Should I start using flexbox?

Question

css

We got our hands on flexbox. And nothing is clear. As I understand it, in the development process there were several syntaxes for them. Currently, only the latest browsers support the latter.
Is it possible to teach older sites not to fall apart? I found flexie, but they warn that it worked with 2009 syntax.
And where are the latest materials on it? Whatever way different implementations.

You can start, but on projects whose audience has updated browsers.
Or make an additional old layout through float and connect if Modernizr says that Flexbox is not supported.
