First thanks for your opensource work on drone, its really straightforward to configure and easy to use !
Quick question, i remember read some documentation over here about the slack plugin but it now unavailable, is there a special reason ?
this is because http://readme.drone.io/setup/overview no longer exists. It is being served from your browser cache, and the links in the cached page’s sidebar no longer exist either. Unfortunately amazon s3 has very aggressive caching policies which causes issues whenever we make major updates to the documentation.
the best way to resolve this is to purge your browser cache for readme.drone.io or browse the site with developer tools open and the disable cache button checked. Eventually we’ll move away from S3 to avoid this problem, but it is not an immediate priority.
