+# Catalog description
+
+This catalog exists as an margin cache of the small_sky_order1 table,
+allowing spatial operations to be performed efficiently and accurately.
+
+This catalog was generated using the following snippet:
+
+```
+from hipscat_import.margin_cache.margin_cache_arguments import MarginCacheArguments
+from hipscat_import.margin_cache import generate_margin_cache
+
+margin_args = MarginCacheArguments(
+    margin_threshold=7200,
+    input_catalog_path="data/small_sky_order1",
+    output_path="data/",
+    output_artifact_name="small_sky_order1_margin"
+)
+
+
+if __name__ == "__main__":
+    generate_margin_cache(margin_args, client)
+```
+
+NB: 
+
+- The setting `margin_threshold` at 7200 arcseconds (2 degrees) is much higher than
+  a usual margin cache would be generated at, but is used because the small sky test
+  dataset is sparse.
