Hi!
This is not an issue.

We published a step-by-step guide to conduct forensic analysis of an iOS device using Docker and MVT. We wrote this guide because people are struggling to analyze iOS devices due to the complexity of the procedure on Linux and the incompatibility of libimobiledevice with the latest iOS versions.

This guide will be updated once the PR #16 is merged and will be referring to the official MVT Dockerfile.

NB: I am the co-author of this guide
