Poem

🐰 I hopped through links with nimble feet,
Swapped old paths for guides more neat,
Broadened a URL with a twirl,
Placed a newline — a tiny pearl,
Docs refreshed, I give a cheer,
Little changes, wag the ear.

182-182: Use more descriptive link text for the wallet documentation.

The link text "this documentation" is vague and does not help users understand the destination before clicking. Per the coding guidelines: "Use descriptive link text."

Suggested improvement

-        See [this documentation](https://learn.mattr.global/docs/holding/go-hold/getting-started) for details.
+        See the [GO Hold getting started guide](https://learn.mattr.global/docs/holding/go-hold/getting-started) for download and setup instructions.
