+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at h5bp@htmlcssjavascript.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [https://contributor-covenant.org/version/1/4][version]

+- [ ] bug report
+- [ ] feature request
+- [ ] other (Please do not submit support requests here (below))
+
+## Notes:
+
+* Please **do not** use the issue tracker for personal support requests (use
+  [Stack Overflow](https://stackoverflow.com/questions/tagged/html5boilerplate)).
+
+* Please **do not** derail or troll issues. Keep the discussion on topic and
+  respect the opinions of others.
+
+* Please **do not** open issues or pull requests regarding the code in

+  their respective repositories).
+
+## Bug reports
+
+A bug is a _demonstrable problem_ that is caused by the code in the repository.
+Good bug reports are extremely helpful - thank you!
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** &mdash; check if the issue has already been
+   reported.
+
+   We have a long history of sometimes _very_ detailed discussion of every line of code
+   in the project. We want discussion, so it might still warrant an issue. It
+   just helps to get the (sometimes extensive) context.
+
+2. **Check if the issue has been fixed** &mdash; try to reproduce it using the
+   latest `master` or development branch in the repository.
+
+3. **Isolate the problem** &mdash; ideally create a [reduced test
+   case](https://css-tricks.com/reduced-test-cases/) and a live example.
+
+A good bug report shouldn't leave others needing to chase you up for more
+information. Please try to be as detailed as possible in your report. What is
+your environment? What steps will reproduce the issue? What browser(s) and OS
+experience the problem? What would you expect to be the outcome? All these
+details will help people to fix any potential bugs.
+
+Example:
+
+> Short and descriptive example bug report title
+>
+> A summary of the issue and the browser/OS environment in which it occurs. If
+> suitable, include the steps required to reproduce the bug.
+>
+> 1. This is the first step
+> 2. This is the second step
+> 3. Further steps, etc.
+>
+> `<url>` - a link to the reduced test case
+>
+> Any other information you want to share that is relevant to the issue being
+> reported. This might include the lines of code that you have identified as
+> causing the bug, and potential solutions (and your opinions on their
+> merits).
+
+
+## Feature requests
+
+Feature requests are welcome. But take a moment to find out whether your idea
+fits with the scope and aims of the project. It's up to *you* to make a strong
+case to convince the project's developers of the merits of this feature. Please
+provide as much detail and context as possible.

