+# Github Actions for smart contracts
+
+A Github Action for smart contracts which:
+- builds the wasm files
+- runs mandos-rs and mandos-go tests
+- does a clippy check
+- provides a report containing details about the smart contracts
+
+## Usage
+
+### Standard build
+
+See [contracts.yml](.github/workflows/contracts.yml)
+This uses fixed versions of rust and vmtools.
+Ignores `eei` checks which allows the contracts to use features which are not live on the elrond mainnet yet.
