-# shellcheck-m1
+# ShellCheck binaries for the VS Code extension
 
-Sync homebrew'ed Apple M1 shellcheck build.
+ShellCheck binaries distributed in `.tar.gz` format for Linux and macOS, including M1 Macs. Used by [ShellCheck VS Code extension](https://github.com/vscode-shellcheck/vscode-shellcheck).
+
+## Why?
+
+- ShellCheck doesn't officially provide binaries for M1 Macs.
+- ShellCheck ships binaries packaged in `.tar.xz` format, in which [`bindl`](https://github.com/felipecrs/bindl/issues/217) doesn't support.
+
+## How to generate more binaries?
+
+Simply push a new tag to this repository in the format `v*.*.*` matching the [ShellCheck version](https://github.com/koalaman/shellcheck/releases). The CI will generate binaries for all supported platforms and upload them to the release.
