+[Twitter Bootstrap](http://twitter.github.com/bootstrap) [![Build Status](https://secure.travis-ci.org/twitter/bootstrap.png)](http://travis-ci.org/twitter/bootstrap)
+=================
+
+This version of Bootstrap is maintained to be only the built version of bootstrap to be used with bower.  If you are looking for the full source of bootstrap go to [bootstrap](https://github.com/twitter/bootstrap)
+
+Bootstrap is a sleek, intuitive, and powerful front-end framework for faster and easier web development, created and maintained by [Mark Otto](http://twitter.com/mdo) and [Jacob Thornton](http://twitter.com/fat) at Twitter.
+
+To get started, checkout http://getbootstrap.com!
+
+
+
+Quick start
+-----------
+
+Clone the repo, `git clone git://github.com/twitter/bootstrap.git`, or [download the latest release](https://github.com/twitter/bootstrap/zipball/master).
+
+
+
+Versioning
+----------
+
+For transparency and insight into our release cycle, and for striving to maintain backward compatibility, Bootstrap will be maintained under the Semantic Versioning guidelines as much as possible.
+
+Releases will be numbered with the following format:
+
+`<major>.<minor>.<patch>`
+
+And constructed with the following guidelines:
+
+* Breaking backward compatibility bumps the major (and resets the minor and patch)
+* New additions without breaking backward compatibility bumps the minor (and resets the patch)
+* Bug fixes and misc changes bumps the patch
+
+For more information on SemVer, please visit http://semver.org/.
+

+
+Developers
+----------
+
+We have included a makefile with convenience methods for working with the Bootstrap library.
+
++ **dependencies**
+Our makefile depends on you having recess, connect, uglify.js, and jshint installed. To install, just run the following command in npm:
+
+```
+$ npm install recess connect uglify-js jshint -g
+```
+
++ **build** - `make`
+Runs the recess compiler to rebuild the `/less` files and compiles the docs pages. Requires recess and uglify-js. <a href="http://twitter.github.com/bootstrap/less.html#compiling">Read more in our docs &raquo;</a>
+
++ **test** - `make test`
+Runs jshint and qunit tests headlessly in [phantomjs](http://code.google.com/p/phantomjs/) (used for ci). Depends on having phantomjs installed.
+
++ **watch** - `make watch`
+This is a convenience method for watching just Less files and automatically building them whenever you save. Requires the Watchr gem.
+
+
+
+Contributing
+------------
+
+Please submit all pull requests against *-wip branches. If your unit test contains javascript patches or features, you must include relevant unit tests. Thanks!

+Getting started
+======
+Connect to your ar drone 2 via WLAN, then run node.server.js open up localhost:3001 and you're ready to go.
+
+Use `W, A, S, D` to move front, back and sideways. Use your `cursors` to go up/down or turn clockwise/counter clockwise.
+Some animations can be triggered with `1-4`
+`SPACE` for taking of and `esc` for landing.
+
+When you crash use `e` to recover from emergency mode.
+
+This project is heavily inspired from https://github.com/usefulthink/nodecopter-monitor . I just removed the three.js part and ported it from socket.io to faye since I like that better.
+
+Dependencies
+=======
+You can install/update the node dependencies via `npm install -d`.
+Dependencies for client code are managed via bower ( https://github.com/twitter/bower ). 
+You need to have `ffmpeg` installed (it's used for the picture stuff)
+
+Screenshot
+========
+This is how it looks like in action:
+![drone browser in chrome](https://raw.github.com/functino/drone-browser/master/screenshot.png)
+
+TODO
+======
+- use getUserMedia/the webcam to control the drone (like magic xylophone...)
+- add a slider to make the speed/duration of actions configurable
+- toggle between takeoff/land buttons or disable takeoff button after takeoff...
+- mayby change the "recover" button to send a land command first (because otherwise the drone tries to start again...)
+- only show the recover button when the drone is in emergency mode
+- use canvas to draw angle-stuff or rotate the picture stream accordingly
+- get rid of the (sometimes) long lag of the picture stream 
+- makte it work without ffmpeg (skip the picture stuff then....)
