I'd like to see a little more context around this link, but we should probably also backport it, maybe to all supported versions. @camunda/tech-writers can one of you assist Falko with both of those things? 🙂

[mesellings]

@falko I'll take a look and backport as well for you 👍

The same FEEL Scala docs section also contains examples for other topics. Maybe we should just add them to the docs? @saig0 FYI

[saig0]

@falko instead of adding a link to the FEEL-Scala docs, I would prefer adding the examples directly in the C8 docs. On a long-term, I would move all relevant content to the Camunda docs (and the code itself to the Camunda repo).

[mesellings]

@saig0 @falko I think moving content into the docs may be quite a lift for this PR, and probably something we need to plan out - there are issues such as redirects/links to the github docs for example that we need to take into consideration.

Can I suggest the following plan:

For now (for this PR) we add the links in as suggested, and we can reference the examples a bit more clearly. For example:

Info: Temporal expression examples are available in the FEEL-Scala documentation, including how to compare and check dates, calculate age and duration, and change date format.

Then, we address moving relevant docs over (such as these examples) as part of a larger project?

[falko]

@akeller can we just merge all examples from here: https://github.com/camunda/feel-scala/tree/main/docs/docs/learn/samples

Really helpfule, would be to somehow integrate the FEEL playground into the docs so that users can directly modify the examples to match their use cases. It could be done as a link near each example or even directly like how @saig0 did it in his FEEL Challenge. Having the examples in the playground could also be a way to maintain them, i.e. test that they still work.
