How to install Open edX devstack appsembler

Hi, everyone
I want to install Open edX devstack from appsambler (GitHub - appsembler/devstack: Get up and running quickly with edX services), but got some error like this

Cloning into 'amc'...
Warning: Permanently added the RSA host key for IP address 'xxx.xxx.xxx.xxx' to the list of known hosts.
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
make: *** [dev.clone] Error 128

and try another link for installation (tahoe/development_environment_setup.md at master · appsembler/tahoe · GitHub)
but in step 5 I’m not found example server-vars.yml file

please help me to install the Open edX appsembler. or is there another link?
thanks

@taufanbudiman, it looks like you don’t have access to the appsembler/amc repository, which appears to be a private repository, not intended to be used by anyone not associated with Appsembler. So if you need any further support, you will have to get in touch with Appsembler.

Thanks for your feedback
