 ## JS-YAML
 
-Yaml front matter is a wrapper to [js-yaml](https://github.com/nodeca/js-yaml). Therefore yaml front 
-matter supports the same api as js-yaml plus a more so pay [js-yaml](https://github.com/nodeca/js-yaml) a visit. 
-You can directly access js-yaml in the command line by running `$ js-yaml` (note this will run the actual js-yaml 
-parser and will not be able to parse input intended for yaml-front-matter).
+Yaml front matter wraps [js-yaml](https://github.com/nodeca/js-yaml) to support parsing yaml front-matter.
