View source for Developing an MVC Component/Upgrading to Joomla4

=== Further Reading === <!--T:7-->
You can find [https://blog.astrid-guenther.de/en/der-weg-zu-joomla4-erweiterungen/ here] a tutorial for Joomla 4 component development, similar to this Joomla 3 one, and some excellent Joomla 4 documentation is also available [https://www.dionysopoulos.me/book.html here]. Both of these references include descriptions of Joomla 4 impacts on development of other types of Joomla extensions (plugins, modules and templates), which aren't covered here.

This step doesn't cover everything required to update a component from Joomla 3 to Joomla 4, just the aspects covered by the tutorial code. If you're upgrading your own Joomla 3 component then you may find it helpful to look at [[Potential backward compatibility issues in Joomla 4]].
