-Compute instances are replacing the Notebook VM.  In regions where compute instances are not available yet, you can continue to use Notebook VMs with full functionality and create new Notebook VMs.
+Compute instances are replacing the Notebook VM.  
 
 Any notebook files stored in the workspace file share and data in workspace data stores will be accessible from a compute instance. However, any custom packages previously installed on a Notebook VM will need to be re-installed on the compute instance. Quota limitations which apply to compute clusters creation will apply to compute instance creation as well. 
 
-In regions where compute instances are available, new Notebook VMs cannot be created. However, you can still access and use Notebook VMs you have created, with full functionality. Compute instances can be created in same workspace as the existing Notebook VMs.
