Cool tool, unsure of the security benefits, and doesn't belong in the training section. Closing for now, feel free to reopen and put it in another section, if there's a strong security benefit to mpm.

Thanks @JakobTheDev for the feedback.

My rationale was that one of the best practice of keeping a system secure is to keep its packages and dependencies up to date. Or at least keep an eye on the available updates.

Which mpm help you do in a user-friendly and centralized way. A great quality of life improvement. Especially with its reporting capabilities (exports to CSV, Json, etc.).

If you agree with my rationale, what would make a great section for this new entry? What do you think of the Tools > Dependency Management?
