-## 2.1 Comparison to Other Solutions ##
+If all that looks a _lot_ like standard `git`, that's no coincidence; it's
+a design feature.
+
+
+# Introduction
+
+[vcsh][vcsh] allows you to maintain several Git repositories in one single
+directory. They all maintain their working trees without clobbering each other
+or interfering otherwise. By default, all Git repositories maintained via
+`vcsh` store the actual files in `$HOME` but you can override this setting if
+you want to.
+All this means that you can have one repository per application or application
+family, i.e. `zsh`, `vim`, `ssh`, etc. This, in turn, allows you to clone
+custom sets of configurations onto different machines or even for different
+users; picking and mixing which configurations you want to use where.
+For example, you may not need to have your `mplayer` configuration on a server
+or available to root and you may want to maintain different configuration for
+`ssh` on your personal and your work machines.
+
+A lot of modern UNIX-based systems offer pacakges for `vcsh`. In case yours
+does not read `INSTALL.md` for install instructions or `PACKAGING.md` to create
+a package, yourself. If you do end up packaging `vcsh` please let us know so we
+can give you your own packaging branch in the upstream repository.
+
+## Talks
+
+Some people found it useful to look at slides and videos explaining how `vcsh`
+works instead of working through the docs.
+All slides, videos, and further information can be found
+[on the author's talk page][talks].
+
+
+# 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 ewen 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 "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 push origin master:master
+    vcsh vim branch --track master origin/master

+# Overview
+
+## From zero to vcsh
+
+You put a lot of effort into your configuration and want to both protect and
+distribute this configuration.
 
 Most people who decide to put their dotfiles under version control start with a
-**single repository in $HOME**, adding all their dotfiles (and possibly more)
+single repository in `$HOME`, adding all their dotfiles (and possibly more)
 to it. This works, of course, but can become a nuisance as soon as you try to
 manage more than one host.
 
 The next logical step is to create single-purpose repositories in, for example,
-~/.dotfiles and to create **symbolic links in $HOME**. This gives you the
+`~/.dotfiles` and to create symbolic links into `$HOME`. This gives you the
 flexibility to check out only certain repositories on different hosts. The
 downsides of this approach are the necessary manual steps of cloning and
-symlinking the individual repositories. It will probably become a nuisance when
-you try to manage more than two hosts.
+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.
+
+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.
 
-**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**.
+`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
 
-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 3.4), but it will be an integral part of the proposed system that follows.
