Within the download you'll find the following directories and files, logically grouping common assets and providing both compiled and minified variations. You'll see something like this:

We provide compiled CSS and JS (
bootstrap.*), as well as compiled and minified CSS and JS (

Previous releases and their documentation are also available for download.
Bootstrap uses Grunt with convenient methods for working with the framework. It's how we compile our code, run tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands.
From the command line:
npm install -g grunt-cli.
- Navigate to the root
/bootstrapdirectory, then run
npm install. npm will look at package.json and automatically install the necessary local dependencies listed there.
When completed, you'll be able to run the various Grunt commands provided from the command line.
npm? Don't have node installed? That's a-okay. npm stands for node packaged modules and is a way to manage development dependencies through node.js. Download and install node.js before proceeding.
This is a convenience method for watching just Less files and automatically building them whenever you save.
Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun

For transparency into our release cycle and in striving to maintain backward compatibility, Bootstrap is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we'll adhere to these rules whenever possible.
Releases will be numbered with the following format:
And constructed with the following guidelines:
- Breaking backward compatibility bumps the major while resetting minor and patch
- New additions without breaking backward compatibility bumps the minor while resetting the patch
- Bug fixes and misc changes bumps only the patch
