+Bashbot is tagged with version numbers. If you start a new development cycle you can tag your fork with a version higher than the current version.
 E.g. if you fork 'v0.60' the next develop version should tagged as ```git tag "v0.61-dev"``` for fixes or ```git tag "v0.70-dev"``` for new features.
 
 To get the current version name of your develepment fork run ```git describe --tags```. The output looks like ```v0.70-dev-6-g3fb7796``` where your version tag is followed by the number of commits since you tag your branch and followed by the latest commit hash. see also [comments in version.sh](../dev/version.sh)
 
-To update the Version Number in your scripts run ```dev/version.sh```, it will update the line '#### $$VERSION$$ ###' in all files to the current version name.
