+Scrapes strain info, stores for later reference.
+
+Clone repo and run the command. Resulting data can be found in `db.json`.
+
+```
+yarn install
+yarn start
+```
+
+**NOTE**: You may need to run it multiple times (4 or 5 should do it), since some strains will get skipped the first few times. I don't know if it's leafly's endpoint or some weird race condition in the scraping code though.
