 ## Migration Configuration:
-For setting up a migration job, create an `export.json` file with specific data models and operations as detailed in the [full export.json format guide](https://help.sfdmu.com/full-documentation/configuration-and-running/full-exportjson-format).
 
-## Running the Migration Job:
+Set up a migration job by creating an `export.json` file with specific data models and operations, as detailed in the [Full export.json Format Guide](https://help.sfdmu.com/full-configuration).
+
+Here is a basic `export.json` example for upserting Accounts and their related Contacts, assuming unique Name for Accounts and unique LastName for Contacts across source and target orgs:
+
+```json
+{
+    "objects": [
+        {
+            "operation": "Upsert", // Specifies the type of operation: "Update", "Upsert", "Insert", "Delete", etc., as detailed in the full documentation.
+            "externalId": "LastName", // The unique identifier for Contacts, used for upsert operations.
+            "query": "SELECT FirstName, LastName, AccountId FROM Contact", // Defines the fields to transfer from the source to the target during the migration.
+            "master": false // Ensures that SFDMU only processes Contact records related to the specified Accounts.
+        },
+        {
+            "operation": "Upsert", // Specifies the type of operation for Accounts.
+            "externalId": "Name", // The unique identifier for Accounts, used for upsert operations.
+            "query": "SELECT Name, Phone FROM Account WHERE Name = 'John Smith'" // Selects specific Accounts by Name for the operation.
+        }
+    ]
+}
+```
+
+## Migration Execution:
+
 Execute migrations using commands tailored to your source and target, whether they are Salesforce orgs or CSV files:
+
 ```bash
-$ sf sfdmu run --sourceusername source@name.com --targetusername target@name.com
+# Migrate data from one Salesforce org to another
+$ sf sfdmu run --sourceusername source.org.username@name.com --targetusername target.org.username@name.com
+
+# Export data from a Salesforce org to CSV files
+$ sf sfdmu run --sourceusername source.org.username@name.com --targetusername csvfile
+
+# Import data from CSV files to a Salesforce org
+$ sf sfdmu run --sourceusername csvfile --targetusername target.org.username@name.com
 ```
-For CSV data interactions, modify the usernames as required for your specific scenario.
+
+Note: When importing or exporting from/to CSV files, ensure the files are located in the directory containing the `export.json` file. The files should be named according to the API name of the respective sObject, such as `Account.csv`, `Contact.csv`.

+- If you encounter permission issues on MacOS, prepend your commands with `sudo`. Adjust CLI command syntax if using the older SFDX CLI platform.
+- To allow SFDMU to connect to your source and target orgs, ensure you have established a local connection to these orgs using the standard `sf org login web` commands, as detailed in the [Authorize an Org Using a Browser](https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_auth_web_flow.htm) documentation.
