First, ensure that you have the latest [Node.js](http://nodejs.org/) and [npm](http://npmjs.org/) installed.
Test that Grunt's CLI is installed by running `grunt --version`. If the command isn't found, run `npm install -g grunt-cli`. For more information about installing Grunt, see the [getting started with Grunt guide](http://gruntjs.com/getting-started).
1. Fork and clone the repo.
2. Run `npm install` to install all build dependencies (including Grunt).
3. Run `grunt` to grunt this project.
Assuming that you don't see any red, you're ready to go. Just be sure to run `grunt` after making any changes, to ensure that nothing is broken.
## Submitting pull requests
1. Create a new branch, please don't work in your `master` branch directly.
2. Add failing tests for the change you want to make. [See the test suite's README for instructions on how to do this.](https://github.com/twbs/bootlint/blob/master/test/README.md) Run `grunt` to see the tests fail.
6. If you upgraded or added any dependencies in `package.json`, run `grunt update-shrinkwrap` and (in a separate commit) commit the updated `/test-infra/npm-shrinkwrap.json` file. This updates the package versions used by the Travis CI build.
