const backendHelp = `
The SSH backend generates credentials allowing clients to establish SSH
connections to remote hosts.
There are three variants of the backend, which generate different types of
credentials: dynamic keys, One-Time Passwords (OTPs) and certificate authority. The desired behavior
is role-specific and chosen at role creation time with the 'key_type'
parameter.
Please see the backend documentation for a thorough description of both
types. The Vault team strongly recommends the OTP type.
After mounting this backend, before generating credentials, configure the
backend's lease behavior using the 'config/lease' endpoint and create roles
using the 'roles/' endpoint.
