# Migrating from GTK 2.x to GTK 4 {#gtk-migrating-2-to-4}

If your application is still using GTK 2, you should first convert it to GTK 3,
by following the [migration guide](https://developer.gnome.org/gtk3/stable/gtk-migrating-2-to-3.html)
in the GTK 3 documentation, and then follow [these instructions](#gtk-migrating-3-to-4).
wip: Include markdown content, via pandoc Use pandoc to convert freestanding markdown files to docbook for inclusion in the generated docs, and use bits and pieces of gtk-doc code to continue expanding typical gtk-doc abbreviations. The new tool for markdown -> docbook is a python script called gtk-markdown-to-docbook. The markdown dialect is specified via a list of pandoc extension in gtk-markdown-to-docbook. It includes header annocations, definition lists and tables, among other things. This commit converts the 3 overview chapters (drawing, input handling and actions) and the migration guide to markdown syntax. Other files that are still listed in content_files can be converted later. This commit adds a pandoc dependency. 2020-05-23 01:56:39 +00:00			`# Migrating from GTK 2.x to GTK 4 {#gtk-migrating-2-to-4}`
