# Introduction

`Spacemacs` is a user-friendly and well-documented Emacs Advanced kit.

`Advanced` means here that it heavily and happily performs non-trivial tweaks
and customization in order to make itself easy to use and unique.

`Advanced` does not mean that you have to be an advanced Emacs user, beginners
are welcome and encouraged to use `Spacemacs` since it provides a simple
architecture to contribute changes and hack others contributions.

Its status is `beta` for now, essentially because of the configuration system
that is not yet finished but already usable.

And now, to use a well known catch line from [Emacs Live][emacs_live]:

    M-x start-spacing !

# Features

### Convenient and Mnemonic Key Bindings

`Spacemacs` organizes key bindings by mnemonic namespaces. If you are looking
for commands to operate on your buffer, they are right under `<SPC> b`, if you
want to operate on your project, then it is `<SPC> p`, etc...

There is no need to learn convoluted Emacs chords, everything you need is under
bindings that are easy to type and easy to remember.

### Excellent Evil Support

Spacemacs comes with Vim modal editing through [Evil Mode][]. Everything is
designed with it in mind from the key bindings to the user interface.
This includes fancy goodies like a micro-state for editing all occurences of a
symbol and extra packages like [ace-jump][],[evil-lisp-state][] and [evil-nerd-commenter][].

### Batteries Included

Comes with configuration for hundreds of packages that make it fantastic out of the
box. Many languages like Python, Ruby, Scala, R, SCSS, Elixir and Javascript come with modes,
configuration and convenient key bindings. It also comes with [Git support][], [project management][]
and auto-completion. And all of this is optimized and lazy-loaded so you still get fast boot times!

And if that isn't enough you can use [community contributed][contrib layers] configuration
layers for nice configurations of packages that aren't in the default distribution.

### Great [Documentation][DOCUMENTATION.MD]

Most Spacemacs features come with extensive documentation including key bindings, configuration options and
explanations for beginners. And if you can't find the answers you need, ask your question in the [Gitter Chat][] and
a member of the community will help you out.

### Nice UI

Spacemacs is designed to look nice in a minimal and functional way. It comes with good theme support and a highly customized
Powerline. The Powerline includes features like quick window switching numbers, Evil mode colors, and nice mode icons.

# Prerequisites

`Spacemacs` is tested with Emacs 24.3 and 24.4. It should boot on all the major
OSes where these versions can be installed.

# Install

1) Backup your current `~/.emacs.d` and clone the repo _with the submodules_:

    cd ~
    mv .emacs.d .emacs.bak
    git clone --recursive http://github.com/syl20bnr/spacemacs ~/.emacs.d

`master` is a stable branch, if you want the "bleeding edge" checkout the
`develop` branch.

2) Launch Emacs, the first time a bunch of packages will be downloaded and
installed. When the package installation is complete restart Emacs and
`Spacemacs` should be ready to use.

In case of failure see [troubleshoot section][troubleshoot] in documentation.

# Configuration

## Configuration layers

`Spacemacs` is based on [configuration layers][config]. To create your own
configuration layer:

    <SPC> : config-system/create-layer RET

After entering a name, a layer skeleton will be created in the [private][]
directory. The `private` directory is ignored by Git.

To use your newly created configuration layer, add it to your `~/.spacemacs`
file (see next section).

## Dotfile ~/.spacemacs

`Spacemacs` has a convenient dotfile. You have to install it by invoking the
following command inside Emacs:

    <SPC> : dotspacemacs/install RET

Refers directly to the file `~/.spacemacs` to get documentation or
navigate to the [dotfile configuration][dotfile] section of [DOCUMENTATION.md][].

# Contributions

To consult the contribution guidelines go to [CONTRIBUTE.md][].

# Help commands

## Key bindings

1) By default, [guide-key][] and [guide-key-tip][] are enabled.

Whenever you press a prefix command (like `<SPC>`) and wait for one second,
a buffer appear listing the possible keys following this prefix.

2) You can also easily get a full list of all the key bindings by pressing:

    <SPC> ?

To narrow the list to `Spacemacs` specific key bindings set the pattern to
something like the regular expression:

    `^SPC\ b`

The example above will list all the `buffer` related bindings.

## Other describe functions

Emacs `describe-xxx` function are accessible with the following bindings:

Key Binding   |                 Description
--------------|------------------------------------------------------------------
`<SPC> h d f` | describe-function
`<SPC> h d k` | describe-key
`<SPC> h d m` | describe-mode
`<SPC> h d v` | describe-variable
