 # XOS Styles
 
-Collection of commands to work on xos styling.
+This folder holds style definition for XOS and a collection of tools usefull to work with them.
 
-> _Require to install dependencies with `npm install` before usage_
+## Setup
 
-`npm start` run BrowserSync and `node-sass` in watch mode.
+The best way to work with XOS styling and appearance is to have the `frontend` configuration running locally on your machine. In this way most of the GUI files are shared (see below). To use the provided tools as they are XOS should be available at `http://xos.dev:9999`.
 
->NOTE _Require XOS to respond on `http:xos.dev:999`_
\ No newline at end of file
+Before start working on the UI you should also install the dependencies, so enter `xos/views/style/` and execute `npm install` (NodeJs is required).
+
+## Developing
+
+When your environment is ready you could start it with `npm start`, this command will:
+  - Whatch styles in `xos/views/style/sass` and compile them on change
+  - Reload the broser on file changes (for more details see `xos/views/style/bs-config.js`)
+
+## Shared files:
+Shared files are defined in `xos/configurations/frontend/docker-compose.yml`, for the `frontend` configuration they are:
+```
+  - ../common/xos_common_config:/opt/xos/xos_configuration/xos_common_config
+  - ../../core/xoslib:/opt/xos/core/xoslib
+  - ../../core/static:/opt/xos/core/static

 ### DevStack
 
-The following instructions can be used to install DevStack and XOS together
-on a single node.  This setup has been run successfully in a VirtualBox VM
-with 2 CPUs and 4096 GB RAM.
-
-First, if you happen to be installing DevStack on a CloudLab node, you can
-configure about 1TB of unallocated disk space for DevStack as follows:
+On a server with a fresh Ubuntu 14.04 install, 
+[this script](https://raw.githubusercontent.com/open-cloud/xos/master/xos/configurations/common/devstack/setup-devstack.sh)
+can be used to bootstrap a single-node DevStack environment that can be used
+for basic XOS development.
+The script installs DevStack and checks out the XOS repository.  Run the script
+and then invoke the XOS configuration for DevStack as follows:
 ```
-~$ sudo mkdir -p /opt/stack
-~$ sudo /usr/testbed/bin/mkextrafs /opt/stack
-```
-
-To install DevStack and XOS:
-
-```
-~$ git clone https://github.com/open-cloud/xos.git
-~$ git clone https://git.openstack.org/openstack-dev/devstack
-~$ cd devstack
-~/devstack$ cp ../xos/xos/configurations/common/devstack/local.conf .
-~/devstack$ ./stack.sh
-~/devstack$ cd ../xos/xos/configurations/devel/
+~$ wget https://raw.githubusercontent.com/open-cloud/xos/master/xos/configurations/common/devstack/setup-devstack.sh
+~$ bash ./setup-devstack.sh
+~$ cd ../xos/xos/configurations/devel/
 ~/xos/xos/configurations/devel$ make devstack
 ```
 
+This setup has been run successfully in a VirtualBox VM with 2 CPUs and 4096 GB RAM.
+However it is recommended to use a dedicated server with more resources.
+
+**NOTE: If your goal is to create a development environment for [CORD](http://opencord.org/), 
+DevStack is not what you want.  Look at the [cord-pod](../cord-pod) configuration instead!**
+
 ## What you get
