+= Customizing the login page
+
+Create Terms of Service information with custom login pages. Custom login pages
+can also be helpful if you use a third-party login provider, such as GitHub or
+Google, to show users a branded page that they trust and expect before being
+redirected to the authentication provider. You can also render custom error
+pages during the authentication process.
+
+.Prerequisites
+
+* You must have administrator privileges.
+
+.Procedure
+

++
+----
+$ oc adm create-login-template > login.html
+$ oc adm create-provider-selection-template > providers.html
+$ oc adm create-error-template > errors.html
+----
+
+. Create the secrets:
++
+----
+$ oc create secret generic login-template --from-file=login.html -n openshift-config
+$ oc create secret generic providers-template --from-file=providers.html -n openshift-config
+$ oc create secret generic error-template --from-file=errors.html -n openshift-config
+----
+
+. Run:
++
+----
+$ oc edit oauths cluster
+----
+
+. Update the specification:
++
+----
+spec:
+  templates:
+    error:
+        name: error-template
+    login:
+        name: login-template
+    providerSelection:
+        name: providers-template
+----
