-
-## 3.2.0.0
-
-- Assets (Sass, JS, fonts) moved from `vendor/assets` to `assets`. `bootstrap.js` now contains concatenated JS.
-- Compass generator now copies JS and fonts, and provides a better default `styles.sass`.
-- Compass, Sprockets, and Mincer asset path helpers are now provided in pure Sass: `bootstrap-compass`, `bootstrap-sprockets`, and `bootstrap-mincer`.
-Asset path helpers must be imported before `bootstrap`, more in Readme.
-- Sprockets / Mincer JS manifest has been moved to `bootstrap-sprockets.js`.
-It can be required without adding Bootstrap JS directory to load path, as it now uses relative paths.
-- Sprockets: `depend_on_asset` (`glyphicons.scss`) has been changed to `depend_on` to work around an issue with `depend_on_asset`.

-* [[SO](http://stackoverflow.com/a/9909626/241212)] Added makeFluidColumn mixin for defining fluid columns. Fluid rows must use `@extend .row-fluid`, and any column inside it can use `@include makeFluidColumn(num)`, where `num` is the number of columns. Unfortunately, there is a rather major limitation to this: margins on first-child elements must be overriden. See the attached Stack Overflow answer for more information.

-# Contributing to bootstrap-sass
-
-## Asset Changes
-
-Any changes to `bootstrap-sass` assets (scss, javascripts, fonts) should be checked against the `convert` rake task.
-For usage instructions, see the [README](/README.md).
-
-If something is broken in the converter, it's preferable to update the converter along with the asset itself.
-
-
-## Bugs
-
-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. **Does it belong here?** &mdash; is this a problem with bootstrap-sass, or
-   it an issue with [twbs/bootstrap](https://github.com/twbs/bootstrap)?
-   We only distribute a direct port and will not modify files if they're not
-   changed upstream.
-
-2. **Use the GitHub issue search** &mdash; check if the issue has already been
-   reported.
-
-3. **Isolate the problem** &mdash; ideally create a [reduced test
-   case](http://css-tricks.com/6263-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).
-
-**[File a bug report](https://github.com/twbs/bootstrap-sass/issues/)**
-
-
-## Pull requests
-
-**We will not accept pull requests that modify the SCSS beyond fixing bugs caused by *our* code!**
-
-We use a [converter script][converter-readme] to automatically convert upstream bootstrap, written in LESS, to Sass.
-
-Issues related to styles or javascript but unrelated to the conversion process should go to [twbs/bootstrap][upstream].
-
-Pull requests that fix bugs caused by our code should not modify the SCSS directly, but should patch the converter instead.
-
-Good pull requests - patches, improvements, new features - are a fantastic
-help. They should remain focused in scope and avoid containing unrelated
-commits. If your contribution involves a significant amount of work or substantial
-changes to any part of the project, please open an issue to discuss it first.
-
-Make sure to adhere to the coding conventions used throughout a project
-(indentation, accurate comments, etc.). Please update any documentation that is
-relevant to the change you're making.
-
-## Do not…
-
-Please **do not** use the issue tracker for personal support requests (use
-[Stack Overflow](http://stackoverflow.com/)).
-
-Please **do not** derail or troll issues. Keep the
-discussion on topic and respect the opinions of others.

+# Bootstrap Ruby Gem
 
-`bootstrap-sass` is a Sass-powered version of [Bootstrap](http://github.com/twbs/bootstrap), ready to drop right into your Sass powered applications.
+This is the future home of the Bootstrap v4 ruby gem for Ruby on Rails (Sprockets) and Compass.
 
