Lightroom Classic and Lightroom CC?

[culman]

I´m working in Classic mode and it confuses me when I get mails about new tutorials in CC-mode, What is the differens, can I have both on my computer an edit pictures from the same library?

Just keep using the Lightroom you know. Lightroom CC is a different application. While it shares a lot of options with Lightroom Classic and could be used together with Lightroom Classic, it is not advised to do that unless you know exactly what you are doing and why.

I agree with Johan, there is a lot of info available. See the article below.