-You are free and even encouraged to modify or add to these base styles as your
-project requires.
-
-
-## Common helpers
-
-Along with the base styles, we also provide some commonly used helper classes.
-
-#### `.hidden`
-
-The `hidden` class can be added to any element that you want to hide visually
-and from screen readers. It could be an element that will be populated and
-displayed later, or an element you will hide with JavaScript.
-
-#### `.visuallyhidden`
-
-The `visuallyhidden` class can be added to any element that you want to hide
-visually, while still have its content accessible to screen readers.
-
-See also:
-
-* [CSS in Action: Invisible Content Just for Screen Reader
-  Users](http://www.webaim.org/techniques/css/invisiblecontent/)
-* [Hiding content for
-  accessibility](http://snook.ca/archives/html_and_css/hiding-content-for-accessibility)
-* [HTML5 Boilerplate - Issue #194](https://github.com/h5bp/html5-boilerplate/issues/194/).
-
-#### `.invisible`
-
-The `invisible` class can be added to any element that you want to hide
-visually and from screen readers, but without affecting the layout.
-
-As opposed to the `hidden` class that effectively removes the element from the
-layout, the `invisible` class will simply make the element invisible while
-keeping it in the flow and not affecting the positioning of the surrounding
-content.
-
-__N.B.__ Try to stay away from, and don't use the classes specified above for
-[keyword stuffing](https://en.wikipedia.org/wiki/Keyword_stuffing) as you will
-harm your site's ranking!
-
-#### `.clearfix`
-
-The `clearfix` class can be added to any element to ensure that it always fully
-contains its floated children.
-
-Over the years there have been many variants of the clearfix hack, but currently,
-we use the [micro clearfix](http://nicolasgallagher.com/micro-clearfix-hack/).
-
-
-## Media Queries
-
-HTML5 Boilerplate makes it easy for you to get started with a
-[_mobile first_](http://www.lukew.com/presos/preso.asp?26) and [_responsive web
-design_](http://www.alistapart.com/articles/responsive-web-design/) approach to
-development. But it's worth remembering that there are [no silver
-bullets](http://blog.cloudfour.com/css-media-query-for-mobile-is-fools-gold/).
-
-We include placeholder media queries to help you build up your mobile styles for
-wider viewports and high-resolution displays. It's recommended that you adapt
-these media queries based on the content of your site rather than mirroring the
-fixed dimensions of specific devices.
-
-If you do not want to take the _mobile first_ approach, you can simply edit or
-remove these placeholder media queries. One possibility would be to work from
-wide viewports down, and use `max-width` media queries instead (e.g.:
-`@media only screen and (max-width: 480px)`).
-
-For more features that can help you in your mobile web development, take a look
-into our [Mobile Boilerplate](https://github.com/h5bp/mobile-boilerplate).
-
-
-## Print styles
-
-Lastly, we provide some useful print styles that will optimize the printing
-process, as well as make the printed pages easier to read.
-
-At printing time, these styles will:
-
-* strip all background colors, change the font color to black, and remove the
-  `text-shadow` — done in order to [help save printer ink and speed up the
-  printing process](http://www.sanbeiji.com/archives/953)
-* underline and expand links to include the URL — done in order to allow users
-  to know where to refer to<br>
-  (exceptions to this are: the links that are
-  [fragment identifiers](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#attr-href),
-  or use the
-  [`javascript:` pseudo protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/void#JavaScript_URIs))
-* expand abbreviations to include the full description — done in order to allow
-  users to know what the abbreviations stands for
-* provide instructions on how browsers should break the content into pages and
-  on [orphans/widows](https://en.wikipedia.org/wiki/Widows_and_orphans), namely,
-  we instruct
-  [supporting browsers](https://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28Cascading_Style_Sheets%29#Grammar_and_rules)
-  that they should:
-
-  * ensure the table header (`<thead>`) is [printed on each page spanned by the
-    table](http://css-discuss.incutio.com/wiki/Printing_Tables)
-  * prevent block quotations, preformatted text, images and table rows from
-    being split onto two different pages
-  * ensure that headings never appear on a different page than the text they
-    are associated with
-  * ensure that
-    [orphans and widows](https://en.wikipedia.org/wiki/Widows_and_orphans) do
-    [not appear on printed pages](https://css-tricks.com/almanac/properties/o/orphans/)
-
-The print styles are included along with the other `css` to [avoid the
-additional HTTP request](http://www.phpied.com/delay-loading-your-print-css/).
-Also, they should always be included last, so that the other styles can be
-overwritten.
+These styles are included in [main.css](https://github.com/h5bp/html5-boilerplate/blob/master/dist/css/main.css). See the [main.css](https://github.com/h5bp/main.css) project [documentation](https://github.com/h5bp/main.css/blob/master/README.md#features) for a full discussion of these styles.

 ### Why is the Google Analytics code at the bottom? Google recommends it be placed in the `<head>`.
 
 The main advantage of placing it in the `<head>` is that you will track the
 user's `pageview` even if they leave the page before it has been fully loaded.
-However, having the code at the bottom of the page [helps improve
-performance](https://stevesouders.com/efws/inline-scripts-bottom.php).

-### How can I integrate [Bootstrap](http://getbootstrap.com/) with HTML5 Boilerplate?
-
-One simple way is to use [Initializr](http://www.initializr.com/) and create a
-custom build that includes both HTML5 Boilerplate and
-[Bootstrap](http://getbootstrap.com/).
-
-Read more about how [HTML5 Boilerplate and Bootstrap complement each
-other](https://www.quora.com/Is-Bootstrap-a-complement-or-an-alternative-to-HTML5-Boilerplate-or-viceversa/answer/Nicolas-Gallagher).
 
+Here's a handy quote from [Mathias Bynens](https://mathiasbynens.be/notes/async-analytics-snippet#comment-50) about our placement choice.
+>I should point out that it’s Google — not me — recommending to place this
+script before all other scripts in the document. The only real advantage is to
+catch a pageView call if your page fails to load completely (for example, if
+the user aborts loading, or quickly closes the page, etc.). Personally, I
+wouldn’t count that as a page view, so I actually prefer to place this script
+at the bottom, after all other scripts. This keeps all the scripts together and
+reinforces that scripts at the bottom are the right move. (Usually I
+concatenate and minify all my scripts into one .js file — the GA snippet being
+the suffix.)

