11th edition

I'm asking for a little help going into 11th, ive collected ad mech and Tau. Ive very much neglected my followers of the machine god, 11th is going to be their breakthrough for my LGS however im very bad at making lists. I really wanna include my Robots but I haver zero idea on how to build around them or what units may help cover their weaknesses. Does and fellow tech priests have any tips for ad mech list building? Like what are some auto includes and what are some good units that may support the kastellans weaknesses. Ive been thinking about adding an imperial knight, but thats alot of points just the knight and the robots. I apologize if this seems a bit rambling like.
