+# Contributing to UNCode
+We love your input! We want to make contributing to this project as easy and 
+transparent as possible, whether it's:
+
+- Reporting a bug.
+- Discussing the current state of the code.
+- Submitting a fix.
+- Proposing new features
+
+## Our Development Process
+
+We use github to host code, to track issues and feature requests, as well 
+as accept pull requests.
+
+## Your First Contribution
+
+Unsure where to begin contributing to UNCode? You can start by looking through these beginner issues:
+**Good first issue** - issues which should only require a few lines of code and a not big understanding of UNCode.
+
+Working on your first Pull Request? You can learn how from this *free* series, 
+[How to Contribute to an Open Source Project on GitHub][contribute_github_url].
+
+## Pull Requests
+
+Pull requests are the best way to propose changes to the codebase 
+(we use [Github Flow][github_flow_url]. 
+
+We actively welcome your pull requests.
+
+1. Fork the repo (in case not an admin) and create your branch from `master`.
+2. If you've added code that should be tested, add tests.
+3. If you've changed APIs, update the documentation.
+4. Ensure the test suite passes.
+5. Be sure you have followed the code style for the project.
+6. If you haven't already, complete the Contributor License Agreement ("CLA"). Note the code of conduct.
+7. Create the pull request to `master` branch.
+
+### Code review
+
+UNCode team will check your pull request and one of us will be assigned to review it and
+leave feedback. Make to reply the given feedback ASAP.
+
+## Contributor License Agreement ("CLA")
+In order to accept your pull request, you will need to sign the Contributor License Agreement.
+Once the PR is created, you will be told whether or not you need to sign it and how to do it.
+
+## Issues
+We use GitHub issues to track public bugs or Feature Requests. Please ensure your description is
+clear and has sufficient instructions to be able to reproduce the issue.
+
+## License
+In short, when you submit code changes, your submissions are understood to be under the 
+same [GNU][license_url] that covers the project. 
+Feel free to contact the maintainers if that's a concern.
+
+## Community
+
+Chat with us on [Gitter][gitter_url]. 
+We will reply for sure on weekdays at GMT-5 time.

-Build dependencies:
+This is the repository for the C/C++ backend for [Online Python Tutor][python_tutor_repo_url]. We have forked this
+ repository to add some necessary modifications for our purposes, and correctly provide the python tutor service.
+
+The code of this repository is built using Docker stored in docker hub: [unjudge/opt-cpp-backend][unjudge/opt-cpp-backend],
+ which at the same time is used by a linux service called *cokapi*, see how we deploy this service [cokapi service][cokapi_url],
+ also see how Python tutor uses this deployed service in <https://github.com/JuezUN/OnlinePythonTutor/tree/master/v4-cokapi>.
+ The cokapi service is currently deployed in the port `4000`.
