Continuous Integration (CI) is a way of making sure that the code from many different people all works together. It helps us make sure our software works in the way we want it to.
Think of it like this: We have different people writing different pieces of a puzzle, but in order for the puzzle to be completed, all the different pieces have to fit together.
That's what CI does: it makes sure that all the pieces fit together and work together. We can run tests to make sure that when the pieces are put together, the software does what we expect it to. It helps us catch any issues early on in the development process and fix them before it's finished.
