You do not need a quarter-long project to get a doc-grounded support agent live. Most teams connect their first sources and see real answers the same afternoon. Here is a practical order to work through.
Start with what you already have
Point Serochat at the content that answers the most questions today: your help centre articles, product docs, and a handful of key web pages. You can also upload PDFs and add short question-and-answer pairs to cover the gaps your docs do not.
Keep answers accurate as content changes
Your documentation moves, so re-sync a source whenever it does. Because every answer links to the source it used, it is easy to spot a reply leaning on something out of date and fix it at the root rather than papering over it in the bot.
Let real questions guide you
Once visitors start chatting, read the conversations. The questions people actually ask are the fastest guide to which article to write next or which answer to tighten. A support agent is never really finished, and that is the point: it improves as your content does.
