Valid go.mod file

The Go module system was introduced in Go 1.11 and is the official dependency management solution for Go.
Redistributable license

Redistributable licenses place minimal restrictions on how software can be used, modified, and redistributed.
Tagged version

Modules with tagged versions give importers more predictable builds.
Stable version

When a project reaches major version v1 it is considered stable.

experimental code

This directory contain drivers that are considered unstable or incomplete as per driver lifetime management. We encourage you to try them and give feedback via new issues or improvements via a pull request, so we can assert of their quality before promoting them as stable drivers.

You are welcome to create pull requests to add drivers here or improve the quality of drivers already here. Please make sure to abide to requests in project/contributing/.

To add a new driver, you can optionally start your work off driverskeleton/ and follow the instructions in the files.
