 To create an offchain attestation, you can use the `signOffchainAttestation` function provided by the Offchain class in the EAS SDK. Here's an example:
 
 ```javascript
-import { SchemaEncoder } from "@ethereum-attestation-service/eas-sdk";
+import { EAS, SchemaEncoder } from "@ethereum-attestation-service/eas-sdk";
+
+// Initialize EAS with the EAS contract address on whichever chain where your schema is defined
+const eas = new EAS(EASContractAddress);
 
 const offchain = await eas.getOffchain();
 
 // Initialize SchemaEncoder with the schema string
+// Note these values are sample values and should be filled with actual values
+// Code samples can be found when viewing each schema on easscan.org
 const schemaEncoder = new SchemaEncoder("uint256 eventId, uint8 voteIndex");
 const encodedData = schemaEncoder.encodeData([
   { name: "eventId", value: 1, type: "uint256" },
