Download Emacs and extract to C:\emacs You'll end up with something like:

C:
    |->emacs
        |->bin
        |->etc
        |->info
        |->leim
        |->lisp
        |->site-lisp

Set up the HOME environment variable. This is where your .emacs file and .emacs.d directory will go.

Create the folder packages inside .emacs.d.

Emacs' load-path variable specifies the load path. Check it with C-h v load-path.

Add regedit Key [HKEY_CLASSES_ROOT/*/shell/Edit with Emacs/command] with the default value "C:\emacs\bin\runemacs.exe" %1

Add a shortcut to C:\emacs\bin\runemacs.exe called emacs, inside C:\Windows. Make sure that it says "Start in: C:\users\destradaa"

Markdown mode: download markdown-mode.el and put it inside ~/.emacs.d/packages/.

Auto complete mode: download the zip, extract it and load-file the file etc/install.el.

If you are behind a proxy, put this in your .emacs file:

(setq url-proxy-services '(("no_proxy" . "localhost")
                                                 ("http" . "proxy.work.com:8080")))

Paste this in the scratchpad and do eval-buffer:

(package-install 'helm)
(package-install 'js2-mode)
(package-install 'rainbow-mode)
(package-install 'yasnippet)
