Catechesis
For the moment, you can find two catechisms here to help you with catechesis. (You can find out about them and about why catechesis is so important here.) But, in the future, this is where you'll be able to find a range of catechetical resources to help pass on the faith and make disciples.
I'm slowly working through the Tenet Catechism making short teaching videos which you can find here.
