+Operator users typically will just need to install the *pgo* client
+in order to work with an already deployed Postgres Operator.
+
+For installing the Operator on the Kubernetes server, see
+the [Installation Guide](https://crunchydata.github.io/postgres-operator/stable/installation/).
+
+### pgo Client Installation
+
+The *pgo* binary is pre-compiled and available to download from the projects
+github repository [Releases](https://github.com/crunchydata/postgres-operator)  page.
+
+Add the *pgo* binary to your PATH and make it executable.
+
+Next, create a *.pgouser* file in your $HOME directory or 
+set the PGOUSER environment variable to point to a *.pgouser*
+file location:
+
+    export PGOUSER=/somepath/.pgouser
+
+Alternatively, if you create a *.pgouser* file in your $HOME, the *pgo*
+client will find the file there.
+
+Set the name of the Kubernetes namespace that you want to 
+access, on a Linux host you would enter:
+
+    export PGO_NAMESPACE=pgouser1
+
+Set the URL of the Operator REST API, in this example the Operator is running 
+on a host with IP address 192.168.0.120, see your administrator for
+the correct IP address, on a Linux host you would enter:
+
+    export PGO_APISERVER_URL=https://192.168.0.120:8443
+
+Next, add the TLS keys required for the *pgo* client to connect to the
+Operator REST API, see your administrator for access to these keys, on a Linux host you would enter:
+
+    export PGO_CA_CERT=/somepath/someserver.crt
+    export PGO_CLIENT_CERT=/somepath/someserver.crt
+    export PGO_CLIENT_KEY=/somepath/someserver.key
+
+Lastly, test out the connection:
+
+    pgo version
