Step 1: Understand the geometry
Step 2: Understand the symmetry
Step 3: Construct the gaussian surface
Step 4: Examine the gaussian surface
Step 5: Evaluate the electric flux through the gaussian surface.
Step 6: Evaluate the charge enclosed by the gaussian surface
Step 7: Apply Gauss's law for the result!
