+
+Thank you for contributing to the landlab tutorials! We appreciate
+your help as this is largely as volunteer effort! :heart: :heart: :heart:
+
+# How to contribute
+
+## Reporting Bugs
+
+Before creating a bug report, please do at least a cursory check that the
+bug has not already been reported. If it has, add a comment to the existing
+issue instead of opening a new one.
+
+### Submitting a Bug Report
+
+Bugs are tracked as
+[GitHub issues](https://guides.github.com/features/issues/). After you've
+determined you've found a new bug, please open a
+[new issue](https://github.com/landlab/tutorials/issues).
+
+Explain the problem and include additional details to help maintainers
+reproduce the problem. Here are some items that will make it easier
+to track down the source of the problem.
+
+*  **Use a clear and descriptive title** for the issue that identifies the
+   problem.
+*  **Describe the exact steps that reproduce the problem**.
+*  **If possible, provide an example that demonstrates the step** as,
+   for example, a bash script along with input files.
+*  **Describe the behavior you are seeing after these steps**.
+*  **Describe the behavior you expect to see after these steps**.
+
+Additionally, the answers to the following questions about your run
+environment will be helpful.
+
+*  **Which version of landlab are you using?** This could be a specific
+   git sha or a release number.
+*  **What is he name and version of you OS?**
+*  **What compiler are you using?**
+*  **How did you build landlab (if using the development version)?**
+
+
+## Submitting Changes
+
+:tada: Whoa! This is great! We love it when folks contibute code! :tada:
+
+Changes to landlab tutorials should be submitted as 
+[pull requests](http://help.github.com/pull-requests/)).
+
+*  Create a GitHub issue that describes what you propose to do.
+*  Create a topic branch that contains your changes.
+*  Open a new [GitHub pull request](https://github.com/landlab/tutorials/pull/new/master).
+*  Ensure the PR description clearly describes the problem and solution.
+   Include the relevant issue number.
+
+## Styleguides
+
+Use the [PEP8 style guide](https://www.python.org/dev/peps/pep-0008/).
+You may want to use tools like
+[Prospector](http://prospector.landscape.io/en/master/) to help out
+with this.
+
+### Git Commit Messages
+
+* Use the present tense ("Add feature" not "Added feature")
+* Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
+* Limit the first line to 72 characters or less
+* Reference issues and pull requests liberally
+* Consider starting the commit message with an applicable emoji:
+    * :art: `:art:` when improving the format/structure of the code
+    * :racehorse: `:racehorse:` when improving performance
+    * :non-potable_water: `:non-potable_water:` when plugging memory leaks

+
+## Adding new tutorials
+
+If you would like to create a new tutorial that we have just a few
+conventions that we would like you to follow.
+
+* Create a new folder that will hold your tutorial notebook
+  and data used by your tutorial.
+* Start with the blank tutorial template provided in this repository.
+* Notice that your first cell of code should import `print_function`
+  from `__future__`.  Your tutorial will need to be compatible with
+  both Python 2.7 and 3.4+.
+* If you will be plotting anything, be sure to use include ipython
+  magic command in the first cell to indicate how plots should
+  be rendered.
+* Your tutorial must be able to run without error for the **most
+  recent landlab release**.
+
+Thanks! :heart: :heart: :heart:

 Most of these Landlab tutorials can either be read as text files or run as interactive IPython notebooks (recommended!).
