Hey guys, i fond this on google : https://github.com/romockee/powerarrow
But i don't know how to config (I'm totally noob at Awesome).
So, if someone can help me please, that would be nice.
what about the wiki?
Definitely check out the wiki first, and try this out: http://awesome.naquadah.org/wiki/My_first_awesome.
Then when you're more comfortable handling the config, try using those files you posted in your own config. If you have problems, check the wiki or google - someone else would almost definitely have had the same one.
