+# Semantic Versionning Bump
+
+Increment your version using this command line tool.
+
+It depends only `zsh` so should be really portable.
+
+## Install
+
+simply put the `bump.sh` script in directory present in your PATH
+and make it executable `chmod ugo+x bump.sh`.
+
+## Examples
+
+~~~
+$ bump.sh 0.14.2 major
+1.0.0
+$ bump.sh 0.14.2 minor
+0.15.0
+$ bump.sh 0.14.2 patch
+0.14.3
+$ bump.sh 0.14.2 qualifier rc1
+0.14.2-rc1
