I mean ressources, blog, tutorial etc...
Sketch pushed a online manual live yesterday: http://www.bohemiancoding.com/sketch/help/
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/
Use it to make things.
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 ;)
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.
Thanks guys for your useful answers!
I'd be happy to answer any questions about using Sketch. nathanm at gmail
