File	Description

[Copilot]

In this note, the command name should be formatted as code (for consistency with the rest of the article, e.g., dsreg earlier) and the blockquote content should not have the extra leading space after > (use > Once ...).

Suggested change

	> Once you install the `microsoft-identity-broker`, the dsreg tool is available system-wide.
