GitHub Authentication

Licensei uses Github to lookup licenses for most of the packages. The used parts of GitHub API does not require authentication, but it's easy to get rate limited, so it is recommended to configure a personal access token in your environment:

export GITHUB_TOKEN=xyz

Development

The project uses Go Modules, so the minimum Go version is 1.11.4.

When all coding and testing is done, please run the test suite:

$ make check
