Hello,
Thank You so much for the Kind Words. :)
Since Canvas is a Static HTML5/CSS3 Template, you will need Some Basic Knowledge HTML and CSS to Edit the Templates using a Text Editor like Sublime Text, Notepad++ or any other Equivalent Editor.
The Best Way to Edit Canvas is to use the Default Templates provided in the Package/HTML Folder and Edit the Content following the HTML Structure as explained in the Documentation > Start > HTML Structure Section. Go Slow! Change One Component at a Time, Check out the Changes Live on your Browser and then Change another Component. We have used Organised Code Structures so that you do not face difficulties Editing the Templates.
You should Consider checking out the Documentation: http://support.semicolonweb.com/canvas-html-documentation/ for Better Understanding of the Features included with the Template.
If you face any issues, do let us know here and we will surely help you out with them! :)
