-### Issues bots
-
-[@twbs-lmvtfy](https://github.com/twbs-lmvtfy) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks for HTML validation errors in live examples (e.g. jsFiddles, JS Bins, Bootplys, Plunks, CodePens, etc.) posted in issue comments. If it finds any errors, it will post a follow-up comment on the issue and point out the errors. If this happens with an example you've posted, please fix the errors and post an updated live example. If you opened a bug report, please check whether the bug still occurs with your revised, valid live example. If the bug no longer occurs, it was probably due to your invalid HTML rather than something in Bootstrap and we'd appreciate it if you could close out the GitHub issue.

-[@twbs-rorschach](https://github.com/twbs-rorschach) is a Bootstrap bot that hangs out in our GitHub issue tracker and automatically checks all pull requests for a few simple common mistakes. It's possible that Rorschach might leave a comment on your pull request and then close it. If that happens, simply fix the problem(s) mentioned in the comment (there should be link(s) in the comment explaining the problem(s) in detail) and then either:
-
-* Push the revised version to your pull request's branch and post a comment on the pull request saying that you've fixed the problem(s). One of the Bootstrap Core Team members will then come along and reopen your pull request.
-* Or you can just open a new pull request for your revised version.
-
-[@twbs-savage](https://github.com/twbs-savage) is a Bootstrap bot that automatically runs cross-browser tests (via [Sauce](https://saucelabs.com) and Travis CI) on JavaScript pull requests. Savage will leave a comment on pull requests stating whether cross-browser JS tests passed or failed, with a link to the full Travis build details. If your pull request fails, check the Travis log to see which browser + OS combinations failed. Each browser test in the Travis log includes a link to a Sauce page with details about the test. On those details pages, you can watch a screencast of the test run to see exactly which unit tests failed.

+# 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 mdo@getbootstrap.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](https://www.contributor-covenant.org/), version 1.4, available at <https://www.contributor-covenant.org/version/1/4/code-of-conduct/>

-
-THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
-COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
-COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
-AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
-
-BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
-TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
-BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
-CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
-CONDITIONS.
-
-1. Definitions
-
- a. "Adaptation" means a work based upon the Work, or upon the Work and
-    other pre-existing works, such as a translation, adaptation,
-    derivative work, arrangement of music or other alterations of a
-    literary or artistic work, or phonogram or performance and includes
-    cinematographic adaptations or any other form in which the Work may be
-    recast, transformed, or adapted including in any form recognizably
-    derived from the original, except that a work that constitutes a
-    Collection will not be considered an Adaptation for the purpose of
-    this License. For the avoidance of doubt, where the Work is a musical
-    work, performance or phonogram, the synchronization of the Work in
-    timed-relation with a moving image ("synching") will be considered an
-    Adaptation for the purpose of this License.
- b. "Collection" means a collection of literary or artistic works, such as
-    encyclopedias and anthologies, or performances, phonograms or
-    broadcasts, or other works or subject matter other than works listed
-    in Section 1(f) below, which, by reason of the selection and
-    arrangement of their contents, constitute intellectual creations, in
-    which the Work is included in its entirety in unmodified form along
-    with one or more other contributions, each constituting separate and
-    independent works in themselves, which together are assembled into a
-    collective whole. A work that constitutes a Collection will not be
-    considered an Adaptation (as defined above) for the purposes of this
-    License.
- c. "Distribute" means to make available to the public the original and
-    copies of the Work or Adaptation, as appropriate, through sale or
-    other transfer of ownership.
- d. "Licensor" means the individual, individuals, entity or entities that
-    offer(s) the Work under the terms of this License.
