+### External Tools Configuration
+1. In Workday Studio, click *Run* on the menu.
+2. Navigate to External Tools -> External Tools Configurations...
+3. Select *Program*. Click *New launch configuration* (icon in the farthest left position of the External Tools dialog box).
+4. Give the configuration a name. Example: "CLARiNET Production Backup"
+5. For my setup, I placed the CLARiNET executable in my Workday workspace directory.
+6. Select an executable in the Location field. Example: ${workspace_loc}\CLARiNET.exe (`${workspace_loc}` is an external tools variable that will convert to the workspace directory when run.)
+7. Set the Working Directory. Example: ${workspace_loc}
+8. Set the Arguments. Example: CLAR_DOWNLOAD "" "${project_loc}" {environment number} {tenant name} {username} {encrypted password} 
+    `${project_loc}` is an external tools variable that will convert to the project directory. CLARiNET will use the last directory name of the project path as the `Cloud Collection`.
+
+- Run CLARiNET with the "-w" parameter to get the environment number.
+- Run CLARiNET with the "-e" parameter to generate an encrypted password.
