+
+Official Homebrew tap for OWASP CRS tools.
+
+This tap provides Homebrew cask formulae for [crs-toolchain](https://github.com/coreruleset/crs-toolchain) and other OWASP CRS utilities. Cask formulae are automatically updated via [GoReleaser](https://goreleaser.com/) on each release of `crs-toolchain` or other tools in the OWASP CRS organisation.
+
+## Installation
+
+Add this tap to Homebrew:
+
+```sh
+brew tap coreruleset/tap
+```
+
+Then install a tool, for example `crs-toolchain`:
+
+```sh
+brew install --cask crs-toolchain
+```
+
+## Upgrade
+
+```sh
+brew upgrade --cask crs-toolchain
+```
+
+## Uninstall
+
+```sh
+brew uninstall --cask crs-toolchain
+```
+
+To also remove the tap:
+
+```sh
+brew untap coreruleset/tap
+```
