 Chocula is a python script to parse and merge journal-level metadata from
 various sources into a consistent sqlite3 database file for analysis.
 
-See `chocula_schema.sql` for the output schema.
+## Quickstart
+
+You need `python3`, `pipenv`, and `sqlite3` installed.
+
+First fetch datasets:
+
+    cd data
+    ./fetch.sh
+    cd ..
+
+Then re-generate entire sqlite3 database from scratch:
+
+    pipenv shell
+    ./chocula.py everything
+
+Now you can explore the database; see `chocula_schema.sql` for the output schema.
