-### New nodes
-
-The plugin nature of Node-RED means anyone can create a new node to extend
-its capabilities.
-
-We want to avoid duplication as that can lead to confusion. Many of our existing
-nodes offer a starting point of functionality. If they are missing features,
-we would rather extend them than add separate 'advanced' versions. But the key
-to that approach is getting the UX right to not lose the simplicity.
-
-To contribute a new node, please raise a pull-request against the 
-`node-red-nodes` repository.
-
-Eventually, the nodes will be npm-installable, but we're not there yet. We'll
-also have some sort of registry of nodes to help with discoverability.

-### Coding standards

-Please ensure you follow the coding standards used through-out the existing

-Node-RED Install
-================
-
-## Install node.js
-
-You can get the latest version from <http://nodejs.org/download/>.
-
-Or, you may want to use a version from your operating system's package manager:
- <https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager>
-
-## Get Node-RED
-
-Clone the repository from GitHub:
-
-    $ git clone git@github.com:node-red/node-red.git
-
-## Install the pre-requisite modules
-
-From the top-level directory of Node-RED, run:
-
-    $ npm install
-
-This will install the core pre-requisite modules.
-
-## Run Node-RED
-
-From the top-level directory, run:
-
-    $ node red.js
-
-You can then access Node-RED at <http://localhost:1880>.
-
-Online documentation is available at <http://nodered.org/docs>.
-
-## Installing individual node dependencies
-
-When Node-RED starts, it attempts to load the nodes from the `nodes/` directory.
-Each will have its own set of dependencies that will need to be installed before
-the node is available in the palette.
-
-To help identify the dependencies, Node-RED logs any modules it fails to find
-for a particular node. You don't have to install these unless you want or need
-that node to appear.
-
-Alternatively, a node's `.js` file can be examined to identify the modules it
-explicitly requires. For example, the Twitter node is defined in
-`nodes/social/27-twitter.js` and contains:
-
-	var RED = require("../../red/red");
-	var ntwitter = require('ntwitter');
-	var OAuth= require('oauth').OAuth;
-
-Of these, `ntwitter` and `oauth` are neither built-in modules nor ones provided
-by Node-RED itself. They can subsequently be installed by running:
-
-    $ npm install ntwitter oauth
-

-## Documentation
+## Getting Help
 
 More documentation can be found [here](http://nodered.org/docs).
 
-For further help, or general discussion, there is also a [mailing list](https://groups.google.com/forum/#!forum/node-red).

-## Browser Support
+## Developers
 
-The Node-RED editor runs in the browser. We routinely develop and test using
-Chrome and Firefox. We have anecdotal evidence that it works in IE9.
+If you want to run the latest code from git, here's how to get started:
 
-We do not yet support mobile browsers, although that is high on our priority
-list.
+1. Install grunt, the build tool
+
+        npm install -g grunt-cli
+
+2. Clone the code:
+
+        git clone https://github.com/node-red/node-red.git
+        cd node-red
+
+3. Install the node-red dependencies
+
+        npm install
+
+4. Build the code
+
+        grunt build
+
+5. Run
+
+        node red.js
