# Contribution Guide
+## Contributors

+Pull requests, issues and comments are welcomed. For pull requests:

+
+See the existing issues for things to start contributing.
+
+For bigger changes, make sure you start a discussion first by creating an issue and explaining the intended change.
+
+JFrog requires contributors to sign a Contributor License Agreement, known as a CLA. This serves as a record stating that the contributor is entitled to contribute the code/documentation/translation to the project and is willing to have it used in distributions and derivative works (or is willing to transfer ownership).

## Building
Simply run `make install` - this will compile the provider and install it to `~/.terraform.d`. When running this, it will take the current tag and bump it 1 patch version. It does not actually create a new tag (that will be `make release`). If you wish to use the locally installed provider, make sure your TF script refers to the new version number.
