+# Embedded ABI for contracts
+
+Currently, the ABIs for `world` and `executor` are embedded in the repo.
+To build them, consider the following:
+
+1. Change directory into `examples/spawn-and-move` at the root of the workspace.
+2. Build the example with `sozo`.
+3. Extract the ABI key only for `world` and `executor`:
+```
+sozo build
+jq .abi ./target/dev/dojo\:\:world\:\:world.json > ../../crates/dojo-world/src/contracts/abi/world.json
+jq .abi ./target/dev/dojo\:\:executor\:\:executor.json > ../../crates/dojo-world/src/contracts/abi/executor.json
+```