- e. "Original Author" means, in the case of a literary or artistic work,
-    the individual, individuals, entity or entities who created the Work
-    or if no individual or entity can be identified, the publisher; and in
-    addition (i) in the case of a performance the actors, singers,
-    musicians, dancers, and other persons who act, sing, deliver, declaim,
-    play in, interpret or otherwise perform literary or artistic works or
-    expressions of folklore; (ii) in the case of a phonogram the producer
-    being the person or legal entity who first fixes the sounds of a
-    performance or other sounds; and, (iii) in the case of broadcasts, the
-    organization that transmits the broadcast.
- f. "Work" means the literary and/or artistic work offered under the terms
-    of this License including without limitation any production in the
-    literary, scientific and artistic domain, whatever may be the mode or
-    form of its expression including digital form, such as a book,
-    pamphlet and other writing; a lecture, address, sermon or other work
-    of the same nature; a dramatic or dramatico-musical work; a
-    choreographic work or entertainment in dumb show; a musical
-    composition with or without words; a cinematographic work to which are
-    assimilated works expressed by a process analogous to cinematography;
-    a work of drawing, painting, architecture, sculpture, engraving or
-    lithography; a photographic work to which are assimilated works
-    expressed by a process analogous to photography; a work of applied
-    art; an illustration, map, plan, sketch or three-dimensional work
-    relative to geography, topography, architecture or science; a
-    performance; a broadcast; a phonogram; a compilation of data to the
-    extent it is protected as a copyrightable work; or a work performed by
-    a variety or circus performer to the extent it is not otherwise
-    considered a literary or artistic work.
- g. "You" means an individual or entity exercising rights under this
-    License who has not previously violated the terms of this License with
-    respect to the Work, or who has received express permission from the
-    Licensor to exercise rights under this License despite a previous
-    violation.
- h. "Publicly Perform" means to perform public recitations of the Work and
-    to communicate to the public those public recitations, by any means or
-    process, including by wire or wireless means or public digital
-    performances; to make available to the public Works in such a way that
-    members of the public may access these Works from a place and at a
-    place individually chosen by them; to perform the Work to the public
-    by any means or process and the communication to the public of the
-    performances of the Work, including by public digital performance; to
-    broadcast and rebroadcast the Work by any means including signs,
-    sounds or images.
- i. "Reproduce" means to make copies of the Work by any means including
-    without limitation by sound or visual recordings and the right of
-    fixation and reproducing fixations of the Work, including storage of a
-    protected performance or phonogram in digital form or other electronic
-    medium.
-
-2. Fair Dealing Rights. Nothing in this License is intended to reduce,
-limit, or restrict any uses free from copyright or rights arising from
-limitations or exceptions that are provided for in connection with the
-copyright protection under copyright law or other applicable laws.
-
-3. License Grant. Subject to the terms and conditions of this License,
-Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
-perpetual (for the duration of the applicable copyright) license to
-exercise the rights in the Work as stated below:
-
- a. to Reproduce the Work, to incorporate the Work into one or more
-    Collections, and to Reproduce the Work as incorporated in the
-    Collections;
- b. to create and Reproduce Adaptations provided that any such Adaptation,
-    including any translation in any medium, takes reasonable steps to
-    clearly label, demarcate or otherwise identify that changes were made
-    to the original Work. For example, a translation could be marked "The
-    original work was translated from English to Spanish," or a
-    modification could indicate "The original work has been modified.";
- c. to Distribute and Publicly Perform the Work including as incorporated
-    in Collections; and,
- d. to Distribute and Publicly Perform Adaptations.
- e. For the avoidance of doubt:
-
-     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme cannot be waived, the Licensor
-        reserves the exclusive right to collect such royalties for any
-        exercise by You of the rights granted under this License;
-    ii. Waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme can be waived, the Licensor waives the
-        exclusive right to collect such royalties for any exercise by You
-        of the rights granted under this License; and,
-   iii. Voluntary License Schemes. The Licensor waives the right to
-        collect royalties, whether individually or, in the event that the
-        Licensor is a member of a collecting society that administers
-        voluntary licensing schemes, via that society, from any exercise
-        by You of the rights granted under this License.
