-This is a snippet that demonstrates how you can generate better looking citations in Copilot Studio.
+This snippet demonstrates how you can generate better looking citations in Copilot Studio for [uploaded documents](https://learn.microsoft.com/microsoft-copilot-studio/nlu-documents).
+
+This allows to both display a **title** for the document, but also to point to a **URL** when the citation link is clicked, for example to download or open the document.
+
+> [!IMPORTANT]
+> **This assumes that you're responsibe for storing the files in a location where they are accessible to your users, when clicked.**
+
+The sample works both for uploaded files and other knowledge sources (e.g. public website, SharePoint / OneDrive).
+
+With this sample, you have two options, that can be used indepently from each other:
+1. Set a URL pointing to a folder where files are expected to be available to your users, when no URLs are available. For this, set the URL for your base folder in `Topic.UploadedFilesRootUrl`.
+1. Set a mapping between each document and a URL location for the file. For this, udpdated the `Topic.FilesSources` table. Make sure that each file name is encoded in the same way as returned as citation when an answer is generated (e.g. use %20 instead of spaces, etc.)
