We are working on maintaining Sharepoint-Online themes, page layouts, styles (css, html, images from masterpage & siteassets) in git repository & continuous integration of changes to Dev, UAT & Prod environment. This is just the start of Sharepoint work. We will use VSTS for managing all these work. My question is:
1- We have some custom templates (html & css) specific to company & some templates provided by microsoft as part of sharepoint. We were planning to maintain only custom templates in git repository & not microsoft provided templates (because we are not going to change in m/s templates.). Can anyone please suggest whether this as per microsoft guidelines.? Is there any standard documentation provided by microsoft for organizing these files in source control ?
