+## Render Pipeline Samples
+
+The samples are not included in this repository to keep the size small.
+
+#### Automatic Download (recommended)
+You can run `python download_samples.py` to automatically download the samples.
+
+#### Manual Download
+If you want to manually download the samples (for whatever reason), you can
+find them here:
+<a href="https://github.com/tobspr/RenderPipeline-Samples
+">https://github.com/tobspr/RenderPipeline-Samples</a>
+
+After downloading, place the downloaded contents in this folder to run the samples.