-visitor is using, let's say, Internet Explorer 9, it's possible that IE will not
-use the latest rendering engine, and instead, decide to render your page using
-the Internet Explorer 5.5 rendering engine.
-
-Specifying the `x-ua-compatible` meta tag:

+for details.
+
+## Web App Manifest
+
+HTML5 Boilerplate includes a simple web app manifest file. 
+
+The web app manifest is a simple JSON file that allows you to control how your 
+app appears on a device's home screen, what it looks like when it launches
+in that context and what happens when it is launched. This allows for much greater
+control over the UI of a saved site or web app on a mobile device. 
+
+It's linked to from the HTML as follows:
+
+```html
+        <link rel="manifest" href="site.webmanifest">
+```
+Our [site.webmanifest](https://github.com/h5bp/html5-boilerplate/blob/master/src/site.webmanifest) contains a very skeletal "app" definition, just to show the basic usage. 
+You should fill this file out with [more information about your site or application](https://developer.mozilla.org/en-US/docs/Web/Manifest)
+
 ## Favicons and Touch Icon
 
-The shortcut icons should be put in the root directory of your site. HTML5
+The shortcut icons should be put in the root directory of your site. `favicon.ico` 
+is automatically picked up by browsers if it's placed in the root.  HTML5
 Boilerplate comes with a default set of icons (include favicon and one Apple
 Touch Icon) that you can use as a baseline to create your own.
 
 Please refer to the more detailed description in the [Extend section](extend.md)
 of these docs.
 
-## Modernizr
-
-HTML5 Boilerplate uses a custom build of Modernizr.
-
-[Modernizr](http://modernizr.com) is a JavaScript library which adds classes to
-the `html` element based on the results of feature test and which ensures that
-all browsers can make use of HTML5 elements (as it includes the HTML5 Shiv).
-This allows you to target parts of your CSS and JavaScript based on the
-features supported by a browser.
-
-In general, in order to keep page load times to a minimum, it's best to call
-any JavaScript at the end of the page because if a script is slow to load
-from an external server it may cause the whole page to hang. That said, the
-Modernizr script *needs* to run *before* the browser begins rendering the page,
-so that browsers lacking support for some of the new HTML5 elements are able to
-handle them properly. Therefore the Modernizr script is the only JavaScript
-file synchronously loaded at the top of the document.
-
-## What about polyfills?
-
-If you need to include [polyfills](https://remysharp.com/2010/10/08/what-is-a-polyfill)
-in your project, you must make sure those load before any other JavaScript. If you're
-using some polyfill CDN service, like [cdn.polyfill.io](https://cdn.polyfill.io/),
-just put it before the other scripts in the bottom of the page:
-
-```html
-    <script src="https://cdn.polyfill.io/v1/polyfill.min.js"></script>
-    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

-</body>
-```
-
-If you like to just include the polyfills yourself, you could include them in
-`js/plugins.js`. When you have a bunch of polyfills to load in, you could
-also create a `polyfills.js` file in the `js/vendor` directory. Also using
-this technique, make sure the polyfills are all loaded before any other
-Javascript.
-
-There are some misconceptions about Modernizr and polyfills. It's important
-to understand that Modernizr just handles feature checking, not polyfilling
-itself. The only thing Modernizr does regarding polyfills is that the team

