 # `rust_json_schema`
 
+[![Gem Version](https://badge.fury.io/rb/rust_json_schema.svg)](https://rubygems.org/gems/rust_json_schema)
+
 `rust_json_schema` is a Ruby wrapper gem for Rust's [jsonschema-rs crate](https://github.com/Stranger6667/jsonschema-rs).
 
+This gem ships with precompiled binaries for Linux and macOS. Check the available gems on [Rubygems](https://rubygems.org/gems/rust_json_schema).

 ## Warning
 
 I do not have any significant Rust programming experience, but this gem satisifies a need for a performant JSON Schema validation tool in Ruby land. While I intend to use this gem in a production environment, consider this code and library entirely experimental, at least until a 1.0 release, if it ever comes to that.
 
 [rusty_json_schema](https://github.com/driv3r/rusty_json_schema) is a direct source of inspiration (and in some cases, literal copy and paste, like some fixtures/specs). Now that [bundler has explicit support for rust-backed Ruby gems](https://bundler.io/blog/2023/01/31/rust-gem-skeleton.html) as of early 2023, the Rust library code is a lot simpler that it previously needed to be, largely thanks to [magnus crate](https://github.com/matsadler/magnus) and the [rb-sys gem](https://github.com/oxidize-rb/rb-sys/tree/main/gem).
 
-Eventually I intend to ship common platform binaries as part of this gem, eliminating the need for a Rust toolchain on client machines, but that is not yet the case.
