To start using cool-helpers you can:

• Download the last release
• Install with bower: bower install cool-helpers --save-dev

###Build the project

If you want to build the project locally, you have to run the Grunt task grunt build. This task will concat and minify the sources and create the README.md. Before all this, you do not forget to run npm install and bower install.

####Contribute

If you want to keep growing cool-helpers up, send us a pull request with your new helpers. You must follow this steps:

• Add the helper to its proper category file inside src/helpers directory. If you want to create a new category, create the new js file and add it at src/helpers/start.js.
• Do your commit message following the commit conventions. The changelog will be created using the commited messages.
• Document the helper. No pull request will be accepted without proper documentation. Documentation directory is doc. If you need to create a new documentation section, remember to add it at Gruntfile, inside readme_generator.readme.order. Also, you have to write low-level documentation using JSDoc.
• Remember to build the project before doing the pull-request.
