Reviewed — this is a small, low-risk documentation-only change (README.md, +13/-4). Overall it reads well and the cleanup (removing the now-resolved homebrew-chicks#74 "coming soon" bullet) is a nice touch.

A few notes:

Accuracy to double-check

• The line "on other platforms it falls back to building from source with go" is a specific behavioral claim about the chicks-net/chicks tap formula. Worth confirming the formula actually has an on_macos/on_linux/source-build fallback stanza for unsupported platforms (e.g. non-amd64/arm64 Linux) before merging, so the README doesn't overpromise. If the formula is bottle-only with no source fallback, this line should be adjusted.
• Tap coordinates chicks-net/chicks/ctm imply a chicks-net/homebrew-chicks tap repo with an ctm formula — this matches the repo referenced in the removed issue link, so naming looks consistent, but it's worth a quick brew install chicks-net/chicks/ctm smoke test on a real machine (or CI) if that hasn't already been done, since a broken install command in the README is worse than no install command.

Minor

• "I'd like to get this into Debian eventually too" reads a bit oddly right after the Homebrew instructions — might flow better as its own short paragraph or folded into a "Coming soon" bullet in the Status section for consistency with how the Homebrew item was tracked before, but this is a style nit, not a blocker.

Testing/CI

• No code changes, so no test coverage concerns — just test/just fmt shouldn't be affected. Might be worth running just markdown lint (markdownlint-cli2) locally if not already covered by CI, just to catch any formatting nits in the new code fences.

No security or performance concerns — this is documentation-only. Nice, focused change overall.
