+
+Helper library to send bundle requests with the Mev-Share protocol.
+
+#### Example usage
+
+```solidity
+import "suave-std/protocols/MevShare.sol";
+
+contract Example {
+    function example() {
+        Transactions.Legacy memory legacyTxn0 = Transactions.Legacy({});
+        bytes memory rlp = Transactions.encodeRLP(legacyTxn0);
+
+        MevShare.Bundle memory bundle;
+        bundle.bodies = new bytes[](1);
+        bundle.bodies[0] = rlp;
+        // ...
+
+        MevShare.sendBundle(bundle);
+    }
+}
+```

 ## Forge integration
 
 In order to use `forge`, you need to have a running `Suave` node and the `suave` binary in your path.
