Packager.io needs to access the git repository where the code of the application you want to package resides.
For now, the only provider we support is GitHub, so you'll need to have an account set up with them.
If you have a GitHub account, head over to packager.io, and click on the Sign in button on the screen. You will be redirected to the GitHub site, which will ask for the permission to share your repository details with us.
Due to the nature of GitHub OAuth scopes, we are required to ask for read/write permissions on all your repositories, which is far from ideal. We hope to have access to finer-grained scopes in the future.
In the meantime you can have a look at our Security and Privacy policies to better understand what we access, and how we ensure that your code stays safe.
