+# 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` are stored 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.
+
+`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

 
 

-* Mailing list: http://lists.madduck.net/listinfo/vcs-home
+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.

-vcsh allows you to have several git repositories, all maintaining their working
-trees in $HOME without clobbering each other. That, in turn, means you can have
-one repository per config set (zsh, vim, ssh, etc), picking and choosing which
-configs you want to use on which machine.

 
 

-vcsh was designed with [mr] [1] in mind so you might want to install that, as
-well.
+# 30 second howto

 
 

-Read INSTALL.md for detailed setup instructions.
+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.

 
 

-The following overview will try to give you an idea of the use cases and
-advantages of vcsh. See sections 3 and 4 for detailed instructions and
-examples.
+Let's say you want to version control your `vim` configuration:

 
 

-## 2.1 Talks ##
+    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

 
 

-Some people found it useful to look at slides and videos explaining how vcsh works.
-They can all be found at [here](http://richardhartmann.de/talks/).
+If all that looks a _lot_ like standard `git`, that's no coincidence; it's
+a design feature.

 The next logical step is to create single-purpose repositories in, for example,
 to it. This works, of course, but can become a nuisance as soon as you try to

+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.
