 ## Deep Dive
 
-In April 2019, Francisco Javier López hosted a [Deep Dive] on GitLab's [Git LFS] implementation to share his domain specific knowledge with anyone who may work in this part of the code base in the future. You can find the [recording on YouTube], and the slides on [Google Slides] and in [PDF]. Everything covered in this deep dive was accurate as of GitLab 11.10, and while specific details may have changed since then, it should still serve as a good introduction.

+on GitLab's [Git LFS](../topics/git/lfs/index.md) implementation to share his domain
+specific knowledge with anyone who may work in this part of the code base in the future.
+You can find the [recording on YouTube](https://www.youtube.com/watch?v=Yyxwcksr0Qc),

+and in [PDF](https://gitlab.com/gitlab-org/create-stage/uploads/07a89257a140db067bdfb484aecd35e1/Git_LFS_Deep_Dive__Create_.pdf).
+Everything covered in this deep dive was accurate as of GitLab 11.10, and while specific
+details may have changed since then, it should still serve as a good introduction.
