MLED is basically Slackware under the hood, with a bunch of extra packages and a few minor configuration tweaks, so make sure you’re comfortable with the official Slackware Linux documentation.
If you are not familiar with Slackware, head over to the Slackware Documentation Project and read at least the following two articles in the section Getting Started with Slackware:

- Microlinux Enterprise Desktop 14.2 Migration Guide
- Microlinux Enterprise Desktop 14.1 Installation Guide

Read everything carefully. The bits you skip will come back and bite you. :o)
