In order to generate slugs from our post's titles, we will use the underscore-string library, which comes with a simple slugify() function. Luckily, a wrapper package for this library already exists on the Meteor package servers. To add it, we run the following command from the terminal in our my-meteor-blog folder:

$ meteor add wizonesolutions:underscore-string

This will extend underscore, which is used by default in Meteor, with extra string functions such as _.slugify(), to generate a slug from strings.
