+Ever wanted all of your most useful cryptographic operations in one module and not had to surf documentation for various packages? 
 CAS is here to provide a unified development experience as an abstract layer to the RustCrypto and Dalek-Cryptography suite of algorithms.
 The official NPM page can be found [here](https://www.npmjs.com/package/cas-typescript-sdk).

 **Note: All work is experimental and we understand some benchmarks might not be the most optimal.**
 
-This Node.js NPM module is dependent on our Rust layer [here](./src) that contains methods to run industry standard cryptographic operations sequentially, on threads, and the thread pool.

 ## Consuming Library Documentation
+This Node.js NPM module is dependent on our Rust layer [here](./src) that contains methods to run industry-standard cryptographic operations sequentially, on threads, and the thread pool.

 We utilize some smart people's existing work and we believe their documentation should be reviewed when possible.

 ## Disclaimer
 Many of the cryptographic crates that are utilized in our core FFI [layer](./src) have never had a security audit performed. Utilize this SDK at your own risk.
