I want to give short feedback.
On old website there was example of UI and pipeline. Now there is no example and it is very bad.
I suggest to add example of pipeline in concourse like before. It is important to let people touch tool in easy way. Or short video on youtube. Whatever, but let people touch the tool as fast as possible. Now there is tons of docs, while people don’t even know if they are interested in. Let them feel comfortable about investing they time to read this doc. They should know it is worth it first.
