 ## Key Features of Go+
 
 * Approaching natural language expression and intuitive (see [How Go+ simplifies Go's expressions](#how-go-simplifies-gos-expressions)).
+* Smallest but Turing-complete syntax set in best practices (see [Go+ Specification for STEM Education](doc/spec-mini.md)).
 * Fully compatible with [Go](https://github.com/golang/go) and can mix Go/Go+ code in the same package (see [Go/Go+ Hybrid Programming](doc/docs.md#gogo-hybrid-programming)).
 * Integrating with the C ecosystem including Python and providing limitless possibilities based on [LLGo](https://github.com/goplus/llgo) (see [Support for C/C++ and Python](#support-for-cc-and-python)).
 * Does not support DSL (Domain-Specific Languages), but supports SDF (Specific Domain Friendliness) (see [Go+ Classfiles](#go-classfiles)).
