# Contributing Spring Cloud is released under the non-restrictive Apache 2.0 license, and follows a very standard Github development process, using Github tracker for issues and merging pull requests into master. If you want to contribute even something trivial please do not hesitate, but follow the guidelines below. ## Code of Conduct This project adheres to the Contributor Covenant [code of conduct](https://github.com/spring-cloud/spring-cloud-build/blob/master/docs/src/main/asciidoc/code-of-conduct.adoc). By participating, you are expected to uphold this code. Please report unacceptable behavior to spring-code-of-conduct@pivotal.io. ## Code Conventions and Housekeeping None of these is essential for a pull request, but they will all help. They can also be added after the original pull request but before a merge. * We use the [Spring JavaFormat](https://github.com/spring-io/spring-javaformat/) project to apply code formatting conventions. Format de code running `./mvnw io.spring.javaformat:spring-javaformat-maven-plugin:apply` * Make sure all new `.java` files to have a simple Javadoc class comment with at least an `@author` tag identifying you, and preferably at least a paragraph on what the class is for. * Add the ASF license header comment to all new `.java` files (copy from existing files in the project) * Add yourself as an `@author` to the .java files that you modify substantially (more than cosmetic changes). * Add some Javadocs and, if you change the namespace, some XSD doc elements. * A few unit tests would help a lot as well -- someone has to do it. * If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project). * When writing a commit message please follow [these conventions](https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html), if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit message (where XXXX is the issue number).