-## Installation
-
-Please see the appropriate guide for your environment of choice:
-
-* [Ruby on Rails](#a-ruby-on-rails).
-* [Compass](#b-compass-without-rails) not on Rails.
-* [Bower](#c-bower).
-
-### a. Ruby on Rails
-
-`bootstrap-sass` is easy to drop into Rails with the asset pipeline.
-
-In your Gemfile you need to add the `bootstrap-sass` gem, and ensure that the `sass-rails` gem is present - it is added to new Rails applications by default.
+There has not been a release yet, but if you'd like to try out the latest development version, add this to your Gemfile:
 
 ```ruby
-gem 'bootstrap-sass', '~> 3.3.5'
-gem 'sass-rails', '>= 3.2'
-```
-
-`bundle install` and restart your server to make the files available through the pipeline.
-
-Import Bootstrap styles in `app/assets/stylesheets/application.scss`:
-
-```scss
-// "bootstrap-sprockets" must be imported before "bootstrap" and "bootstrap/variables"
-@import "bootstrap-sprockets";
-@import "bootstrap";
-```
-
-`bootstrap-sprockets` must be imported before `bootstrap` for the icon fonts to work.
-
-Make sure the file has `.scss` extension (or `.sass` for Sass syntax). If you have just generated a new Rails app,
-it may come with a `.css` file instead. If this file exists, it will be served instead of Sass, so rename it:
-
-```console
-$ mv app/assets/stylesheets/application.css app/assets/stylesheets/application.scss
-```
-
-Then, remove all the `//= require` and `//= require_tree` statements from the file. Instead, use `@import` to import Sass files.
-
-Do not use `//= require` in Sass or your other stylesheets will not be [able to access][antirequire] the Bootstrap mixins or variables.
-
-Require Bootstrap Javascripts in `app/assets/javascripts/application.js`:
-
-```js
-//= require jquery
-//= require bootstrap-sprockets
-```
-
-`bootstrap-sprockets` and `bootstrap` [should not both be included](https://github.com/twbs/bootstrap-sass/issues/829#issuecomment-75153827) in `application.js`.
-
-`bootstrap-sprockets` provides individual Bootstrap Javascript files (`alert.js` or `dropdown.js`, for example), while
-`bootstrap` provides a concatenated file containing all Bootstrap Javascripts.
-
-#### Bower with Rails
-
-When using [bootstrap-sass Bower package](#c-bower) instead of the gem in Rails, configure assets in `config/application.rb`:
-
-```ruby
-# Bower asset paths
-root.join('vendor', 'assets', 'bower_components').to_s.tap do |bower_path|
-  config.sass.load_paths << bower_path
-  config.assets.paths << bower_path
-end
-# Precompile Bootstrap fonts
-config.assets.precompile << %r(bootstrap-sass/assets/fonts/bootstrap/[\w-]+\.(?:eot|svg|ttf|woff2?)$)
-# Minimum Sass number precision required by bootstrap-sass
-::Sass::Script::Value::Number.precision = [8, ::Sass::Script::Value::Number.precision].max
-```
-
-Replace Bootstrap `@import` statements in `application.scss` with:
-
-```scss
-$icon-font-path: "bootstrap-sass/assets/fonts/bootstrap/";
-@import "bootstrap-sass/assets/stylesheets/bootstrap-sprockets";
-@import "bootstrap-sass/assets/stylesheets/bootstrap";
-```
-
-Replace Bootstrap `require` directive in `application.js` with:
-
-```js
-//= require bootstrap-sass/assets/javascripts/bootstrap-sprockets
-```
-
-#### Rails 4.x
-
-Please make sure `sprockets-rails` is at least v2.1.4.
-
-#### Rails 3.2.x
-
-bootstrap-sass is no longer compatible with Rails 3. The latest version of bootstrap-sass compatible with Rails 3.2 is v3.1.1.0.
-
-### b. Compass without Rails
-
-Install the gem:
-
-```console
-$ gem install bootstrap-sass
-```
-
-If you have an existing Compass project:
-
-1. Require `bootstrap-sass` in `config.rb`:
-
-    ```ruby
-    require 'bootstrap-sass'
-    ```
-
-2. Install Bootstrap with:
-
-    ```console
-    $ bundle exec compass install bootstrap -r bootstrap-sass
-    ```
-
-If you are creating a new Compass project, you can generate it with bootstrap-sass support:
-
-```console
-$ bundle exec compass create my-new-project -r bootstrap-sass --using bootstrap
+gem 'bootstrap', git: 'https://github.com/twbs/bootstrap-rubygem'
 ```
-
-or, alternatively, if you're not using a Gemfile for your dependencies:
-
-```console
-$ compass create my-new-project -r bootstrap-sass --using bootstrap
-```
-
-This will create a new Compass project with the following files in it:
-
-* [styles.sass](/templates/project/styles.sass) - main project Sass file, imports Bootstrap and variables.
-* [_bootstrap-variables.sass](/templates/project/_bootstrap-variables.sass) - all of Bootstrap variables, override them here.
-
-Some bootstrap-sass mixins may conflict with the Compass ones.
-If this happens, change the import order so that Compass mixins are loaded later.
-
-### c. Bower
-
-bootstrap-sass Bower package is compatible with node-sass 3.2.0+. You can install it with:
-
-```console
-$ bower install bootstrap-sass
-```
-
-Sass, JS, and all other assets are located at [assets](/assets).
-
-By default, `bower.json` main field list only the main `_bootstrap.scss` and all the static assets (fonts and JS).
-This is compatible by default with asset managers such as [wiredep](https://github.com/taptapship/wiredep).
-
-#### Node.js Mincer
-
-If you use [mincer][mincer] with node-sass, import bootstrap like so:
-
-In `application.css.ejs.scss` (NB **.css.ejs.scss**):
-
-```scss
-// Import mincer asset paths helper integration
-@import "bootstrap-mincer";
-@import "bootstrap";
-```
-
-In `application.js`:
-
-```js
-//= require bootstrap-sprockets
-```
-
-See also this [example manifest.js](/test/dummy_node_mincer/manifest.js) for mincer.
-
-
-### Configuration
-
-#### Sass
-
-By default all of Bootstrap is imported.
-
-You can also import components explicitly. To start with a full list of modules copy
-[`_bootstrap.scss`](assets/stylesheets/_bootstrap.scss) file into your assets as `_bootstrap-custom.scss`.
-Then comment out components you do not want from `_bootstrap-custom`.
-In the application Sass file, replace `@import 'bootstrap'` with:
-
-```scss
-@import 'bootstrap-custom';
-```
-
-#### Sass: Number Precision
-
-bootstrap-sass [requires](https://github.com/twbs/bootstrap-sass/issues/409) minimum [Sass number precision][sass-precision] of 8 (default is 5).
-
-Precision is set for Rails and Compass automatically.
-When using ruby Sass compiler standalone or with the Bower version you can set it with:
-
-```ruby
-::Sass::Script::Value::Number.precision = [8, ::Sass::Script::Value::Number.precision].max
-```
-
-#### Sass: Autoprefixer
-
-Bootstrap requires the use of [Autoprefixer][autoprefixer].
-[Autoprefixer][autoprefixer] adds vendor prefixes to CSS rules using values from [Can I Use](http://caniuse.com/).
-
-#### JavaScript
-
-[`assets/javascripts/bootstrap.js`](/assets/javascripts/bootstrap.js) contains all of Bootstrap JavaScript,
-concatenated in the [correct order](/assets/javascripts/bootstrap-sprockets.js).
-
-
-#### JavaScript with Sprockets or Mincer
-
-If you use Sprockets or Mincer, you can require `bootstrap-sprockets` instead to load the individual modules:
-
-```js
-// Load all Bootstrap JavaScript
-//= require bootstrap-sprockets
-```
-
-You can also load individual modules, provided you also require any dependencies.
-You can check dependencies in the [Bootstrap JS documentation][jsdocs].
-
-```js
-//= require bootstrap/scrollspy
-//= require bootstrap/modal
-//= require bootstrap/dropdown
-```
-
-#### Fonts
-
-The fonts are referenced as:
-
-```scss
-"#{$icon-font-path}#{$icon-font-name}.eot"
-```
-
-`$icon-font-path` defaults to `bootstrap/` if asset path helpers are used, and `../fonts/bootstrap/` otherwise.
-
-When using bootstrap-sass with Compass, Sprockets, or Mincer, you **must** import the relevant path helpers before Bootstrap itself, for example:
-
-```scss
-@import "bootstrap-compass";
-@import "bootstrap";
-```
-
-## Usage
-
-### Sass
-
-Import Bootstrap into a Sass file (for example, application.scss) to get all of Bootstrap's styles, mixins and variables!
-
-```scss
-@import "bootstrap";
-```
-
-You can also include optional bootstrap theme:
-
-```scss
-@import "bootstrap/theme";
-```
-
-The full list of bootstrap variables can be found [here](http://getbootstrap.com/customize/#less-variables). You can override these by simply redefining the variable before the `@import` directive, e.g.:
-
-```scss
-$navbar-default-bg: #312312;
-$light-orange: #ff8c00;
-$navbar-default-color: $light-orange;
-
-@import "bootstrap";
-```
-
-## Version
-
-Bootstrap for Sass version may differ from the upstream version in the last number, known as
-[PATCH](http://semver.org/spec/v2.0.0.html). The patch version may be ahead of the corresponding upstream minor.
-This happens when we need to release Sass-specific changes.
-
-Before v3.3.2, Bootstrap for Sass version used to reflect the upstream version, with an additional number for
-Sass-specific changes. This was changed due to Bower and npm compatibility issues.
-
-The upstream versions vs the Bootstrap for Sass versions are:
-
-| Upstream |    Sass |
-|---------:|--------:|
-|    3.3.5 |   3.3.5 |
-|    3.3.4 |   3.3.4 |
-|    3.3.2 |   3.3.3 |
-| <= 3.3.1 | 3.3.1.x |
-
-Always refer to [CHANGELOG.md](/CHANGELOG.md) when upgrading.

