+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at developer@human-connection.org. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

+
+> This Prototype tries to resolve the biggest hurdle of connecting
+> our services together. This is not possible in a sane way using
+> our current approach.
+>
+> With this Prototype we can explore using the combination of
+> GraphQL and the Neo4j Graph Database for achieving the connected
+> nature of a social graph with better development experience as we
+> do not need to connect data by our own any more through weird table
+> structures etc.
+
+>
+> #### Advantages:
+> - easer data structure
+> - better connected data
+> - easy to achieve "recommendations" based on actions (relations)
+> - more performant and better to understand API
+> - better API client that uses caching
+>
+> We still need to evaluate the drawbacks and estimate the development
+> cost of such an approach
+
+## How to get in touch
+Connect with other developers over [Discord](https://discord.gg/6ub73U3)
+
+## Quick Start
+
+### Forking the repository
+Before you start, fork the repository using the fork button above, then clone it to your local machine using `git clone https://github.com/your-username/Nitro-Backend.git`
+
+### Installation with Docker
+
+Run:
+```sh
+docker-compose up
+
+# create indices etc.
+docker-compose exec neo4j migrate
+
+# if you want seed data
+# open another terminal and run
+docker-compose exec backend yarn run db:seed
+```
+
+App is [running on port 4000](http://localhost:4000/)
+
+To wipe out your neo4j database run:
+```sh
+docker-compose down -v
+```
+
+
+### Installation without Docker
+
+Install dependencies:
+
+```bash
+yarn install
+# -or-
+npm install
+```
+
+Copy:
+```
+cp .env.template .env
+```
+Configure the file `.env` according to your needs and your local setup.
+
+Start the GraphQL service:
+
+```bash
+yarn dev
+# -or-
+npm dev
+```
+
+And on the production machine run following:
+
+```bash
+yarn start
+# -or-
+npm start
+```
+
+This will start the GraphQL service (by default on localhost:4000)
+where you can issue GraphQL requests or access GraphQL Playground in the browser:
+
+![GraphQL Playground](graphql-playground.png)
+
+## Configure
+
+Set your Neo4j connection string and credentials in `.env`.
+For example:
+
+_.env_
+
+```yaml
+NEO4J_URI=bolt://localhost:7687
+NEO4J_USERNAME=neo4j
+NEO4J_PASSWORD=letmein
+```
+
+> You need to install APOC as a plugin for the graph you create in the neo4j desktop app!
+
+Note that grand-stack-starter does not currently bundle a distribution
+of Neo4j. You can download [Neo4j Desktop](https://neo4j.com/download/)
+and run locally for development, spin up a [hosted Neo4j Sandbox instance](https://neo4j.com/download/),
+run Neo4j in one of the [many cloud options](https://neo4j.com/developer/guide-cloud-deployment/),
+[spin up Neo4j in a Docker container](https://neo4j.com/developer/docker/) or on Debian-based systems install [Neo4j from the Debian Repository](http://debian.neo4j.org/).
+Just be sure to update the Neo4j connection string and credentials accordingly in `.env`.
+
+## Mock API Results
+
+Alternatively you can just mock all responses from the api which let
+you build a frontend application without running a neo4j instance.
+
+Just set `MOCK=true` inside `.env` or pass it on application start.
+
+## Seed and Reset the Database
+
+Optionally you can seed the GraphQL service by executing mutations that
+will write sample data to the database:
+
+```bash
+yarn run db:seed
+# -or-
+npm run db:seed
+```
+
+For a reset you can use the reset script:
+
+```bash
+yarn db:reset
+# -or-
+npm run db:reset
+```
+
+## Run Tests
+
+**Beware**: We have no multiple database setup at the moment. We clean the database after each test, running the tests will wipe out all your data!
+
+Run the **_jest_** tests:
+```bash
+yarn run test
+# -or-
+npm run test
+```
+Run the **_cucumber_** features:
+```bash
+yarn run test:cucumber
+# -or-
+npm run test:cucumber
+```
+
+When some tests fail, try `yarn db:reset` and after that `yarn db:seed`. Then run the tests again
+## Todo`s
+
+- [x] add jwt authentication
+- [ ] get directives working correctly (@toLower, @auth, @role, etc.)
+- [x] check if search is working
+- [x] check if sorting is working
+- [x] check if pagination is working
+- [ ] check if upload is working (using graphql-yoga?)
+- [x] evaluate middleware
+- [ ] ignore Posts and Comments by blacklisted Users
