Complete Guide

Things to note

The Library File that you download will always need to exist. Do not Delete it. Lightburn will reference the file and if the file is deleted, so is the library in Lightburn.
If you move the library file, then you will need to Re-Load into Lightburn
You can share a Library over a network or Cloud service but you may get errors if Lightburn cannot connect to the file (say you are remote and offline). Local storage is best
It is best to not leave the Library File in your Downloads folder. Move it to a specific Lightburn folder where you keep other Lightburn stuff

How to Load

If you haven't already downloaded the Library that is appropriate for your machine, go grab it from the Material Libraries and Safe/Unsafe Resources article.
