Since the major reason for me learning Git is to use it with Dreamweaver, it may be worth adding a couple of useful links here.
Using Git in Dreamweaver. The latest version of the book, Adobe Dreamweaver Classroom in a Book (2021) has a section on Git and references an Adobe webpage for help in setting up Git in Dreamweaver. The link doesn't work but this is the valid (as of today at least!!) link for that page. Dreamweaver: Working with Git Version Control. This course sounds ideal for using Git with Dreamweaver, but you have to bear in mind that it dates from 2017. In all likelihood, Git will not have changed very much in the last four years, but of course, Adobe tend to make quite radical changes in Dreamweaver over a short period of time, so it is questionnable how relevant this will be in 2021 as I am creating this page. In all likelihood, the information in the course will be really useful, but you will likely have to spend some time working out how to apply this in more recent versions of Dreamweaver.
