 # Pens & Pencils (Tabular)
 
-## Features (5)
+This dataset contains real-world measurements of pens and pencils collected manually,
+with augmentation for experimentation in ML education.
+
+## Features (6)
 - **length_cm** (float)
 - **weight_g** (float)
 - **is_metallic** (0/1)
-- **body_shape** (string; e.g., round/hexagonal/triangular/other)
-- **is_pen** (binary target, 1=pen, 0=pencil)
+- **body_shape** (categorical; e.g., round, hexagonal, triangular)
+- **has_clip** (0/1)
+- **is_pen** (binary target; 1 = pen, 0 = pencil)
 
 ## Splits
 - `original`: 30 manually measured rows (≥30)
 - `augmented`: 300 synthetic rows (≥300), label-preserving jitter on numeric fields
 
-## Notes
+## EDA
+- See `assets/feature_dists.png` and `assets/target_dist.png` for summary distributions.
+
+## Intended Use
+Educational use for practice with tabular data, augmentation, and Hugging Face Datasets.
+
+## Ethical Notes
+All data collected is from personal, non-sensitive objects (pens/pencils). No PII.
+
+## AI Usage
+Some augmentation code was assisted with GenAI, transparently documented in this notebook.
