 # nomad-vault-login

-Shim service allowing authenticating a Nomad session using Vault
+Shim service allowing authenticating a Nomad session using Vault
+
+The idea is that this service would be run along side Nomad and Vault and proxied on the same hostname so it can write to localstorage. It would then provide a form to allow authentication with Vault and then will retrieve the token and store that in the browser for Nomad to use.
+
+It is, as of now, completely untested and may not work at all.
