This will do better if you add more pictures.
Go to https://imgsafe.org upload a pic ( you don't need login) then click on the pic after its uploaded. It will open a window. Copy the link and paste it into your post. ( it will show up automatically of the link is there.)
Then add headers
Go through your subtitles and put ** just to the left and just to the right of each title. This will bold the titles.

Good luck !
