+## Note on .NET SDK and Node.js
+
+While .NET SDK and Node.js installation scripts are available in the `src/_archive/scripts/` directory, we recommend using GitHub Actions' official setup actions for these tools in your workflows:
+
+- **Node.js**: Use [`actions/setup-node`](https://github.com/actions/setup-node)
+- **.NET SDK**: Use [`actions/setup-dotnet`](https://github.com/actions/setup-dotnet)
+
+These official actions provide better caching, version management, and are optimized for CI/CD environments.

+# Archived Scripts
+
+This directory contains installation scripts that have been archived in favor of using GitHub Actions' official setup actions.
+
+## Archived Scripts
+
+### Node.js Installation (`scripts/install-nodejs.sh`)
+- **Replaced by**: [`actions/setup-node`](https://github.com/actions/setup-node)
+- **Reason**: The official action provides better caching, version management, and is optimized for CI/CD
+
+### .NET SDK Installation (`scripts/install-dotnet-sdk.sh`)
+- **Replaced by**: [`actions/setup-dotnet`](https://github.com/actions/setup-dotnet)
+- **Reason**: The official action handles multiple SDK versions, caching, and is maintained by Microsoft
+
+## Usage
+
+These scripts are preserved for reference and can still be used if you need to install these tools directly in the Docker image. However, for GitHub Actions workflows, we recommend using the official setup actions.
+
+### Example workflow usage:
+
+```yaml
+steps:
+  - uses: actions/checkout@v4
+  
+  - name: Setup Node.js
+    uses: actions/setup-node@v4
+    with:
+      node-version: '20'
+      cache: 'npm'
+  
+  - name: Setup .NET
+    uses: actions/setup-dotnet@v4
+    with:
+      dotnet-version: |
+        8.0.x
+        9.0.x
