Hello World
On this page you learn how to modify a World before it is deployed to the blockchain.
If you want to learn how to modify a World that is already deployed, see the Extending a World guide.
The examples on this page use the vanilla template. See this page for installation instructions. Most examples are written under the assumption that they are independent, and built on top of a new vanilla template. The exception is filtering data synchronization, because it needs a table that isn't a singleton.
