I mean ressources, blog, tutorial etc...
Thanks for the shout out. I do release a Sketch file on every new blog I write. On top of those shares, you may find this one useful as a Photoshop user: http://blog.mengto.com/photoshop-users-how-to-switch-to-sketch/
Sketch pushed a online manual live yesterday: http://www.bohemiancoding.com/sketch/help/
Use it to make things.
If you know Photoshop, you'll get the hang of it very fast. I played with it for 1,5h and everything was kind of self-explanatory. Start by downloading some .sketch files and try to understand what's going on.
All of these resources are helpful, but I wish Sketch would just let you change the hotkeys to match PhotoShop. It would instantly make the application that much easier to use.
That's an OSX feature ;)
I'd be happy to answer any questions about using Sketch. nathanm at gmail
