 This code repository (or "repo") is designed to demonstrate the best GitHub has to offer with the least amount of noise.
 
 The repo includes an `index.html` file (so it can render a web page), two GitHub Actions workflows, and a CSS stylesheet dependency.

+## 🐳 Docker Image Migration to HelmHubIO
+
+
+This repository automates the migration of Docker images from a source Docker Hub user (e.g. bitnamilegacy) to a destination user (e.g. helmhubio) using GitHub Actions.
+
+The workflow performs the following in sequence:
+1.	Fetch all repositories from the source user on Docker Hub.
+2.	List tags for each repository, filtering out SHA-based tags (e.g. sha256-*).
+3.	Select the most recent valid tag (e.g. 2.4.65-debian-12-r2).
+4.	Check if the image and tag already exist in the destination repository (helmhubio).
+    - If the image exists, it’s skipped.
+	- If not, it proceeds to migrate.
+5.	Pull the image from the source repository.
+6.	Tag and push the image to the destination repository on Docker Hub.
+7.	Continues until all repositories have been processed.
+
+The migration runs manually via GitHub Actions → “Run workflow”.

+
+#### Notes
+
+- The script ensures idempotency — it will not re-upload images that already exist.
+- Non-versioned tags (SHA-style) are automatically skipped.
+- Pagination support ensures all repositories are fetched, not just the first 100.
