+## Web REPL
+
+Web REPL you can access from [Home page](/) or as a [bookmarklet](/#bookmark) use
+[jQuery Terminal](https://terminal.jcubic.pl/) and supports those features:
+* syntax highlighting using [Prism.js](https://prismjs.com/),
+* parentheses matching - when you type close parenthesis it will jump for a split second into it's
+  matching open parenthesis,
+* auto indentation - when you press enter it auto indent and if you copy paste the code it will reformat it.
+* doc string tooltip - when you hover over a symbol it will show the docstring in a tooltip
+
+## Node.js REPL
+
+Node.js version of the REPL, also supports syntax hightlighting and auto indentation. It also
+supports [paste bracket mode from Node.js](https://github.com/nodejs/node/pull/47150) (added by
+[Jakub T. Jankiewicz](https://jcubic.pl/me) and released in
+[v20.6.0](https://nodejs.org/en/blog/release/v20.6.0)), to properly handle copy-paste of Scheme
+code.
+
+In the future the Node.js REPL may also support parentheses matching. It's supported by
+[CLisp](https://www.gnu.org/software/clisp/) and [Common Lisp](https://common-lisp.net/)
+interpreter.
