+## Contributing
+
+Contributions and feedback are always welcome. The expected procedure is the following:
+
+### Bugs, Features and Feedback 
+
+* Please, create github issues for **feature-requests**, **bug reports**.
+* Feel free to open issues for **questions and problems you have**, even if they are not bugs
+  or feature requests.
+* You may even open an issue just to say you like the project.
+* For small changes, such as **typo and formatting corrections**, you can immediately
+  create a pull-request. You can use the github web-interface, but keep in mind that most of the documentation
+  is created with Thought, so you should change the template in the `.thought` directory or change the default 
+  templates in [the thought project](https://github.com/nknapp/thought/tree/master/handlebars).
+* If you have an idea for a **new feature** that you would like to implement, please **open an issue** first and ask
+  for feedback. Maybe someone else has a similar problem and different ideas.
+* If you encounter a bug you can submit a **pull-request for a failing unit test**, you should then also open an issue
+  for the bug.
+* Before making a pull-request, make sure that you commit corresponds to the coding-style. You can do this by 
+  running `npm test`.
+
+**People submitting relevant contributions will be granted commit access to the repository.**
+
+
+### Coding style
+
+[![standard][standard-image]][standard-url]
+
+This repository uses [`standard`][standard-url] to maintain code style and consistency,
+and to avoid style arguments. You can run `npm run format` to apply the coding-style, but
+you may need to fix some things manually. Make sure to use the latest version of `standard`.
+
+
+### Installing & Testing
+
+You can fork and clone the repo from github. Run 
+
+* Run `npm install` to install all the dependencies needed to build and run the project.
+* Run `npm test` to run unit tests and validate the `standard` coding-style.
+
+It is intentional to don't have `standard`, `thought`, `istanbul` and `coveralls` in the devDependencies. 
+`standard` is a rather large package which you would not want to have copied into the `node_modules`-folder
+of each of your projects. 
+
+Instead, the `pretest`- and `preformat`-scripts ensure that `standard` and `thought` are installed globally.
+If you are not allowed to install packages globally, please raise an issue, so that we can try to find a solution.
+
+
+### About this text
+
+This text is part of the [Thought](https://github.com/nknapp/thought)-project. If you have any suggestions or wishes
+to change the text, please raise an issue there for discussion.
