This document provides instructions for using Mule applications to facilitate communication between on-premises systems and Salesforce, allowing data to be shared and automated processes enabled. It outlines steps to create a sample Mule application that reads contact records from a CSV file, processes the data, and inserts the records into a Salesforce org. The application demonstrates how independent systems can integrate by polling an input folder, depositing processed files to an output folder, and adding new contacts visible within the Salesforce contact tab.
