QuickFIX/n is an open source project and we welcome your contributions to the project on github.
Start by forking the repository on github, and when you are done with your changes, issue a pull request. Information on code generation, how to build the project, tests, etc. can be found in README.md at the top level of the project.
Every Pull request should have an accompanying unit test to ensure fast acceptance of your contributions. We will run your test in addition to reviewing your changes. See the UnitTests directory for examples of existing unit tests.
