Documentation
Here you will find all the documentation related to the Device Management Kit and the signers that come along with it.
This project is still in early development so we allow ourselves to make breaking changes regarding the usage of the Libraries.
That’s why any feedback is relevant for us in order to be able to make it stable as soon as possible. Get in touch with us on the Ledger Discord server to provide your feedbacks.
You can follow the migration guidelines for the DMK here and for the signers here.
Glossary
Throughout the documentation we use the following acronyms:
- DMK: Device Management Kit
