+# Diesel setup
+
+These were the tasks I needed to perform before I could get diesel_cli
+installed.
+
+## Ubunutu
+
+These are the packages referenced in the README that need to be installed for
+postgresql and sqlite 3:
+
+* `postgresql`
+* `postgresql-contrib`
+* `libpq-dev` (Not enough to just set up postgresql, need this for `libpq`)
+* `sqlite3`
+
+Then needed to set up postgresql using
+[this](https://help.ubuntu.com/community/PostgreSQL) tutorial.
+
+After this was able to install diesel_cli and then run the setup with the newly
+created credentials following the instructions in [README](README.md)
