+##Contributing##
+
+Where to start
+
+There are many different ways to contribute to **rest-api-node-typescript**'s development, just find the one that best fits with your skills. Examples of contributions we would love to receive include:
+
+   - Code patches [pull request](https://help.github.com/articles/creating-a-pull-request/)
+   - Documentation improvements
+   - Translations(yet to come)
+   - Bug reports
+   - Patch reviews
+   - UI enhancements
+
+When contributing to this repository, please first discuss the change you wish to make via issue or any other method with the owners of this repository before making a change.
+
+Please note we have a code of conduct, please follow it in all your interactions with the project.
+
+##Reporting Issues##
+
+Have you identified a reproducible problem in this repo? Have a feature request? We want to hear about it! Here's how you can make reporting your issue as effective as possible.
+
+##Look For an Existing Issue##
+Before you create a new issue, please do a search in open issues to see if the issue or feature request has already been filed.
+
+Be sure to scan through the most popular feature requests.
+
+If you find your issue already exists, make relevant comments and add your reaction. Use a reaction in place of a "+1" comment:
+
+👍 - upvote
+
+👎 - downvote
+
+If you cannot find an existing issue that describes your bug or feature, create a new issue using the guidelines below.
+
+##Writing Good Bug Reports and Feature Requests##
+File a single issue per problem and feature request. Do not enumerate multiple bugs or feature requests in the same issue.
+
+Do not add your issue as a comment to an existing issue unless it's for the identical input. Many issues look similar but have different causes.
+
+The more information you can provide, the more likely someone will be successful in reproducing the issue and finding a fix.
+
+Please include the following with each issue:
+
+- OS
+- The version of Node.js, npm / yarn
+- Reproducible steps (1... 2... 3...) that cause the issue
+- What you expected to see, versus what you actually saw
+- Images, animations, or a link to a video showing the issue occurring
+- A code snippet that demonstrates the issue or a link to a code repository the developers can easily pull down to recreate the issue locally
+    - **Note**: Because the developers need to copy and paste the code snippet, including a code snippet as a media file (i.e. .gif) is not sufficient.
+- Errors from the Dev Tools Console (open from the menu: Help > Toggle Developer Tools)
+
+##Thank You!##
+Your contributions to open source, large or small, make great projects like this possible. Thank you for taking the time to contribute.
