# Upskilling Material

> **Themelio compatibility reference.** This page describes the retained Themelio implementation or its historical design. Check the [parallel-operation guide](/compatibility/index.md) before applying it to the current platform.

Upskilling Materials are educational articles and tutorials. They come in two types: external links pointing to articles hosted elsewhere, and hosted content written directly on the platform with a rich text editor. Both types share common metadata including domains, tasks, difficulty, languages, and tags.
