+.SYNOPSIS
+    Prepares a deployment package for LinkSyncServer.
+
+.DESCRIPTION
+    Copies only the files needed for production deployment to a target folder,
+    excludes development artifacts, and creates a starter .env file.
+    After running, the user should edit the .env file with production secrets
+    and run docker-compose up -d --build in the target folder.
+
+.PARAMETER DeployPath
+    Path to the deployment folder. Will be created if it does not exist.
+
+.EXAMPLE
+    .\deploy.ps1 -DeployPath "..\linksync-deploy"
+    .\deploy.ps1 ..\linksync-deploy
