+## Non-Quattor instillation
+
+You first need a VM to work on and an IRIS account.
+if you have set up the VM with Grafana properly then there should be a `grafana.ini` file in this path `/etc/grafana`.
+
+Now you need to open the `grafana.ini` config file and make note of the domain which should look like this:
+`domain=host-(`Hostname`).nubes.stfc.ac.uk`.
+
+You will need a self signed certificate and key to put in `/etc/grid-security/hostcert.pem` and `/etc/grid-security/hostkey.pem` respectively.
+
+Check the configuration of the datasources and set the password in `secrets/apel_db_pwd`. The details for that would come from whoever manages the database your using.
+
+In IRIS Create a new client and give it a name,
+for the Redirect URLs you will need the domain from the config file and it will look like this:
+- `https://(`domain`):(`port`)/login/generic_oauth`
+- `http://(`domain`):(`port`)/login/generic_oauth`
+
+After that you will need to put the Client id you get from the client and put it in `/etc/grafana/secrets/iris_iam_client_id`.
+You will also need to put Client secret from the Credentials section of client config into `/etc/grafana/secrets/iris_iam_client_secret`.
