+One approach consists in using a Markdown preprocessor such as
+[mdoc](https://github.com/scalameta/mdoc). These tools read your Markdown source files, search for code fences,
 evaluate them (throwing an error if they don’t compile), and produce a copy of your Markdown files where
 code fences have been updated to also include the result of evaluating the Scala expressions.
 
-For instance, given the following `src/documentation/getting-started.md` file:
-
-{% highlight markdown %}
-# Getting Started
-
-First, start with the following import:
-
-```scala
-import ch.epfl.scala.Example
-```
-
-Then, do nothing with something:
-
-```scala
-Example.doNothing(42)
-```
-{% endhighlight %}

-The tut tool will produce the following Markdown file:
-
-{% highlight markdown %}
-# Getting Started
-
-First, start with the following import:
-
-```scala
-scala> import ch.epfl.scala.Example
-import ch.epfl.scala.Example
-```
-
-Then, do nothing with something:
-
-```scala
-scala> Example.doNothing(42)
-res0: Int = 42
-```
-{% endhighlight %}
-
-You can see that `tut` code fences have been replaced with `scala` code fences, and the result of
-evaluating their content is shown, as it would look like from a REPL.
-
-To enable tut, add the following line to your `project/plugins.sbt` file:
-
-~~~ scala
-addSbtPlugin("org.tpolecat" % "tut-plugin" % "0.6.10")
-~~~
-
-And apply the following changes to your `build.sbt` file:
-
-{% highlight diff %}
-+enablePlugins(TutPlugin)
--Paradox / sourceDirectory := sourceDirectory.value / "documentation"
-+tutSourceDirectory := sourceDirectory.value / "documentation"
-+Paradox / sourceDirectory := tutTargetDirectory.value
-+makeSite := makeSite.dependsOn(tut).value
-{% endhighlight %}
-
-These changes add the `TutPlugin`, configure it to read sources from the `src/documentation` directory,
-configure Paradox to read the output of tut, and make sure tut is run before the site is built.
