 **Note:** Currently, it's pre-0.1, and is likely to change a bit before it stabilizes enough for a crates.io release.
 
+Rhai's current feature set:
+
+* Straightforward integration with your application
+* Fairly efficient (1 mil iterations in 0.75 sec on my 5 year old laptop)
+* Low compile-time overhead (~4 secs for debug build, ~11 secs for release build)
+* Simple, easy-to-use scripting language
+* Support for overloaded functions
+* No additional dependencies
+* No unsafe code

 ## Functions
 
+Rhai supports defining functions in script:

+fn add(x, y) {

+
+Just like in Rust, you can also use an implicit return.