-## Development and Contributing
-
-If you'd like to help with the development of bootstrap-sass itself, read this section.
-
-### Upstream Converter
-
-Keeping bootstrap-sass in sync with upstream changes from Bootstrap used to be an error prone and time consuming manual process. With Bootstrap 3 we have introduced a converter that automates this.
-
-**Note: if you're just looking to *use* Bootstrap 3, see the [installation](#installation) section above.**
-
-Upstream changes to the Bootstrap project can now be pulled in using the `convert` rake task.
-
-Here's an example run that would pull down the master branch from the main [twbs/bootstrap](https://github.com/twbs/bootstrap) repo:
-
-    rake convert
-
-This will convert the latest LESS to Sass and update to the latest JS.
-To convert a specific branch or version, pass the branch name or the commit hash as the first task argument:
-
-    rake convert[e8a1df5f060bf7e6631554648e0abde150aedbe4]
-
-The latest converter script is located [here][converter] and does the following:
-
-* Converts upstream bootstrap LESS files to its matching SCSS file.
-* Copies all upstream JavaScript into `assets/javascripts/bootstrap`, a Sprockets manifest at `assets/javascripts/bootstrap-sprockets.js`, and a concatenation at `assets/javascripts/bootstrap.js`.
-* Copies all upstream font files into `assets/fonts/bootstrap`.
-* Sets `Bootstrap::BOOTSTRAP_SHA` in [version.rb][version] to the branch sha.
-
-This converter fully converts original LESS to SCSS. Conversion is automatic but requires instructions for certain transformations (see converter output).
-Please submit GitHub issues tagged with `conversion`.
