# Contributing code
Moto has a [Code of Conduct](https://github.com/spulec/moto/blob/master/CODE_OF_CONDUCT.md), you can expect to be treated with respect at all times when interacting with this project.
## Running the tests locally
Moto has a [Makefile](./Makefile) which has some helpful commands for getting set up.
You should be able to run `make init` to install the dependencies and then `make test` to run the tests.
*NB. On first run, some tests might take a while to execute, especially the Lambda ones, because they may need to download a Docker image before they can execute.*
## Linting
Run `make lint` or `black --check moto tests` to verify whether your code confirms to the guidelines.
## Getting to grips with the codebase
Moto maintains a list of [good first issues](https://github.com/spulec/moto/contribute) which you may want to look at before
implementing a whole new endpoint.
## Missing features
Moto is easier to contribute to than you probably think. There's [a list of which endpoints have been implemented](https://github.com/spulec/moto/blob/master/IMPLEMENTATION_COVERAGE.md) and we invite you to add new endpoints to existing services or to add new services.
How to teach Moto to support a new AWS endpoint:
* Search for an existing [issue](https://github.com/spulec/moto/issues) that matches what you want to achieve.
* If one doesn't already exist, create a new issue describing what's missing. This is where we'll all talk about the new addition and help you get it done.
* Create a [pull request](https://help.github.com/articles/using-pull-requests/) and mention the issue # in the PR description.
* Try to add a failing test case. For example, if you're trying to implement `boto3.client('acm').import_certificate()` you'll want to add a new method called `def test_import_certificate` to `tests/test_acm/test_acm.py`.
* If you can also implement the code that gets that test passing that's great. If not, just ask the community for a hand and somebody will assist you.
## Maintainers
### Releasing a new version of Moto
You'll need a PyPi account and a DockerHub account to release Moto. After we release a new PyPi package we build and push the [motoserver/moto](https://hub.docker.com/r/motoserver/moto/) Docker image.
* First, `scripts/bump_version` modifies the version and opens a PR
* Then, merge the new pull request
* Finally, generate and ship the new artifacts with `make publish`
