-### Composer GitHub OAuth

-If you have a number of workflows which set up multiple tools or have many composer dependencies, you might hit the GitHub's rate limit for composer. Also, if you specify only the major version or the version in `major.minor` format, you can hit the rate limit. To avoid this you can specify an `OAuth` token by setting `COMPOSER_TOKEN` environment variable. You can use [`GITHUB_TOKEN`](https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token "GITHUB_TOKEN documentation") secret for this purpose.

+### Private Packagist Authentication
+
+If you use Private Packagist for your private composer dependencies, you can set the `PACKAGIST_TOKEN` environment variable to authenticate.

+```
+
+### Manual Composer Authentication
+
+In addition to GitHub or Private Packagist, if you want to authenticate private repositories hosted elsewhere, you can set the `COMPOSER_AUTH_JSON` environment variable with the authentication methods and the credentials in json format.
+Please refer to the authentication section in [`composer documentation`](https://getcomposer.org/doc/articles/authentication-for-private-packages.md "composer documentation") for more details.
