+[[brew]]
+=== Install {kib} on macOS with Homebrew
+
+Elastic publishes Homebrew formulae so you can install {kib} with the https://brew.sh/[Homebrew] package manager.
+
+To install with Homebrew, you first need to tap the Elastic Homebrew repository:
+
+[source,sh]
+-------------------------
+brew tap elastic/tap
+-------------------------
+
+Once you've tapped the Elastic Homebrew repo, you can use `brew install` to
+install the default distribution of {kib}:
+
+[source,sh]
+-------------------------
+brew install elastic/tap/kibana-full
+-------------------------
+
+This installs the most recently released default distribution of {kib}. To install the OSS distribution,
+specify `elastic/tap/kibana-oss`.
+
+[[brew-layout]]
+==== Directory layout for Homebrew installs

+When you install {kib} with `brew install`, the config files, logs,
