Within the Kiln file view, you can easily see information about where each line in the file came from, which user modified it last, and which commit it’s from. Here’s how:

  1. In your repository, under the Files tab, find the file you wish to annotate and click on the file name.
  2. From here, there is an Annotate button on the top-right of the screen. Clicking this will annotate the file you’re currently browsing.

You can also use the TortoiseHg application to do this from your local machine. While currently browsing your working directory in a command prompt, type hgtk annotate <file path goes here> and it will do a much more detailed annotation.
