 You must provide `TAG` (git tag) and `PATH` to artifacts you want to upload. You can specify a file or a directory. If you provide a directory, all files in that directory uploaded.
 
-`ghr` assumes that you are in the GitHub repository root when executed. This is because normally the artifacts you want to upload to a GitHub Release page is in that repository or generated there. With this assumption, `ghr` *implicitly* reads repository URL from `.git/config` file. But You can change this kind of information via option, see [Options](#options) section.

+### GitHub API Token
 
 To use `ghr`, you need to get a GitHub token with an account which has enough permissions to to create releases. To get token, first, visit GitHub account settings page, then go to Applications for the user. Here you can create a token in the Personal access tokens section. For a private repository you need `repo` scope and for a public repository you need `public_repo` scope.
