+## Getting Started for New Clients
+
+This section guides new clients through setting up the Data Migration Accelerator for their own projects.
+
+### Repository Setup: Fork the Repository
+
+Forking creates a copy under your GitHub organization while maintaining a connection to the original repository for future updates.
+
+#### Step 1: Fork the Repository
+
+1. Navigate to the original repository on GitHub
+2. Click **Fork** in the top-right corner
+3. Select your organization as the destination
+4. Uncheck "Copy the `main` branch only" if you want all branches
+
+#### Step 2: Clone Your Fork
+
+```bash
+git clone https://github.com/YOUR_ORG/data-migration-accelerator.git
+cd data-migration-accelerator
+```
+
+#### Step 3: Configure Upstream Remote
+
+```bash
+# Add the original repository as "upstream"
+git remote add upstream https://github.com/thisisqubika/data-migration-accelerator.git
+
+# Verify remotes
+git remote -v
+# origin    https://github.com/YOUR_ORG/data-migration-accelerator.git (fetch)
+# origin    https://github.com/YOUR_ORG/data-migration-accelerator.git (push)
+# upstream  https://github.com/thisisqubika/data-migration-accelerator.git (fetch)
+# upstream  https://github.com/thisisqubika/data-migration-accelerator.git (push)
+```
+
+#### Step 4: Create a Client Branch
+
+Keep your customizations separate from `main` for easier upstream merges:
+
+```bash
+git checkout -b client/your-company-name
+```
+
+### Pulling Upstream Updates
+
+When the original accelerator has updates you want to incorporate:
+
+```bash
+# Fetch upstream changes
+git fetch upstream
+
+# Merge upstream main into your branch
+git checkout main
+git merge upstream/main
+
+# Push updated main to your fork
+git push origin main
+
+# Rebase your client branch on updated main
+git checkout client/your-company-name
+git rebase main
+```
+
+### Contributing Back
+
+If you make improvements that could benefit others:
+
+1. Create a feature branch from `main`
+2. Make your changes
+3. Push to your fork
+4. Open a Pull Request to the upstream repository
+
+### Post-Setup Checklist
+
+After forking the repository:
+
+- [ ] Update `databricks.yml` with your bundle name
+- [ ] Configure GitHub Secrets for CI/CD (see [GitHub Secrets](#github-secrets-for-cicd))
+- [ ] Set up Databricks Secrets scope (see [Databricks Secrets](#databricks-secrets))
+- [ ] Configure cluster environment variables (see [Cluster Environment Variables](#cluster-environment-variables))
+- [ ] Update `env.example` with your default values
+- [ ] Create the required Databricks group (`DEVS_GROUP`)
+- [ ] Test the deployment pipeline
