+# GitHub Actions Setup for Docker Hub Publishing
+
+This repository uses GitHub Actions to automatically build and push the Docker image to Docker Hub whenever changes are made to the repository.
+
+## Setup Instructions
+
+### 1. Configure Docker Hub Secrets
+
+You need to add the following secrets to your GitHub repository:
+
+1. Go to your repository on GitHub
+2. Navigate to **Settings** → **Secrets and variables** → **Actions**
+3. Add the following repository secrets:
+
+- `DOCKER_USERNAME`: Your Docker Hub username
+- `DOCKER_PASSWORD`: Your Docker Hub access token (see below for 2FA setup)
+
+#### For Docker Hub accounts with 2FA enabled:
+
+Since your Docker Hub account uses 2FA, you **must** use an access token instead of your password:
+
+1. **Create a Docker Hub Access Token**:
+   - Log in to [Docker Hub](https://hub.docker.com/)
+   - Go to **Account Settings** → **Security**
+   - Click **New Access Token**
+   - Choose a descriptive name (e.g., "GitHub Actions CI")
+   - Select permissions: **Read, Write, Delete** (for pushing images)
+   - Click **Generate**
+   - **Important**: Copy the token immediately as it won't be shown again
+
+2. **Add the token to GitHub Secrets**:
+   - Use the generated access token as the value for `DOCKER_PASSWORD`
+   - Do **NOT** use your actual Docker Hub password
+
+### 2. Workflow Triggers
+
+The workflow is configured to run:
+- On pushes to `master`, `main`, or `develop` branches
+- On pull requests to `master`, `main`, or `develop` branches (build only, no push)
+- Manually via the GitHub Actions interface
+
+### 3. Tags and Versions
+
+The workflow will automatically create the following tags:
+- `latest` (only for the default branch)
+- `android-28.0.3` (version tag)
+- Branch-specific tags for development
+
+### 4. Manual Trigger
+
+You can manually trigger the workflow:
+1. Go to **Actions** tab in your repository
+2. Select "Build and Push Docker Image"
+3. Click "Run workflow"
+4. Choose the branch and click "Run workflow"
+
+## Docker Hub Integration
+
+The workflow also updates the Docker Hub repository description with the README.md content from this repository, keeping the documentation synchronized.
+
+## Troubleshooting
+
+- Ensure Docker Hub credentials are correctly set in repository secrets
+- Check that the Docker Hub repository exists and you have push permissions
+- Verify the workflow has the necessary permissions to access secrets
+
+## Fix for Issue #3
+
+This GitHub Actions workflow resolves [Issue #3](https://github.com/cuisines/gitlab-ci-react-native-android/issues/3) by automatically keeping the Docker Hub image in sync with the repository changes.

+## Automated Docker Hub Publishing
