 ## Quickstart
+
 ```bash
 make install

+### Environmental Variables
+
+All the variables listed below need to be set in your environment. The `kfutil` command will look for these variables
+and use them if they are set. If they are not set, the utility will fail to connect to Keyfactor.
+
+```bash
+export KEYFACTOR_HOSTNAME=<mykeyfactorhost.mydomain.com>
+export KEYFACTOR_USERNAME=<myusername> # Do not include domain
+export KEYFACTOR_PASSWORD=<mypassword>
+export KEYFACTOR_DOMAIN=<mykeyfactordomain>
+```
