `~/build`), and then do:
+
+```
+git clone https://github.com/droboports/fsx.git
+cd fsx
+./build.sh
+ls -la *.tgz
+```
+
+Each invocation creates a log file with all the generated output.
+
+* `./build.sh distclean` removes everything, including downloaded files.
+* `./build.sh clean` removes everything but downloaded files.
+* `./build.sh package` repackages the DroboApp, without recompiling.
