-Tutorials
-=========
+This project is currently in **pre-alpha**, and things will break all the time.
+However, feedback at this time is extremely valuble, so you should still try
+it out!
 
-We have tutorials to help you set up The Littlest JupyterHub (TLJH) on any of the
-popular providers (Google, Digital Ocean, Jetstream, etc) or on your own server.
-They should take less than ten minutes to get you to a working JupyterHub!
+Installation
