vendor/github.com/mssola/user_agent/CONTRIBUTING.md

+# Contributing to user_agent
+
+## Check that your changes do not break anything
+
+You can safely run the `ci` target locally:
+
+```
+$ make ci
+```
+
+This will run all the make targets that will also be run on the CI, which are
+described below.
+
+### Running tests
+
+Call the `test` make target:
+
+```bash
+$ make test
+```
+
+### Checking the style
+
+This project uses some standard tools in order to check the Go style. You can
+run them by calling the `validate-go` make target:
+
+```bash
+$ make validate-go
+```
+
+This target is included inside of the `validate` one.
+
+### Git validation
+
+In order to ensure that the git log is as maintainable as possible, the
+[git-validation](https://github.com/vbatts/git-validation) tool is used. You can
+install this tool by running:
+
+```bash
+$ go get -u github.com/vbatts/git-validation
+```
+
+If you already have this tool installed, then simply perform:
+
+```bash
+$ make git-validation
+```
+
+This target is included inside of the `validate` one.
+
+## Issue reporting
+
+I'm using [Github](https://github.com/mssola/user_agent) in order to host the
+code. Thus, in order to report issues you can do it on its [issue
+tracker](https://github.com/mssola/user_agent/issues). A couple of notes on
+reports:
+
+- Check that the issue has not already been reported or fixed in `master`.
+- Try to be concise and precise in your description of the problem.
+- Provide a step by step guide on how to reproduce this problem.
+- Provide the version you are using (the commit SHA, if possible).
+
+## Pull requests
+
+- Write a [good commit message](https://chris.beams.io/posts/git-commit/).
+- Make sure that tests are passing on your local machine (it will also be
+checked by the CI system whenever you submit the pull request).
+- Update the [changelog](./CHANGELOG.md).
+- Try to use the same coding conventions as used in this project.
+- Open a pull request with *only* one subject and a clear title and
+description. Refrain from submitting pull requests with tons of different
+unrelated commits.
