 title: Copy the replica set configuration to a variable.
 stepnum: 1
 ref: copy-configration-object
+pre: |
+  In the :program:`mongo` shell, use :method:`rs.conf()` to retrieve
+  the replica set configuration and assign it to a variable. For
+  example:
 action:
-  - pre: |
-      In the :program:`mongo` shell,
-      use :method:`rs.conf()` to retrieve the replica set configuration and
-      assign it to a variable. For example:
-    language: javascript
-    code: |
-      cfg = rs.conf()
+  language: javascript
+  code: |
+    cfg = rs.conf()

 title: Change each member's priority value.
 stepnum: 2
 ref: change-priority-values
+pre: |
+  Change each member's :data:`~local.system.replset.members[n].priority` 
+  value, as configured in the :data:`~local.system.replset.members`
+  array.
 action:
-  - pre: |
-      Change each
-      member's :data:`~local.system.replset.members[n].priority` value, as
-      configured in the :data:`~local.system.replset.members`
-      array.
+  language: javascript
+  code: |
+    cfg.members[0].priority = 0.5
+    cfg.members[1].priority = 2
+    cfg.members[2].priority = 2
 post: |
-  The following example uses the ``cfg`` variable to change the
-  priority for the first three members configured in the array.
-language: javascript
-code: |
-  cfg.members[0].priority = 0.5
-  cfg.members[1].priority = 2
-  cfg.members[2].priority = 2
+  This sequence of operations modifies the value of ``cfg`` to set the
+  priority for the first three members defined in the
+  :data:`~local.system.replset.members` array.

 title: Assign the replica set the new configuration.
 stepnum: 3
 ref: assign-new-config
+pre: |
+  Use :method:`rs.reconfig()` to apply the new configuration.
 action:
-  - pre: |
-      Use :method:`rs.reconfig()` to apply the new configuration.
+  language: javascript
+  code: |
+    rs.reconfig(cfg)
 post: |
-  For example, to assign the replica set the new
-  configuration in from the ``cfg`` variable, issue the following:
-language: javascript
-code: |
-  rs.reconfig(cfg)
+  This operation updates the configuration of the replica set using
+  the configuration defined by the value of ``cfg``.
