+
+Now before you can run the bot you've got to setup Postgres. Head to [this page](https://www.enterprisedb.com/downloads/postgres-postgresql-downloads) and download the Windows x86-64 installer.  
+Don't change any of the defaults (unless you know what they mean) and make note of the password you've picked. You'll need it later.
