Extensions

Frontend

Backend

TYPO3 is like Sushi

Extensions extendeverything

Extensions containyour PHP code

Extensions containyour ideas

Inspiring people to share

How to !nd extensions

typo3.org/extensions/

List extensions

Extension details

View !les

Extension manager

Extension details

Read documentation

Look into !les

Security and con!dence

It is very important that you check every detail of an extensionbefore you install.

What if nothing !ts?

Add your own creation

How do you startyour own creation?

Understandextension structure

Install extbase kickstarter

Andstart coding!

Why do I need a kickstarter?

Faster and less errors

The kickstarter does all the boring work

You can focus on your ideas and design

= more fun!

TYPO3 has old and new extension styles
