-It's hot-swapping friendly when you use [calcit-editor](https://github.com/calcit-lang/editor). Install it and run `ct` to launch editor server, which writes `compact.cirru` and `.compact-inc.cirru` on saving. Try launching example by cloning [Calcit Workflow](https://github.com/calcit-lang/calcit-workflow).

 ## Features
 
 * Immutable Data
 
-Values and states are represented in different data structures, which is the semantics from functional programming. Internally it's [im](https://crates.io/crates/im) in Rust and a custom [finger tree](https://github.com/calcit-lang/ternary-tree.ts) in JavaScript.
+Values and states are represented in different data structures, which is the semantics from functional programming. Internally it's [rpds](https://docs.rs/rpds/) in Rust and a custom [2-3 tree](https://github.com/calcit-lang/ternary-tree.ts) in JavaScript.
 
 * Lisp(Code is Data)
 
 Calcit-js was designed based on experiences from ClojureScript, with a bunch of builtin macros. It offers similar experiences to ClojureScript. So Calcit offers much power via macros, while keeping its core simple.
 
-* Indentations
+* Indentations-based Syntax
 
 With `bundle_calcit` command, Calcit code can be written as an indentation-based language. So you don't have to match parentheses like in Clojure. It also means now you need to handle indentations very carefully.
