-Currently the script uses pre-existing build products from Jenkins
-that are built on Debian unstable. This makes the build product run on none
-but the latest distributions. A much better choice would be to build e.g.,
-on Debian oldstable, CentOS 6, or Ubuntu Trusty or earlier.
-Examples for building bleeding-edge Qt4 and Qt5 applications on such mature
-build systems can be found at

+The script assumes you have built all of the sigrok subprojects and
+installed them into $HOME/sr (e.g. via the sigrok-cross-linux script).
+
+It also assumes you have built AppImageKit in $HOME. First, install all
+build requirements of AppImageKit (see AppImageKit docs or its
+install-build-deps.sh file). Then:
+
+ $ cd $HOME
+ $ git clone https://github.com/AppImage/AppImageKit
+ $ cd AppImageKit
+
+Apply chdir.patch (required to fix sigrok bug #1300), then build:
+
+ $ patch -p1 < chdir.patch
+ $ ./build.sh
