 1. To export the data from the source MongoDB instance, open a terminal on the MongoDB instance machine. If it is a Linux machine, type
 
-    `mongoexport --host HOST:PORT --authenticationDatabase admin -u USERNAME -p PASSWORD --db edx --collection query --out edx.json`
+    ```bash
+    mongoexport --host HOST:PORT --authenticationDatabase admin -u USERNAME -p PASSWORD --db edx --collection query --out edx.json
+    ```
 
     On windows, the executable will be `mongoexport.exe`. *HOST*, *PORT*, *USERNAME*, and *PASSWORD* should be filled in based on the properties of your existing MongoDB database instance. 
 
     You may also choose to export only a subset of the MongoDB dataset. One way to do this is by adding an additional filter argument:
 
-    `mongoexport --host HOST:PORT --authenticationDatabase admin -u USERNAME -p PASSWORD --db edx --collection query --out edx.json --query '{"field1":"value1"}'`
+    ```bash
+    mongoexport --host HOST:PORT --authenticationDatabase admin -u USERNAME -p PASSWORD --db edx --collection query --out edx.json --query '{"field1":"value1"}'
+    ```
 
     Only documents which match the filter `{"field1":"value1"}` will be exported.

 1. To create a BSON data dump of your MongoDB instance, open a terminal on the MongoDB instance machine. If it is a Linux machine, type
 
-    `mongodump --host HOST:PORT --authenticationDatabase admin -u USERNAME -p PASSWORD --db edx --collection query --out edx-dump`

     *HOST*, *PORT*, *USERNAME*, and *PASSWORD* should be filled in based on the properties of your existing MongoDB database instance. You should see that an `edx-dump` directory is produced and that the directory structure of `edx-dump` reproduces the resource hierarchy (database and collection structure) of your source MongoDB instance. Each collection is represented by a BSON file:
