+# Caveats
+
+* Extracting branches and hashtags is a really expensive operation. At the
+moment the plugin works for "small" repositories (~50K commits). With bigger
+repositories the plugin might cause OOM.
+
+* It is not possible to extract data about a single commit, but only aggregations
+of them.
