We have a few support channels you can use to clarify doubts and solve issues.
Check the documentation, here we have a lot of information about how you can use the CLI and the platform, and we have project examples and integration with third-party services
We also have a documentation for our API. If you want to build something on top of our platform you will find a lot of information about it there.
We have many GitHub repositories for almost every service or product we have. You can create issues in that repositories and the team and the community will help you as soon as possible. Some repositories you can access are now-cloud, now-cli, now-desktop, now-client, next.js, hyper, pkg, micro and more.
Our community's Slack, there you can ask for help and either the community and the ZEIT Team will answer and help you solve any doubt you could have. You can access it by going to zeit.chat.
You can use Twitter to send us a DM or mention to @zeithq and a team member will contact you and help you with anything.
The last but not least support channel is our firstname.lastname@example.org email. If you have very custom questions or related to private information (eg. billing issues) you don't want to share in Slack or you like more to use email you can contact us and we happily will help you as far as we could.
