+  "Sets a wait strategy to the container.
+   Supports :http, :health and :log as strategies. 
+  
+  ## HTTP Strategy
+  The :http strategy will only accept the container as initialized if it can be accessed 
+  via HTTP. It accepts a path, a port, a vector of status codes, a boolean that specifies 
+  if TLS is enabled, a read timeout in seconds and a map with basic credentials, containing 
+  username and password. Only the path is required, all others are optional. 
+  Example:
+  
+  ```clojure
+  (wait {:strategy :http
+         :port 80
+         :path \"/\"
+         :status-codes [200 201]
+         :tls true
+         :read-timeout 5
+         :basic-credentials {:username \"user\"
+                             :password \"password\"}}
+        container))
+  ```
+  ## Health Strategy
+  TBD
+
+  ## Log Strategy
+  TBD"
