 ## Documentation
 
 The documentation can be found on [GitBook](https://mrcmodding.gitbook.io/arma-3-object-builder/home). As the add-on changes, the documentation will be updated.
 
+A series of introductory videos is also in production, and can be found on [YouTube](https://youtube.com/playlist?list=PL1L8e_Shj5DErJinP8vtLTImQ5PY4K9IN&si=U_AGJSK5mSi6VrjG). Videos may or may not exist about every feature, and any particular video might end up outdated as the add-on is developed. The written documentation always takes precedence.

 ## Installation
 
 The add-on can be installed after either downloading a packaged release, or cloning the repository and manually packing it.