-You are free and even encouraged to modify or add to these base styles as your
-project requires.
-
-
-## Common helpers
-
-Along with the base styles, we also provide some commonly used helper classes.
-
-#### `.hidden`
-
-The `hidden` class can be added to any element that you want to hide visually
-and from screen readers. It could be an element that will be populated and
-displayed later, or an element you will hide with JavaScript.
-
-#### `.visuallyhidden`
-
-The `visuallyhidden` class can be added to any element that you want to hide
-visually, while still have its content accessible to screen readers.
-
-See also:
-
-* [CSS in Action: Invisible Content Just for Screen Reader
-  Users](http://www.webaim.org/techniques/css/invisiblecontent/)
-* [Hiding content for
-  accessibility](http://snook.ca/archives/html_and_css/hiding-content-for-accessibility)
-* [HTML5 Boilerplate - Issue #194](https://github.com/h5bp/html5-boilerplate/issues/194/).
-
-#### `.invisible`
-
-The `invisible` class can be added to any element that you want to hide
-visually and from screen readers, but without affecting the layout.
-
-As opposed to the `hidden` class that effectively removes the element from the
-layout, the `invisible` class will simply make the element invisible while
-keeping it in the flow and not affecting the positioning of the surrounding
-content.
-
-__N.B.__ Try to stay away from, and don't use the classes specified above for
-[keyword stuffing](https://en.wikipedia.org/wiki/Keyword_stuffing) as you will
-harm your site's ranking!
-
-#### `.clearfix`
-
-The `clearfix` class can be added to any element to ensure that it always fully
-contains its floated children.
-
-Over the years there have been many variants of the clearfix hack, but currently,
-we use the [micro clearfix](http://nicolasgallagher.com/micro-clearfix-hack/).
-
-
-## Media Queries
-
-HTML5 Boilerplate makes it easy for you to get started with a
-[_mobile first_](http://www.lukew.com/presos/preso.asp?26) and [_responsive web
-design_](http://www.alistapart.com/articles/responsive-web-design/) approach to
-development. But it's worth remembering that there are [no silver
-bullets](http://blog.cloudfour.com/css-media-query-for-mobile-is-fools-gold/).
-
-We include placeholder media queries to help you build up your mobile styles for
-wider viewports and high-resolution displays. It's recommended that you adapt
-these media queries based on the content of your site rather than mirroring the
-fixed dimensions of specific devices.
-
-If you do not want to take the _mobile first_ approach, you can simply edit or
-remove these placeholder media queries. One possibility would be to work from
-wide viewports down, and use `max-width` media queries instead (e.g.:
-`@media only screen and (max-width: 480px)`).
-
-For more features that can help you in your mobile web development, take a look
-into our [Mobile Boilerplate](https://github.com/h5bp/mobile-boilerplate).
-
-
-## Print styles
-
-Lastly, we provide some useful print styles that will optimize the printing
-process, as well as make the printed pages easier to read.
-
-At printing time, these styles will:
-
-* strip all background colors, change the font color to black, and remove the
-  `text-shadow` — done in order to [help save printer ink and speed up the
-  printing process](http://www.sanbeiji.com/archives/953)
-* underline and expand links to include the URL — done in order to allow users
-  to know where to refer to<br>
-  (exceptions to this are: the links that are
-  [fragment identifiers](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#attr-href),
-  or use the
-  [`javascript:` pseudo protocol](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/void#JavaScript_URIs))
-* expand abbreviations to include the full description — done in order to allow
-  users to know what the abbreviations stands for
-* provide instructions on how browsers should break the content into pages and
-  on [orphans/widows](https://en.wikipedia.org/wiki/Widows_and_orphans), namely,
-  we instruct
-  [supporting browsers](https://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28Cascading_Style_Sheets%29#Grammar_and_rules)
-  that they should:
-
-  * ensure the table header (`<thead>`) is [printed on each page spanned by the
-    table](http://css-discuss.incutio.com/wiki/Printing_Tables)
-  * prevent block quotations, preformatted text, images and table rows from
-    being split onto two different pages
-  * ensure that headings never appear on a different page than the text they
-    are associated with
-  * ensure that
-    [orphans and widows](https://en.wikipedia.org/wiki/Widows_and_orphans) do
-    [not appear on printed pages](https://css-tricks.com/almanac/properties/o/orphans/)
-
-The print styles are included along with the other `css` to [avoid the
-additional HTTP request](http://www.phpied.com/delay-loading-your-print-css/).
-Also, they should always be included last, so that the other styles can be
-overwritten.
+These styles are included in [main.css](https://github.com/h5bp/html5-boilerplate/blob/master/dist/css/main.css). See the [main.css](https://github.com/h5bp/main.css) project [documentation](https://github.com/h5bp/main.css/blob/master/README.md#features) for a full discussion of these styles.

 ### Why is the Google Analytics code at the bottom? Google recommends it be placed in the `<head>`.
 
 The main advantage of placing it in the `<head>` is that you will track the
 user's `pageview` even if they leave the page before it has been fully loaded.
-However, having the code at the bottom of the page [helps improve
-performance](https://stevesouders.com/efws/inline-scripts-bottom.php).

