+# Contributing
+
+Want to contribute to Polymer? Great!
+
+We are more than happy to accept external contributions to the project in the form of [feedback](https://groups.google.com/forum/?fromgroups=#!forum/polymer-dev), [bug reports](../../issues), and pull requests.
+
+## Contributor License Agreement
+
+Before we can accept patches, there's a quick web form you need to fill out.
+
+- If you're contributing as an individual (e.g. you own the intellectual property), fill out [this form](http://code.google.com/legal/individual-cla-v1.0.html).
+- If you're contributing under a company, fill out [this form](http://code.google.com/legal/corporate-cla-v1.0.html) instead.
+
+This CLA asserts that contributions are owned by you and that we can license all work under our [license](LICENSE).
+
+Other projects require a similar agreement: jQuery, Firefox, Apache, Node, and many more.
+
+[More about CLAs](https://www.google.com/search?q=Contributor%20License%20Agreement)
+
+## Initial setup
+
+Here's an easy guide that should get you up and running:
+
+1. Setup Grunt: `sudo npm install -g grunt-cli`
+1. Fork the project on github and pull down your copy.
+ > replace the {{ username }} with your username and {{ repository }} with the repository name
+
+ git clone git@github.com:{{ username }}/{{ repository }}.git --recursive
+
+ Note the `--recursive`. This is necessary for submodules to initialize properly. If you don't do a recursive clone, you'll have to init them manually:
+
+ git submodule init
+ git submodule update
+
+ Download and run the `pull-all.sh` script to install the sibling dependencies.
+
+ git clone git://github.com/Polymer/tools.git && tools/bin/pull-all.sh
+
+1. Test your change
+ > in the repo you've made changes to, run the tests:
+
+ cd $REPO
+ npm install
+ grunt test
+
+1. Commit your code and make a pull request.
+
+That's it for the one time setup. Now you're ready to make a change.
+
+## Submitting a pull request
+
+We iterate fast! To avoid potential merge conflicts, it's a good idea to pull from the main project before making a change and submitting a pull request. The easiest way to do this is setup a remote called `upstream` and do a pull before working on a change:
+
+ git remote add upstream git://github.com/Polymer/{{ repository }}.git
+
+Then before making a change, do a pull from the upstream `master` branch:
+
+ git pull upstream master
+
+To make life easier, add a "pull upstream" alias in your `.gitconfig`:
+
+ [alias]
+ pu = !"git fetch origin -v; git fetch upstream -v; git merge upstream/master"
+
+That will pull in changes from your forked repo, the main (upstream) repo, and merge the two. Then it's just a matter of running `git pu` before a change and pushing to your repo:
+
+ git checkout master
+ git pu
+ # make change
+ git commit -a -m 'Awesome things.'
+ git push
+
+Lastly, don't forget to submit the pull request.

