+### Software Distribution Guide (Coming soon)
 
 After you’ve created something on Urbit you’ll probably want to share it with other people. This guide walks you through the mechanisms for distributing software over the network.
 
-### Fullstack Development Tutorial: TodoMVC
+### [Fullstack Development Tutorial: TodoMVC (Coming soon)](https://urbit.org/grants/educational-guide-todomvc-urbit-edition)
 
 This tutorial walks you though everthing you’ve learned to date: writing a gall agent in Hoon from scratch, adapting the classic TodoMVC frontend to interface with that gall agent, and then package up the entire application for distribution over the network.
 
-### Graph Store Tutorial
+### [Graph Store Tutorial](https://urbit.org/docs/userspace/graph-store/overview)
 
 Graph store is a gall agent that’s designed to be a general-purpose database for storing graph-like data. Comprising the bulk of the backend for Tlon’s Landscape applciation, it’s battle tested and optimized for real-world use.
