 ## TL;DR
 
-This dataset packages one official `XLSX` resource from **Chad** as
-ML-ready Parquet. The source file is the provenance boundary; all usable
-indicators or tabular columns from the resource stay together in this repo.
+This dataset contains **332 rows** from **Insecurity Insight**, covering **Explosive Weapons Monitor Data by Insecurity Insight**. It is published as ML-ready Parquet with consistent Hugging Face metadata, source provenance, and analysis-friendly loading examples.

+## Data Quality Notes
+
+- No canonical year/date column was detected in the packaged table; use source metadata and domain context for temporal interpretation.
+- Missing values are preserved rather than silently imputed.
+- Column names are standardized for machine use; source meanings are preserved where known.
+- Always confirm source methodology, units, and collection definitions before policy, production, or redistribution-sensitive use.

+## Suggested Analyses
+
+- Profile the distribution of values
+- Compare categories or geographies
+- Join with complementary public datasets
+- Check missingness before modeling
+- Use `country_iso3` as the safest geography join key when present