The goal is to allow users to avoid the \n most obvious pitfalls and do so without compromising performance significantly. \n For ShadowDOM styling that's not covered here, a set of best practices\n can be provided that should allow users to accomplish more complex styling.\n\n The following is a list of specific ShadowDOM styling features and a brief\n discussion of the approach used to shim.\n\n Shimmed features:\n\n * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n element using the :host rule. To shim this feature, the :host styles are \n reformatted and prefixed with a given scope name and promoted to a \n document level stylesheet.\n For example, given a scope name of .foo, a rule like this:\n \n :host {\n background: red;\n }\n }\n \n becomes:\n \n .foo {\n background: red;\n }\n \n * encapsultion: Styles defined within ShadowDOM, apply only to \n dom inside the ShadowDOM. Polymer uses one of two techniques to imlement\n this feature.\n \n By default, rules are prefixed with the host element tag name \n as a descendant selector. This ensures styling does not leak out of the 'top'\n of the element's ShadowDOM. For example,\n\n div {\n font-weight: bold;\n }\n \n becomes:\n\n x-foo div {\n font-weight: bold;\n }\n \n becomes:\n\n\n Alternatively, if Platform.ShadowCSS.strictStyling is set to true then \n selectors are scoped by adding an attribute selector suffix to each\n simple selector that contains the host element tag name. Each element \n in the element's ShadowDOM template is also given the scope attribute. \n Thus, these rules match only elements that have the scope attribute.\n For example, given a scope name of x-foo, a rule like this:\n \n div {\n font-weight: bold;\n }\n \n becomes:\n \n div[x-foo] {\n font-weight: bold;\n }\n\n Note that elements that are dynamically added to a scope must have the scope\n selector added to them manually.\n\n * upper/lower bound encapsulation: Styles which are defined outside a\n shadowRoot should not cross the ShadowDOM boundary and should not apply\n inside a shadowRoot.\n\n This styling behavior is not emulated. Some possible ways to do this that \n were rejected due to complexity and/or performance concerns include: (1) reset\n every possible property for every possible selector for a given scope name;\n (2) re-implement css in javascript.\n \n As an alternative, users should make sure to use selectors\n specific to the scope in which they are working.\n \n * ::distributed: This behavior is not emulated. It's often not necessary\n to style the contents of a specific insertion point and instead, descendants\n of the host element can be styled selectively. Users can also create an \n extra node around an insertion point and style that node's contents\n via descendent selectors. For example, with a shadowRoot like this:\n \n <style>\n ::content(div) {\n background: red;\n }\n </style>\n <content></content>\n \n could become:\n \n <style>\n / *@polyfill .content-container div * / \n ::content(div) {\n background: red;\n }\n </style>\n <div class=\"content-container\">\n <content></content>\n </div>\n \n Note the use of @polyfill in the comment above a ShadowDOM specific style\n declaration. This is a directive to the styling shim to use the selector \n in comments in lieu of the next selector when running under polyfill.\n*/\n(function(scope) {\n\nvar ShadowCSS = {\n strictStyling: false,\n registry: {},\n // Shim styles for a given root associated with a name and extendsName\n // 1. cache root styles by name\n // 2. optionally tag root nodes with scope name\n // 3. shim polyfill directives /* @polyfill */ and /* @polyfill-rule */\n // 4. shim :host and scoping\n shimStyling: function(root, name, extendsName) {\n var scopeStyles = this.prepareRoot(root, name, extendsName);\n var typeExtension = this.isTypeExtension(extendsName);\n var scopeSelector = this.makeScopeSelector(name, typeExtension);\n // use caching to make working with styles nodes easier and to facilitate\n // lookup of extendee\n var cssText = stylesToCssText(scopeStyles, true);\n cssText = this.scopeCssText(cssText, scopeSelector);\n // cache shimmed css on root for user extensibility\n if (root) {\n root.shimmedStyle = cssText;\n }\n // add style to document\n this.addCssToDocument(cssText, name);\n },\n /*\n * Shim a style element with the given selector.

+# Polymer
+
+[](https://github.com/igrigorik/ga-beacon)
+
+Build Status: [http://build.chromium.org/p/client.polymer/waterfall](http://build.chromium.org/p/client.polymer/waterfall)
+
+## Brief Overview
+
+For more detailed info goto [http://polymer-project.org/](http://polymer-project.org/).
+
+Polymer is a new type of library for the web, designed to leverage the existing browser infrastructure to provide the encapsulation and extendability currently only available in JS libraries.
+
+Polymer is based on a set of future technologies, including [Shadow DOM](https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html), [Custom Elements](https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/custom/index.html) and Model Driven Views. Currently these technologies are implemented as polyfills or shims, but as browsers adopt these features natively, the platform code that drives Polymer evacipates, leaving only the value-adds.
+
+## Tools & Testing
+
+For running tests or building minified files, consult the [tooling information](http://www.polymer-project.org/resources/tooling-strategy.html).

+Each pipe viewer plugin must do a default export of a class that extends the PipeViewer interface.
+
+"builtin" folder contains pipe viewers that come built-in with PipeToBrowser application.
+
+Plugin loader expects the folder and file name to match the viewer's name.

-# Mounttable Browser
-Mountable browser is a browser application that lets the user view and traverse mounttables.
-
-## Building
-Before you can run Mounttable Browser, you need to build. Simply run:
-
-```sh
-make
-```
-or
-
-```sh
-make build
-```
-
-## Running
-
-### Daemons
-Before you can run mounttable browser, a number of servers must be started.
-
-To run these daemons, simply run:
-
-```sh
-make daemons
-```
-
-after the daemons are started, simply open browser/client/client.html in a browser.
