+[profile.default]
+src = "src"
+out = "out"
+libs = ["lib"]
+evm_version = 'shanghai' # Kakarot Sepolia supports `PUSH0`
+
+[rpc_endpoints]
+kakarot_sepolia = "https://sepolia-rpc.kakarot.org"
+```
+
+### Fork Testing
+
+```shell
+$ forge test --fork-url "https://sepolia-rpc.kakarot.org"
+# or $ forge test --fork-url kakarot_sepolia
+```
+
+### Deployment
+
+You can use the deploy script to deploy contract:
+
+```shell
+$ forge script ./script/Deploy.s.sol --broadcast --rpc-url "https://sepolia-rpc.kakarot.org"
+# or $ forge script ./script/Deploy.s.sol --broadcast --rpc-url kakarot_sepolia
+```
+
+or directly use the [forge command](https://book.getfoundry.sh/reference/forge/forge-create):
+```shell
+$ forge create <path-to-contract>:<contract-name> --rpc-url "https://sepolia-rpc.kakarot.org" --private-key <your_private_key>
+# or $ forge create <path-to-contract>:<contract-name> --rpc-url kakarot_sepolia --private-key <your_private_key>
