Apologies I was actually going to link that acronym to [this post](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757) which explains it in a bit more detail: Minimum Working Example, which means basically a code snippet that contains as little code as possible, and allows others to copy/paste it to run on their local machine and replicate your issue.

This helps in three ways:

1. Often your problem disappears when you attempt to construct the MWE, as you strip away unnecessary parts of your code and mode clearly isolate the issue yourself;
2. If others fail to replicate your issue, it can then point to problems with your installation/Julia version/hardware etc.; and
3. Others can play around with different possible solutions much more easily if they can actually run your code.
