 ## Install Procedure using CANDI
 To install from scratch all the needed library you can look to the automatic installation procedure provided by [CANDI](https://github.com/koecher/candi) developed Uwe Köcher.
 
+## Install Procedure using spack

 ## Install Procedure using Docker
 We provide the possibility of using Docker as a tool to provide a fully operational environment for our library. To use such tool you need to install Docker following the [instructions](https://docs.docker.com/engine/installation/) provided by its authors. Then you can execute the following command line instruction 
 
-	docker run -v `pwd`:/pwd_to_your_own_directory/ -i -t mathlab/deal2lkit:v8.5.0-debugrelease bash
+	docker run -v `pwd`:/pwd_to_your_own_directory/ -i -t mathlab/deal2lkit:latest bash
 
 to retrieve the environment. In such a shell you can easily compile the $\pi$-BEM library following its own instructions.