-
-The above rights may be exercised in all media and formats whether now
-known or hereafter devised. The above rights include the right to make
-such modifications as are technically necessary to exercise the rights in
-other media and formats. Subject to Section 8(f), all rights not expressly
-granted by Licensor are hereby reserved.
-
-4. Restrictions. The license granted in Section 3 above is expressly made
-subject to and limited by the following restrictions:
-
- a. You may Distribute or Publicly Perform the Work only under the terms
-    of this License. You must include a copy of, or the Uniform Resource
-    Identifier (URI) for, this License with every copy of the Work You
-    Distribute or Publicly Perform. You may not offer or impose any terms
-    on the Work that restrict the terms of this License or the ability of
-    the recipient of the Work to exercise the rights granted to that
-    recipient under the terms of the License. You may not sublicense the
-    Work. You must keep intact all notices that refer to this License and
-    to the disclaimer of warranties with every copy of the Work You
-    Distribute or Publicly Perform. When You Distribute or Publicly
-    Perform the Work, You may not impose any effective technological
-    measures on the Work that restrict the ability of a recipient of the
-    Work from You to exercise the rights granted to that recipient under
-    the terms of the License. This Section 4(a) applies to the Work as
-    incorporated in a Collection, but this does not require the Collection
-    apart from the Work itself to be made subject to the terms of this
-    License. If You create a Collection, upon notice from any Licensor You
-    must, to the extent practicable, remove from the Collection any credit
-    as required by Section 4(b), as requested. If You create an
-    Adaptation, upon notice from any Licensor You must, to the extent
-    practicable, remove from the Adaptation any credit as required by
-    Section 4(b), as requested.
- b. If You Distribute, or Publicly Perform the Work or any Adaptations or
-    Collections, You must, unless a request has been made pursuant to
-    Section 4(a), keep intact all copyright notices for the Work and
-    provide, reasonable to the medium or means You are utilizing: (i) the
-    name of the Original Author (or pseudonym, if applicable) if supplied,
-    and/or if the Original Author and/or Licensor designate another party
-    or parties (e.g., a sponsor institute, publishing entity, journal) for
-    attribution ("Attribution Parties") in Licensor's copyright notice,
-    terms of service or by other reasonable means, the name of such party
-    or parties; (ii) the title of the Work if supplied; (iii) to the
-    extent reasonably practicable, the URI, if any, that Licensor
-    specifies to be associated with the Work, unless such URI does not
-    refer to the copyright notice or licensing information for the Work;
-    and (iv) , consistent with Section 3(b), in the case of an Adaptation,
-    a credit identifying the use of the Work in the Adaptation (e.g.,
-    "French translation of the Work by Original Author," or "Screenplay
-    based on original Work by Original Author"). The credit required by
-    this Section 4 (b) may be implemented in any reasonable manner;
-    provided, however, that in the case of a Adaptation or Collection, at
-    a minimum such credit will appear, if a credit for all contributing
-    authors of the Adaptation or Collection appears, then as part of these
-    credits and in a manner at least as prominent as the credits for the
-    other contributing authors. For the avoidance of doubt, You may only
-    use the credit required by this Section for the purpose of attribution
-    in the manner set out above and, by exercising Your rights under this
-    License, You may not implicitly or explicitly assert or imply any
-    connection with, sponsorship or endorsement by the Original Author,
-    Licensor and/or Attribution Parties, as appropriate, of You or Your
-    use of the Work, without the separate, express prior written
-    permission of the Original Author, Licensor and/or Attribution
-    Parties.
