Hello, is it possible to add comments in YAML files ?

I tried with "#" but Builder is removing them each time I edit the file... Thanks

You are doing it right, I suppose the Builder plugin does not take care of preserving comments on updating the yaml file. You may submit a bug report if this is important to you, but I suspect it might not be trivial to persist comments.

Looks like a dead-end (The Symphony Yaml component is used by October Yaml parsing):

@Incremental the Builder does not retain comments as it rewrites the YAML file every time changes are made to them.

Thanks for your answers, the simplest is probably to keep a documentation with my developements ;-)
