+# Docker SSH Authorized Keys Challenge
+
+This is a simple challenge utilizing docker-compose to setup a ssh client/control environment where the controller is trying to connect into the client to dump a file.
+
+## Setup
+
+Running `docker-compose up -d --build` will setup a default environment.
+
+Users will be setup on the client using the teamX format.
+Initial user password can be obtained from the container logs of `client`.
+All "scoring" public/private keys will be stored under a local `keys` directory.
+
+## Goal
+
+The goal is to give teams access to login to the `client` container and properly setup a provided public key.
+Once the key is properly setup a file will appear in the appropriate teams home folder.
+Since could take up to a minute to show up after completion.
+
+For added complexity, the `SSHD_CHALLENGE_DIR` exists changing the default AuthorizedKeysFile within SSHD.
+This adds a further challenge since teams will need to checkout the configuration in `/etc/ssh/sshd_config` for the correct structure.
