+
+Adds the `ERC20Module` to `@latticexyz/world-modules`. 
+This module allows the registration of `ERC20` tokens in an existing World.
+
+Important note: this module has not been audited yet, so any production use is discouraged for now.
+
+```solidity
+import { PuppetModule } from "@latticexyz/world-modules/src/modules/puppet/PuppetModule.sol";
+import { IERC20Mintable } from "@latticexyz/world-modules/src/modules/erc20-puppet/IERC20Mintable.sol";
+import { registerERC20 } from "@latticexyz/world-modules/src/modules/erc20-puppet/registerERC20.sol";
+
+// The ERC20 module requires the Puppet module to be installed first
+world.installModule(new PuppetModule(), new bytes(0));
+
+// After the Puppet module is installed, new ERC20 tokens can be registered
+IERC20Mintable token = registerERC20(world, "myERC20", ERC20MetadataData({ decimals: 18, name: "Token", symbol: "TKN" }));
