Duplicates #1250

[anxinyf]

That will be great to generate doc, like swagger or other tools.

[bobcatfish]

Note I think this is a duplicate of #1250

[anxinyf]

Yes! I didn't know this issue #1250 before. But These api docs(Pipeline/Dashboard/Triggers) are wrriten manually, maybe some tools are better, like swagger.

[anneqm]

Per @anxinyf this item can be closed.

Where is the non-go API documentation available? I'd like to validate my Tekton resources with kubeval. It isn't clear how this issue was resolved

[afrittoli]

It looks like #1250 and #2055 were both closed as duplicate of each other. I think one of the two should stay open? @sbwsg @bobcatfish

Sorry for the churn but I'm actually going to make #1250 the source of truth here. The description of that issue aligns more closely with what we want for the project I think - generated documentation from the existing API definition.
