+Este rol instala Docker en hosts Debian.  Además, configura una red
+interna a la que se pueden conectar los contenedores.
+
+## Variables

+* `docker_target_release`: Nombre del release Debian.
+  Valor por defecto: distribución actual del host; si no se puede
+  determinar, se utiliza el valor `stretch`.
+
+* `docker_network_name`: Nombre de la red interna a crear.
+  Valor por defecto: `dockernet`.
+
+## Variables exportadas
+
+El rol exporta la variable `docker_network_name`, que puede ser
+utilizada en los roles sucesivos.
