Looks good

I would ask @geoerika to put the main description back so we can keep the automated SR&ED digest (example) working for next year, once @ashishjullia works out the string parsing problem

Oh yes! I will, once the parsing fix is done. Thank you!

Done, hopefully it won't break in worst case scenarios. :) @ashishjullia thank you!
