+## Command line version of mkString
+
+In this example, [fs2] is used to read a stream of newline delimited strings from standard input and to reconcatenate them with comma by default, while [decline] is leveraged to parse the command line options.

+Compiling this example with [scala-native], adding these directives
+
+```scala mdoc:reset:silent
+//> using packaging.output "mkString"
+//> using platform "native"
+//> using nativeMode "release-fast"

+
+will produce a native executable that can be used in a similar way as the Scala's standard library `.mkString`:

+# typelevel-toolkit
+
+A toolkit of **great libraries** to start building **Typelevel** apps on JVM, Node.js, and Native!
+
+Our very own flavour of the [Scala Toolkit].
+
+## Overview
+
+Typelevel toolkit is a meta library that currently includes these libraries:
+
+- [Cats] and [Cats Effect]
+- [fs2] and [fs2 I/O]
+- [fs2 data csv] and its generic module
+- [Http4s Ember client]
+- [Circe] and http4s integration
+- [Decline Effect]
+- [Munit Cats Effect]
+
+and it's published for Scala 2.12, 2.13 and 3.2.2.
+
+To use it with [Scala CLI] use this directive:
+```scala
+//> using lib "org.typelevel::toolkit::@VERSION@"
+```
+
+Albeit being created to be used with [Scala CLI], typelevel-toolkit can be imported into your `build.sbt` using:
+```scala
+libraryDependencies += "org.typelevel" %% "toolkit" % "@VERSION@"
+// for native and js
+libraryDependencies += "org.typelevel" %%% "toolkit" % "@VERSION@"
+```
+
+## Quick Start Example
+@:select(scala-version)
+@:choice(scala-3)

+//> using lib "org.typelevel::toolkit::@VERSION@"
+
+import cats.effect.*

+  def run = IO.println("Hello toolkit!")
+```
+@:choice(scala-2)
