 ## Initial configuration for OSM deployment
 
-if you have an initial configuration that needs to be applied in the NSD deployment, then you go to the RFS (or CFS) and in Service Specification Characteristics go and edit the OSM_CONFIG characteristic. 
+if you have an initial configuration that needs to be applied in the NSD deployment, then you go to the RFS (or CFS) and in Service Specification Characteristics go and edit the OSM_CONFIG characteristic.
 You can add in the Service Characteristic Value, in the Value field something like the following example which gives a floating IP to a VNF:
 
-```
+```json
 { "nsdId": "e855be91-567b-45cf-9f86-18653e7ea", "vimAccountId": "4efd8bf4-5292-4634-87b7-7b3d49108" , "vnf": [ {"member-vnf-index": "1", "vdu": [ {"id": "MyCharmedVNF-VM", "interface": [{"name": "eth0", "floating-ip-required": true }]}]}]}
- 
 ```
 
 or a more complex example (beautify it first if you want to view it, but in the parameter OSM_CONFIG must be minified like the example):
 
-```
+```json