-### How can I integrate [Bootstrap](http://getbootstrap.com/) with HTML5 Boilerplate?
-
-One simple way is to use [Initializr](http://www.initializr.com/) and create a
-custom build that includes both HTML5 Boilerplate and
-[Bootstrap](http://getbootstrap.com/).
-
-Read more about how [HTML5 Boilerplate and Bootstrap complement each
-other](https://www.quora.com/Is-Bootstrap-a-complement-or-an-alternative-to-HTML5-Boilerplate-or-viceversa/answer/Nicolas-Gallagher).
 
+Here's a handy quote from [Mathias Bynens](https://mathiasbynens.be/notes/async-analytics-snippet#comment-50) about our placement choice.
+>I should point out that it’s Google — not me — recommending to place this
+script before all other scripts in the document. The only real advantage is to
+catch a pageView call if your page fails to load completely (for example, if
+the user aborts loading, or quickly closes the page, etc.). Personally, I
+wouldn’t count that as a page view, so I actually prefer to place this script
+at the bottom, after all other scripts. This keeps all the scripts together and
+reinforces that scripts at the bottom are the right move. (Usually I
+concatenate and minify all my scripts into one .js file — the GA snippet being
+the suffix.)

+for details.
+
+## Web App Manifest
+
+HTML5 Boilerplate includes a simple web app manifest file. 
+
+The web app manifest is a simple JSON file that allows you to control how your 
+app appears on a device's home screen, what it looks like when it launches
+in that context and what happens when it is launched. This allows for much greater
+control over the UI of a saved site or web app on a mobile device. 
+
+It's linked to from the HTML as follows:
+
+```html
+        <link rel="manifest" href="site.webmanifest">
+```
+Our [site.webmanifest](https://github.com/h5bp/html5-boilerplate/blob/master/src/site.webmanifest) contains a very skeletal "app" definition, just to show the basic usage. 
+You should fill this file out with [more information about your site or application](https://developer.mozilla.org/en-US/docs/Web/Manifest)
+
 ## Favicons and Touch Icon
 
-The shortcut icons should be put in the root directory of your site. HTML5
+The shortcut icons should be put in the root directory of your site. `favicon.ico` 
+is automatically picked up by browsers if it's placed in the root.  HTML5
 Boilerplate comes with a default set of icons (include favicon and one Apple
 Touch Icon) that you can use as a baseline to create your own.
 
 Please refer to the more detailed description in the [Extend section](extend.md)
 of these docs.
 
-## Modernizr
-
-HTML5 Boilerplate uses a custom build of Modernizr.
-
-[Modernizr](http://modernizr.com) is a JavaScript library which adds classes to
-the `html` element based on the results of feature test and which ensures that
-all browsers can make use of HTML5 elements (as it includes the HTML5 Shiv).
-This allows you to target parts of your CSS and JavaScript based on the
-features supported by a browser.
-
-In general, in order to keep page load times to a minimum, it's best to call
-any JavaScript at the end of the page because if a script is slow to load
-from an external server it may cause the whole page to hang. That said, the
-Modernizr script *needs* to run *before* the browser begins rendering the page,
-so that browsers lacking support for some of the new HTML5 elements are able to
-handle them properly. Therefore the Modernizr script is the only JavaScript
-file synchronously loaded at the top of the document.
-
-## What about polyfills?
-
-If you need to include [polyfills](https://remysharp.com/2010/10/08/what-is-a-polyfill)
-in your project, you must make sure those load before any other JavaScript. If you're
-using some polyfill CDN service, like [cdn.polyfill.io](https://cdn.polyfill.io/),
-just put it before the other scripts in the bottom of the page:
-
-```html
-    <script src="https://cdn.polyfill.io/v1/polyfill.min.js"></script>
-    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

-    <script src="js/plugins.js"></script>

-</body>
-```
-
-If you like to just include the polyfills yourself, you could include them in
-`js/plugins.js`. When you have a bunch of polyfills to load in, you could
-also create a `polyfills.js` file in the `js/vendor` directory. Also using
-this technique, make sure the polyfills are all loaded before any other
-Javascript.
-
-There are some misconceptions about Modernizr and polyfills. It's important
-to understand that Modernizr just handles feature checking, not polyfilling
-itself. The only thing Modernizr does regarding polyfills is that the team
