 # Changelog
 
+## 0.13.0 (2015-06-18)
+
+- Split install scripts into two pieces: prerequisites installation (optional) and actual box installation.
+- Automatic installation is now supported on Windows!
+- vhost-proxy service - adds ability to use a single shared IP address for multiple web projects running concurently.
+- VirtualBox network adapters performance adjustments (using `virtio` on the NAT interface). Resolves #12.
+- Added bash to avoid shell script compatibility issues and updated all shell scripts to use `#/bin/bash` header. Resolves #17.
+- Documentation updates.

 Boot2docker Vagrant box for optimized Docker and Docker Compose use on Mac and Windows.
 
 ## What is this?

+This is a temporary solution to achieve better performance with synced folders and docker data volumes on Mac and Windows.  
 The stock boot2docker currently mounts host volumes via the default VirtualBox Guest Additions (vboxfs) mode, which is terribly slow. Much better performance can be achieved with NFS, SMB or rsync.
 
 <a name="requirements"></a>
-## Requirements
+## Prerequisites
 1. [VirtualBox](https://www.virtualbox.org/) 4.3.20+
 2. [Vagrant](https://www.vagrantup.com/) 1.6.3+
 3. [Git](http://git-scm.com/)
 
+Proceed to [Setup and usage](#setup) if you already have all prerequisites installed or prefer to install some/all manually.  
+Automatic installation of prerequisites is available via the following one-liners.
+
+**Mac**
+
+On Mac prerequisites are installed using **brew/cask** (brew and cask will be installed if missing).
+
+    curl -s https://raw.githubusercontent.com/blinkreaction/boot2docker-vagrant/master/presetup-mac.sh | bash
+
+**Windows**
+
+On Windows prerequisites are installed using **chocolatey** (chocolatey will be installed if missing).
+
+1. Run Command Prompt as administrator
+2. Copy and and paste there the code from [presetup-win.cmd](https://raw.githubusercontent.com/blinkreaction/boot2docker-vagrant/master/presetup-win.cmd)

 ## Setup and usage
 
-### Automatic installation (Mac only)
+### Automatic installation (Mac and Windows)
 
-The following tools will be installed: brew, cask, virtualbox, vagrant, docker, docker-compose.
-In case you already have some of these installed (virtualbox, vagrant), it may be best (though not required) to either follow the manual install process or uninstall them before proceeding.
+**On Windows** Git Bash is the recommended option to run console commands.
+If you are having any issues, please check if they can be reproduced in Git Bash.
 
 Run the following command within your `<Projects>` (shared boo2docker VM for multiple projects, recommended) or `<Project>` (dedicated boot2docker VM) directory:

 Project specific `<IP>:<port>` mapping for containers is done in via docker-compose in `docker-compose.yml`
 
+# vhost-proxy
+
+As an alternative to using dedicated IPs for different projects a built-in vhost-proxy container can be used.  
+It binds to `192.168.10.10:80` (the default box IP address) and routes web requests based on the `Host` header.
+
+### How to use
+- Set `vhost_proxy: true` in your vagrant.yml file and do a 'vagrant reload'
+- Set the `VIRTUAL_HOST` environment variable for the web container in your setup (e.g. `VIRTUAL_HOST=example.com`)
+- Add an entry in your hosts file (e.g. `/etc/hosts`) to point the domain to the default box IP (`192.168.10.10`)
+
+Example docker run
+
+```
+docker run --name nginx -d -e "VIRTUAL_HOST=example.com" nginx:latest
+```
+
+Example docker-compose.yml entry
+
+```
+# Web node
+web:
+  image: nginx:latest
+  ports:
+    - "80"
+  environment:
+    - VIRTUAL_HOST=example.com
+```
+
+Example hosts file entry
+
+```
+192.168.10.10  example.com
+```
+
+It is completely fine to use both the vhost-proxy approach and the dedicated IPs approach concurently:
+ - `"80"` - expose port "80", docker will randomly pick an available port on the Docker Host
+ - `"192.168.10.11:80:80"` - dedicated IP:port mapping
+
