Are you thinking of starting with meteor. I am starting learning meteor and thought of writing a series for all those PHP developers to learn meteor. Meteor is a java-script full stack framework. Like when you started with LAMP stack you had Apache, Mysql and PHP glued all together similarly in Meteor JS you have everything .
Meteor installer have Mongo DB installed by default.
I have documented the wiki . Please feel free to add you comments and suggestions to make it more helpful for others PHPers.
