 ## UDF Examples
+
 We have two different types of UDFs in Couchbase, using Javascript for the Query service and using Python for the Analytics service. Here, we showcase the same UDF functionality of calculating the distance between two GPS coordinates for the two services.

 ### Query Service UDF using Javascript
 
-Couchbase allows you to create User Defined Functions (UDF) with Javascript to include custom business logic inside your SQL++ queries while querying the data stored in Couchbase.  Here, we create a custom UDF that calculates the distance between two GPS coordinates using the [Haversine formula](https://en.wikipedia.org/wiki/Haversine_formula).

 ### UDF Code
+
 - The UDF code is [here](analytics-udf-python/distance-lib/distance_library.py).
 
 #### Testing the UDF
 
 - Run the test [code](analytics-udf-python/distance-lib/test_distance_library.py).
-

   `$ python test_distance_library.py`
 
 #### Importing the UDF into Couchbase
 
 - The Python module can be packaged including all the dependencies using shiv for any platform. We use Linux here for our container.
 
-  > $ shiv -o distance-lib.pyz --site-packages . --platform manylinux2010_x86_64 --python-version 39 --only-binary=:all: geopy
+  ```bash
+  $ cd distance-lib
