Four characters that just changed how I build Claude project templates: <!--

When you upload templates or other files (e.g. a DNA profile) to a project's knowledge base, you can keep your own notes and hints directly inside the document – without them being treated as content. Just use HTML comments:

This works in Markdown files (.md) just as it does in HTML. Claude recognizes them as comments and doesn't include them as content in its responses, so you don't have to delete your explanations before uploading.

Example from a DNA-profile markdown file:

## How I Communicate

### My writing style

[TEXT]

Hope this is useful to some of you.

Best regards from Berlin
