Help
The Help page is opened with the tab of the same name at the top of the Installer window.
The page collects the links people most often go to from Installer: Documentation, YouTube, Telegram (the support chat), Twitter, Dzen and GitHub. A link opens in the default browser of the system. At the bottom of the page is the email address at which you can write to the company.
You can report a problem with the button in the window title — it is available on any page. If Installer behaved differently than expected, attach the records from the Logs page to the message — they show what exactly was happening.
