+# PyGWalker Tutorials
+
+This directory contains in-depth, step-by-step tutorials designed to complement the concise scripts in `/examples`.
+While the examples demonstrate specific features quickly, the tutorials focus on **progressive learning**, **real-world workflows**, and **best practices** for using PyGWalker effectively.
+
+### Included
+
+* **`complete_tutorial.ipynb`**
+  A comprehensive beginner-to-intermediate notebook covering:
+
+  * environment setup and initialization
+  * core chart types and interactions
+  * data exploration workflows
+  * real use cases (sales analytics, segmentation, experimentation)
+  * performance tips and recommended patterns
+
+This notebook is output-free to keep the repository lightweight, as interactive PyGWalker cells may generate large HTML payloads.
