If you wish to contribute, joining the TYPO3 slack workspace is recommended as it is the projects chosen platform for communication. In order to join the slack workspace, you must already have your typo3.org account and then Register for TYPO3's Slack Platform.
On that page, you will also find information about recommended channels.
#typo3-cms-coredev is your channel of choice for core development
#typo3-cms is for general support issues
#random if you are not sure which channel to use or have a general question
You do not need to ask for permission when asking a question. Ask your question directly in the channel and wait for a response.
As always, make sure to follow the Code of conduct or the short form: be nice, be helpful!
Botty on Slack¶
Also the TYPO3 slack bot. We will show you some of its commands later in this manual.
You cannot use Botty in your private channel or in a direct messaging channel with someone else. Botty will only be available in a public channel, to which it has been invited (which is the case in #typo3-cms-coredev).
