Installing Chromium on Raspberry Pi without desktop

Start with a Rasbian light version.
Install chromium and x-server

sudo apt-get install chromium-browser
sudo apt-get install xserver-xorg
sudo apt-get install xinit

If you now start chromium-browser it will show the following error:

Failed to put Xlib into threaded mode.

Gtk-WARNING cannot open display

this is because you have to start it with xinit:

xinit chromium-browser

Chromium will start, but you will need a minimal window manager.

sudo apt-get install matchbox-window-manager

Now you need a shell script to start your chromium

sudo nano

Insert the following lines, Exit with ctrl+x, Y and Enter.

matchbox-window-Manager -use_cursor no&
chmod +x

Start it now with:

xinit ./

Add Chromium options as you like. E.g. –Kiosk –allow-running-insecure-content plus your URL
