+# Contributing
+
+Thanks for helping to make graphql-server-core awesome!
+
+We welcome all kinds of contributions:
+
+- Bug fixes
+- Documentation improvements
+- New features
+- Refactoring & tidying
+
+
+## Getting started
+
+If you have a specific contribution in mind, be sure to check the [issues](https://github.com/graphql-python/graphql-server-core/issues) and [pull requests](https://github.com/graphql-python/graphql-server-core/pulls) in progress - someone could already be working on something similar and you can help out.
+
+
+## Project setup
+
+### Development with virtualenv (recommended)
+
+After cloning this repo, create a virtualenv:
+
+```console
+virtualenv graphql-server-core-dev
+```
+
+Activate the virtualenv and install dependencies by running:
+
+```console
+python pip install -e ".[test]"
+```
+
+If you are using Linux or MacOS, you can make use of Makefile command 
+`make dev-setup`, which is a shortcut for the above python command.
+
+### Development on Conda
+
+You must create a new env (e.g. `graphql-sc-dev`) with the following command:
+
+```sh
+conda create -n graphql-sc-dev python=3.8
+```
+
+Then activate the environment with `conda activate graphql-sc-dev`.
+
+Proceed to install all dependencies by running:
+
+```console
+pip install -e ".[dev]"
+```
+
+And you ready to start development!
+
+## Running tests
+
+After developing, the full test suite can be evaluated by running:
+
+```sh
+pytest tests --cov=graphql-server-core -vv
+```
+
+If you are using Linux or MacOS, you can make use of Makefile command 
+`make tests`, which is a shortcut for the above python command.
+
+You can also test on several python environments by using tox.
+
+### Running tox on virtualenv
+
+Install tox:
+
+```console
+pip install tox
+```
+
+Run `tox` on your virtualenv (do not forget to activate it!) 
+and that's it! 
+
+### Running tox on Conda
+
+In order to run `tox` command on conda, install
+[tox-conda](https://github.com/tox-dev/tox-conda):
+
+```sh
+conda install -c conda-forge tox-conda
+```
+
+This install tox underneath so no need to install it before.
+
+Then uncomment the `requires = tox-conda` line on `tox.ini` file.
+
+Run `tox` and you will see all the environments being created 
+and all passing tests. :rocket:
