+While it may appear that there's an overwhelming amount of documentation and
+while the explanation of the concepts behind `vcsh` needs to touch a few gory
+details of `git` internals, getting started with `vcsh` is extremely simple.

 
 

-* Pull requests or issues on [https://github.com/RichiH/vcsh][vcsh]
+Let's say you want to version control your `vim` configuration:
+
+    vcsh init vim
+    vcsh vim add ~/.vimrc ~/.vim
+    vcsh vim commit -m 'Initial commit of my Vim configuration'
+    # optionally push your files to a remote
+    vcsh vim remote add origin <remote>
+    vcsh vim push -u origin master
+    # from now on you can push additional commits like this
+    vcsh vim push
+
+If all that looks a _lot_ like standard `git`, that's no coincidence; it's
+a design feature.

+# Usage Examples
+
+There are three different ways to interact with `vcsh` repositories; this
+section will only show the simplest and easiest way.
+Certain more advanced use cases require the other two ways, but don't worry
+about this for now. If you never even bother playing with the other two
+modes you will still be fine.
+`vcsh enter` and `vcsh run`  will be covered in later sections.
+
+
+## Initialize a new repository called "vim"
+
+    vcsh init vim
+
+## Clone an existing repository
+
+    vcsh clone <remote> <repository_name>
+
+## Add files to repository "vim"
+
+    vcsh vim add ~/.vimrc ~/.vim
+    vcsh vim commit -m 'Update Vim configuration'
+
+## Add a remote for repository "vim"
+
+    vcsh vim remote add origin <remote>
+    vcsh vim push origin master:master
+    vcsh vim branch --track master origin/master
+
+## Push to remote of repository "vim"
+
+    vcsh vim push
+
+## Pull from remote of repository "vim"
+

 The next logical step is to create single-purpose repositories in, for example,

 The next logical step is to create single-purpose repositories in, for example,

+symlinking the individual repositories.
+
+`vcsh` takes this approach one step further. It enables single-purpose
+repositories and stores them in a hidden directory. However, it does not create
+symbolic links in `$HOME`; it puts the actual files right into `$HOME`.
+
+As `vcsh` allows you to put an arbitrary number of distinct repositories into
+your `$HOME`, you will end up with a lot of repositories very quickly.

 
 

-vcsh takes this second approach one step further. It expects
-single-purpose repositories and stores them in a hidden directory (similar
-to ~/.dotfiles). However, it does not create symbolic links in $HOME; it puts
-the actual files right into $HOME.
+To manage both `vcsh` and other repositories, we suggest using [mr](mr). `mr`
+takes care of pulling in and pushing out new data for a variety of version
+control systems.

 
 

-Furthermore, by making use of [mr] [1], it makes it very easy to enable/disable
-and clone a large number of repositories. The use of mr is technically optional
-(see 4.3), but it will be an integral part of the proposed system that follows.
+`vcsh` was designed with [mr][mr], a tool to manage Multiple Repositories, in
+mind and the two integrate very nicely. `mr` has native support for `vcsh`
+repositories and to `vcsh`, `mr` is just another configuration to track.
+This make setting up any new machine a breeze. It takes literally less than
+five minutes to go from standard installation to fully set up system
