Configuration options and information for OF-DL

## 📄️ Authentication

Current Method (versions >= 1.9.0)

## 📄️ CDM (optional, but recommended)

Without Widevine/CDM keys, OF DL uses the 3rd party website cdrm-project.org for decrypting DRM videos. With keys, OF DL directly communicates with OnlyFans. It is highly recommended to use keys, both in case the cdrm-project site is having issues (which occur frequently, in our experience) and it will result in faster download speeds, too. However, this is optional, as things will work as long as cdrm-project is functional.
