+**Important note**: if you are building using WSL, `lektord` will likely not
+launch, because `XDG_RUNTIME_DIR` is not defined here. This folder is
+important, this is where most of your deamons are puttings theirs sockets and
+so. Blame Microsoft for that. A workaround is to export one: `export
+WDG_RUNTIME_DIR=$(mktemp -d)` before launching lektord. Be aware that you will
+have issues with sound and videos becouse you will need to set up a X server...

 Currently, supported compilers are: `icc` 19.1.2.254 and above, `gcc` 8.3.0 and
 above, `clang` 7.0.1 and above. It compiles on debian, thus it must compiles on
 your system (apport from CentOS, because I never tested on it).
