A.gitignore file is a great and simple tool we can use to prevent including unwanted files in a git repository. This file can be used to simply ignore files and directories but also be used to create complex rules and partial rules to ignore select files.

In this video GitGuardian developer advocate, Mackenzie, runs through exactly how to get started with both a local and a global.gitignore file and shows exactly how the file works. This is designed as an introduction so that you have the knowledge to understand more complex uses for the.gitignore files.
