This program doesn't have much too it, but it is exactly what you need. Ectomorphs can't and shouldn't have any workout routines that take more than 1 hour, and you want as many compound lifts as possible. If you're looking to gain weight, you want 3 full body workouts per week with no back to back workout days. Bench presses, overhead presses, squats, deadlifts, etc. will do you wonders.
Why would an ecto want to do full body workouts?
I've found the best thing to do is sticking to basic exercies
Squats, Deadlifts, Pull-Ups, Bent Over Rows, Military Presses, Incline Bench Presses, Flat Dumbbell Bench Presses, Dips, Curls.
High Reps, Heavy Weight. High Calories, High Protein, High Carbs, Moderate Fat.
Doing all those complex programs with complex exercises and movements over the years was a huge waste of my time.
