copied!<ol> <li>I understand your friend's point, but I firmly disagree with running (potentially, err, probably) broken development code on a production server. Better, download VirtualBox and set up a VM with the same configuration as the server you deploy to. Use git to create "tags" for each version you deploy so you have useful reference points for "versions" of your website.</li> <li>Look at "git submodules". You almost certainly need to learn what these are, but if you've come from a subversion background you'll probably find them very confusing. Submodules are basically references to other repositories, so you have a soft-link to another project inside your main project. They have to be self-contained in a directory however.</li> <li>I personally like to keep a schema.sql file in my repository (just a blank schema, written in SQL) but I don't think keeping your full database backups in the repository would be a wise thing to do, even though you can. Keep those separate.</li> </ol> <p>If you're new to the whole idea of version control systems, you're probably better off just jumping in with both feet. It will all start to make sense as you go. And of course, by its very nature you're unlikely to do any permanent damage since you can roll back and forth.</p> <p>One firm recommendation: commit frequently. Every time you make a change that works, commit. Smaller commits are much easier to handle than large ones. For example, if you need to undo a broken change, you're much more likely to be able to undo it without removing a heap of working code that was committed at the same time if your commits are atomic.</p>
