How do you get a pipe added to the pipe integrations page

Question

How does one go about getting a pipe added to the integrations page (there are 65 at the time of writing)

https://bitbucket.org/product/features/pipelines/integrations

Although I found the way to get them added:

https://bitbucket.org/bitbucketpipelines/official-pipes/src/master/README.md

When I try to follow the guide and run the script as it suggests:

python build.py 'pipes/my-pipe-name.yml'

I receive the following error:

File "build.py", line 145
REPOSITORY_TAGS_URL = f"https://api.bitbucket.org/2.0/repositories/{repository_path}/refs/tags?sort=-name&pagelen=100"
^
SyntaxError: invalid syntax

Thanks

Posting the resolution in case it helps anyone else:

The issue with the python script was that I was running it using Python2 (2.7) and the string formatting using "f"https:// ..." as a format wasn't supported til Python 3.

Running on python 3.6, and after installing modules like yaml, docker, cerberus, colorlog, joblib etc finally got it running.
