+## Ubuntu 15.10
+
+The procedure is detailed in the [.travis.yml](.travis.yml).
+
+If you want to reuse distribution packages as much as possible,
+you need at the very least to:
+
+-   compile and install AntTweakBar from source.
+
+    There is no Ubuntu package for it, and that project is marked as unmaintained.
+
+-   compile and install GLFW from source because of a Debian packaging bug with CMake:
+    <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812853>
+
+-   apply the fix at
+    <https://github.com/rougier/freetype-gl/blob/a4cfb9abac19a0ab62b625a9b6f856e032fe3732/.travis.yml#L23>
+    to the installed GLFW files
+
+Then:
+
+    mkdir build
+    cd build
+    cmake ..
+    make
+
+You can then run some demos under:
+
+    cd demos