- c. Except as otherwise agreed in writing by the Licensor or as may be
-    otherwise permitted by applicable law, if You Reproduce, Distribute or
-    Publicly Perform the Work either by itself or as part of any
-    Adaptations or Collections, You must not distort, mutilate, modify or
-    take other derogatory action in relation to the Work which would be
-    prejudicial to the Original Author's honor or reputation. Licensor
-    agrees that in those jurisdictions (e.g. Japan), in which any exercise
-    of the right granted in Section 3(b) of this License (the right to
-    make Adaptations) would be deemed to be a distortion, mutilation,
-    modification or other derogatory action prejudicial to the Original
-    Author's honor and reputation, the Licensor will waive or not assert,
-    as appropriate, this Section, to the fullest extent permitted by the
-    applicable national law, to enable You to reasonably exercise Your
-    right under Section 3(b) of this License (right to make Adaptations)
-    but not otherwise.
-
-5. Representations, Warranties and Disclaimer
-
-UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
-OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
-KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
-INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
-FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
-LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
-WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
-OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
-
-6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
-LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
-ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
-ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
-BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. Termination
-
- a. This License and the rights granted hereunder will terminate
-    automatically upon any breach by You of the terms of this License.
-    Individuals or entities who have received Adaptations or Collections
-    from You under this License, however, will not have their licenses
-    terminated provided such individuals or entities remain in full
-    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
-    survive any termination of this License.
- b. Subject to the above terms and conditions, the license granted here is
-    perpetual (for the duration of the applicable copyright in the Work).
-    Notwithstanding the above, Licensor reserves the right to release the
-    Work under different license terms or to stop distributing the Work at
-    any time; provided, however that any such election will not serve to
-    withdraw this License (or any other license that has been, or is
-    required to be, granted under the terms of this License), and this
-    License will continue in full force and effect unless terminated as
-    stated above.
-
-8. Miscellaneous
-
- a. Each time You Distribute or Publicly Perform the Work or a Collection,
-    the Licensor offers to the recipient a license to the Work on the same
-    terms and conditions as the license granted to You under this License.
- b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
-    offers to the recipient a license to the original Work on the same
-    terms and conditions as the license granted to You under this License.
- c. If any provision of this License is invalid or unenforceable under
-    applicable law, it shall not affect the validity or enforceability of
-    the remainder of the terms of this License, and without further action
-    by the parties to this agreement, such provision shall be reformed to
-    the minimum extent necessary to make such provision valid and
-    enforceable.
- d. No term or provision of this License shall be deemed waived and no
-    breach consented to unless such waiver or consent shall be in writing
-    and signed by the party to be charged with such waiver or consent.
- e. This License constitutes the entire agreement between the parties with
-    respect to the Work licensed here. There are no understandings,
-    agreements or representations with respect to the Work not specified
-    here. Licensor shall not be bound by any additional provisions that
-    may appear in any communication from You. This License may not be
-    modified without the mutual written agreement of the Licensor and You.
- f. The rights granted under, and the subject matter referenced, in this
-    License were drafted utilizing the terminology of the Berne Convention
-    for the Protection of Literary and Artistic Works (as amended on
-    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
-    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
-    and the Universal Copyright Convention (as revised on July 24, 1971).
-    These rights and subject matter take effect in the relevant
-    jurisdiction in which the License terms are sought to be enforced
-    according to the corresponding provisions of the implementation of
-    those treaty provisions in the applicable national law. If the
-    standard suite of rights granted under applicable copyright law
-    includes additional rights not granted under this License, such
-    additional rights are deemed to be included in the License; this
-    License is not intended to restrict the license of any rights under
-    applicable law.

-redirect_from: "/about/"
----
-
-Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.
-
-Bootstrap was created at Twitter in mid-2010 by [@mdo](https://twitter.com/mdo) and [@fat](https://twitter.com/fat). Prior to being an open-sourced framework, Bootstrap was known as _Twitter Blueprint_. A few months into development, Twitter held its [first Hack Week](https://blog.twitter.com/2010/hack-week) and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.
-
-Originally [released](https://blog.twitter.com/2011/bootstrap-twitter) on [<time datetime="2011-08-19 11:25">Friday, August 19, 2011</time>](https://twitter.com/mdo/statuses/104620039650557952), we've since had over [twenty releases](https://github.com/twbs/bootstrap/releases), including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.
