 ## Install
 
-At the moment, the only way to install mdBook is by downloading the source code from Github and building it yourself. Fortunately
-this is made very easy with Cargo.
+### Pre-requisite
 
-If you haven't already, you should begin by installing [Rust](https://www.rust-lang.org/install.html) and [Git](https://git-scm.com/downloads)
+mdBook is written in **[Rust](https://www.rust-lang.org/)** and therefore needs to be compiled with **Cargo**, because we don't yet offer ready-to-go binaries. If you haven't already installed Rust, please go ahead and [install it](https://www.rust-lang.org/downloads.html) now.
 
-Open your terminal and navigate to the directory of you choice. We need to clone the git repository and then build it with Cargo.
+### Install Crates.io version
+
+Installing mdBook is relatively easy if you already have Rust and Cargo installed. You just have to type this snippet in your terminal:
+
+```bash
+cargo install mdbook
+```
+
+This will fetch the source code from [Crates.io](https://crates.io/) and compile it. You will have to add Cargo's `bin` directory to your `PATH`.
+
+Run `mdbook help` in your terminal to verify if it works. Congratulations, you have installed mdBook!
+
+
+### Install Git version
+
+The **[git version](https://github.com/azerupi/mdBook)** contains all the latest bug-fixes and features, that will be released in the next version on **Crates.io**, if you can't wait until the next release. You can build the git version yourself. Open your terminal and navigate to the directory of you choice. We need to clone the git repository and then build it with Cargo.
 
 ```bash
 git clone --depth=1 https://github.com/azerupi/mdBook.git

 # The init command
+There is some minimal boilerplate that is the same for every new book. It's for this purpose that mdBook includes an `init` command.

+When a `SUMMARY.md` file already exists, the `init` command will first parse it and generate the missing files according to the paths used in the `SUMMARY.md`. This allows you to think and create the whole structure of your book and then let mdBook generate it for you.

 # The test command
 
-It’s nice to be able to ensure that examples in documentation are current.
-mdBook supports a ‘test’ command, which will use Rustdoc to test out examples:
+When writing a book, you sometimes need to automate some tests. For example, [The Rust Programming Book](https://doc.rust-lang.org/stable/book/) uses a lot of code examples that could get outdated.
+Therefore it is very important for them to be able to automatically test these code examples.
 
+mdBook supports a `test` command that will run all available tests in mdBook. At the moment, only one test is available:
+*"Test Rust code examples using Rustdoc"*, but I hope this will be expanded in the future to include more tests like:
+
+- checking for broken links
+- checking for unused files
+- ...
+
+In the future I would like the user to be able to enable / disable test from the `book.json` configuration file and support custom tests.

 $ mdbook test

+## Hiding code lines
+
+There is a feature in mdBook that let's you hide code lines by prepending them with a `#`.

+

+#fn main() {
+    let x = 5;
+    let y = 6;
+
+    println!("{}", x + y);
+#}

+#fn main() {

+    let y = 7;
+
+    println!("{}", x + y);
+#}
+```
+
+**At the moment, this only works for code examples that are annotated with `rust`. Because it would collide with semantics of some programming languages. In the future, we want to make this configurable through the `book.json` so that everyone can benefit from it.**
