"Only the IST sends BPDUs for the MST region; all M-records are encapsulated in that one BPDU that the IST sends.? is shown twice.
Either remove the text (same as N3K and N5K)
Or move the above text as part of the description of Figure 9

2. Under Enabling MST ? CLI Version
The following commands are missing in step 2 of summary steps:
spanning-tree mode mst
no spanning-tree mode mst

3. Under Entering MST Configuration Mode
The following commands are missing in step 2 of summary steps:
spanning-tree mode mst configuration
no spanning-tree mode mst configuration

The following commands are missing in step 3 of summary steps:
exit
abort

Change the example To
switch# config t
switch(config)# spanning-tree mst configuration 
switch(config-mst)#exit
switch(config)#

4. Under Specifying the MST Name
The following commands are missing in step 4 of summary steps:
exit
abort

Change the example to
switch# config t
switch(config)# spanning-tree mst configuration

switch(config)#

5. Under Specifying the MST Configuration Revision Number
The following commands are missing in step 4 of summary steps:
exit
abort

Change the example to

switch(config-mst)# exit
switch(config)#

6. Under Specifying the Configuration on an MST Region
The following commands are missing in step 6 of summary steps:
exit
abort

Change the example to

switch(config-mst)# instance 1 vlan 10-20
switch(config-mst)# name region1

7. Under Mapping or Unmapping a VLAN to an MST Instance - CLI version
The following commands are missing in step 3 of summary steps:
instance instance-id vlan vlan-range
No instance instance-id vlan vlan-range

The following commands are missing in step 4 of summary steps:
exit
abort

Add exit at the end of the example. I.e. 
switch# config t
switch(config)# spanning-tree mst configuration
switch(config-mst)# instance 3 vlan 200
switch(config-mst)#exit
switch(config)#

8. Under Mapping Secondary VLANs to Same MSTI as Primary VLANs for Private VLANs
The following commands are missing in step 4 of summary steps:
exit
abort

Add exit at the end of the example. I.e.
switch# config t
switch(conf9g)# spanning-tree mst configuration
switch(config-mst)# private-vlan synchronize
switch(config-mst)# exit
switch(config)#

9. Under Configuring the Root Bridge
The following commands are missing in step 2 of summary steps:
spanning-tree mst instance-id root {primary | secondary} [diameter dia [hello-time hello-time]]
no spanning-tree mst instance-id root

The following commands are missing in step 3 of summary steps:
