+# Contributing to this project
+
+Please take a moment to review this document in order to make the contribution
+process easy and effective for everyone involved.
+
+Following these guidelines helps to communicate that you respect the time of
+the developers managing and developing this open source project. In return,
+they should reciprocate that respect in addressing your issue or assessing
+patches and features.
+
+
+## Using the issue tracker
+
+The issue tracker is the preferred channel for [bug reports](#bugs),
+[features requests](#features) and [submitting pull
+requests](#pull-requests), but please respect the following restrictions:
+
+* 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.
+
+
+
+## Bug reports
+
+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. **Use the GitHub issue search** — check if the issue has already been
+ reported.
+
+2. **Check if the issue has been fixed** — try to reproduce it using the
+ latest `master` or development branch in the repository.
+
+3. **Isolate the problem** — ideally create a [reduced test
+ case](http://css-tricks.com/6263-reduced-test-cases/) and a live example (you can use something like [jsfiddle](http://jsfiddle.net/) or [jsbin](http://jsbin.com/)) .
+
+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.
+>
+> `` - 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).
+
+
+
+## Feature requests
+
+Feature requests are welcome. But take a moment to find out whether your idea
+fits with the scope and aims of the project. It's up to *you* to make a strong
+case to convince the project's developers of the merits of this feature. Please
+provide as much detail and context as possible.
+
+**Please, use the GitHub issue search** to check if the feature has already been requested.
+
+
+
+## Pull requests
+
+Good pull requests - patches, improvements, new features - are a fantastic
+help. They should remain focused in scope and avoid containing unrelated
+commits.
+
+**Please ask first** before embarking on any significant pull request (e.g.
+implementing features, refactoring code, porting to a different language),
+otherwise you risk spending a lot of time working on something that the
+project's developers might not want to merge into the project.
+
+Code must follow, mostly, these [coding conventions](http://javascript.crockford.com/code.html) .
+
+Adhering to the following this process is the best way to get your work
+included in the project:
+
+1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork,
+ and configure the remotes:
+
+ ```bash
+ # Clone your fork of the repo into the current directory
+ git clone https://github.com//gridster.js
+ # Navigate to the newly cloned directory
+ cd gridster.js
+ # Assign the original repo to a remote called "upstream"
+ git remote add upstream https://github.com/ducksboard/gridster.js
+ ```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+ ```bash
+ git checkout master
+ git pull upstream master
+ ```
+
+3. Create a new topic branch (off the main project development branch) to
+ contain your feature, change, or fix:
+
+ ```bash
+ git checkout -b
+ ```
+
+4. Commit your changes in logical chunks. Please adhere to these [git commit
+ message guidelines](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y)
+ or your code is unlikely be merged into the main project. Use Git's
+ [interactive rebase](https://help.github.com/articles/interactive-rebase)
+ feature to tidy up your commits before making them public.
+
+5. Merge or rebase the upstream development branch into your topic branch:
+
+ ```bash
+ git pull --rebase upstream master
+ ```
+
+6. Push your topic branch up to your fork:
+
+ ```bash
+ git push origin
+ ```
+
+7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/)
+ with a clear title and description.
+
+**IMPORTANT**: By submitting a patch, you agree to allow the project owner to
+license your work under the same license as that used by the project.

+Gridster.js
+===========
+
+[](https://bitdeli.com/free "Bitdeli Badge")
+
+Gridster is a jQuery plugin that makes building intuitive draggable
+layouts from elements spanning multiple columns. You can even
+dynamically add and remove elements from the grid.
+
+More at [http://gridster.net/](http://gridster.net/).
+
+[Releases](https://github.com/ducksboard/gridster.js/releases)
+
+[CHANGELOG](https://github.com/ducksboard/gridster.js/blob/master/CHANGELOG.md)
+
+Gridster is maintained by Ducksboard occasionally but not actively.
+@dustmoo and @pushmatrix have also write permissions as Gridster maintainers
+they are. Thank you guys!
+
+## Forks
+
+Mr @dustmoo (maintainer of Gridster) has his own fork of gridster.js
+with some new interesting features like widget-swapping and static widgets.
+
+Can be found here: [dustmoo/gridster.js](https://github.com/dustmoo/gridster.js)
+
+@dustmoo is working in his spare time to merge all these changes into
+ducksboard/gridster.js
+
+If anyone would like to help @dustmoo improve his fork and reconcile
+it with the main library he would be happy for the help.
