Semantic versioning

Chances are, if you are writing software, you have some dependencies on other peoples code. There is no reason to reinvent the wheel, so you use the code someone else wrote. One of your options is to copy paste it, but then you won’t get any updates if they release a new version. This is where dependency managers come into play. With a set of instructions, they retrieve the needed dependencies for you, and allow you to lock into specific versions, and update when you want. Before we head into dependency managers, lets first talk about semantic versioning (semver).
