+# 30 second howto
+
+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.
+
+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.
+
+
+# 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.
-* Mailing list: vcs-home@lists.madduck.net
+A lot of modern UNIX-based systems offer packages 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.

+works instead of working through the docs.

-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.
+# Usage Examples
-Read INSTALL.md for detailed setup instructions.
+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.
-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.
-# 3 Overview
+| Task | Command |
+| ----------------------------------------------------- | ------------------------------------------------- |
+| _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` |

+| _Add a remote for repository "vim"_ | `vcsh vim remote add origin <remote>` |
+| | `vcsh vim push origin master:master` |

-## 3.1 Comparison to Other Solutions ##
+
+# 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.
-**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
-## 3.2 Default Directory Layout ##
+This is where `mr` comes in. While the use of `mr` is technically
+optional, but it will be an integral part of the proposed system that follows.
+
+## Default Directory Layout
To illustrate, this is what a possible directory structure looks like.

+The files you see in $XDG\_CONFIG\_HOME/mr/available.d are mr configuration files
that contain the commands to manage (checkout, update etc.) a single
repository. vcsh repo configs end in .vcsh, git configs end in .git, etc. This
is optional and your preference. For example, this is what a zsh.vcsh
[$XDG_CONFIG_HOME/vcsh/repo.d/zsh.git]

+$XDG\_CONFIG\_HOME/mr/available.d contains *all available* repositories. Only
files/links present in mr/config.d, however, will be used by mr. That means

be checked out. A simple `mr update` run in $HOME will clone or update those
four repositories listed in config.d.

Finally, ~/.mrconfig will tie together all those single files which will allow
you to conveniently run `mr up` etc. to manage all repositories. It looks like
this:

-$XDG_CONFIG_HOME/vcsh/repo.d is the directory where all git repositories which
+$XDG\_CONFIG\_HOME/vcsh/repo.d is the directory where all git repositories which
are under vcsh's control are located. Since their working trees are configured
to be in $HOME, the files contained in those repositories will be put in $HOME

repositories by running the necessary vcsh commands for you. You may choose not
to use mr, in which case you will have to run those commands manually or by
other means.
-#### A Few Examples ####
To initialize a new repository: `vcsh init zsh`
To interact with a repository, use the regular Git commands, but prepend them
with `vcsh run $repository_name`. For example:
- vcsh run zsh git status
- vcsh run zsh git add -f .zshrc
- vcsh run zsh git commit
+ vcsh zsh status
+ vcsh zsh add .zshrc
+ vcsh zsh commit
Obviously, without mr keeping repositories up-to-date, it will have to be done
manually. Alternatively, you could try something like this:
vcsh run $repo git pull;
done
