 # Optimal
 
+> **⚠️ This project is unmaintained.**  
+> **We recommend [NimbleOptions](https://github.com/dashbitco/nimble_options) instead.**

 Optimal is a schema based `opt` validator. It is verbose, but I've tried many other data validation libraries, and their succinctness came with a cost when it came to features. There are still a lot of optimizations and improvements that can be made, so contributions are very welcome.
 
 This `opt` validator has a bit of a niche. It fits in just fine with validating any keyword list, but its especially useful for validating compile-time options, like ones provided to functions in a DSL.
