Recorder fingering charts

Hello everyone,

I am looking to make recorder fingering charts using Lilypond. Current =
documentation does not list recorder as available for woodwind fingering =
diagrams:
=20
=
https://lilypond.org/doc/v2.24/Documentation/notation/woodwind-diagrams.ht=
ml=20

However, I checked the github repository and there are files mentioning =
a recorder fingering chart :

=
https://gitlab.com/lilypond/lilypond/-/blob/master/Documentation/snippets/=
recorder-fingering-chart.ly=20

Have the changes not been added to the latest stable version yet?

On top of the baroque recorder fingering chart (thumb hole, 7 finger =
holes including 2 double holes, bell hole), I would like to add charts =
for keyed recorders. Not only the well established keyed tenor recorders =
(thumb hole, 6 finger holes including 1 double hole, C# and C keys, bell =
hole).=20
I would also like to make diagrams that fit keyed recorders, such as the =
Helder instruments by Mollenhauer. I attached in this email a screenshot =
of a baroque recorder fingerging chart, and that of the Helder =
instruments.

I would also like to be able to make my own diagrams. Notably for the =
Helder alto with extra C# and D# keys. To my knowledge, Mollenhauer has =
never published a fingering chart for this instrument. And who knows =
what recorder models will be developed in 10, 20 or 50 years?
A community-based fingering database for keyed recorders would be a huge =
contribution to the recorder world. Using neat diagrams with Lilypond =
would significantly improve the experience.

Can the Lilypond community help me with that? I have a degree in NLP so =
I can code=E2=80=A6 to some extent!

I look forward to hearing from you.
