 # Docker support for the NP-TMcode project
 
-This Dockerfile allows to create mainly:
+## Using the pre-built image
+The current version of NP-TMcode (M8.03) has been bundled in a pre-built `docker` image, distributed via `https://hub.docker.com/`. To use this image, run the command:
+
+   > docker run -it gmulas/np-tmcode-run:M8 /bin/bash
+
+The image will be automatically downloaded, if it is not available in the system, then it will be run in interactive mode, starting a shell session. Follow the instructions provided in Sec. 3.4.1 of the Release Notes document to proceed with testing and code use.
+
+## Building a local image
+A local image containing the necessary code requirements and binary files can be built through the Dockerfile provided along with the code. This Dockerfile allows to create mainly:
 
 - the np-tmcode image that is used by the gitlab pipeline runner to test compile and execution of requested merges
 - the np-tmcode-run image, that contains only the pre-built executables, python test scripts, compiled documentation, and the minimal runtime to run them

+## Using the pre-built image
+The current version of NP-TMcode (M8.03) has been bundled in a pre-built `singularity` image, distributed at `https://www.ict.inaf.it/gitlab/giacomo.mulas/np-tmcode-singularity/-/releases/np-tmcode-singularity-run-M8.03`. To use this image, download and unpack the pre-built image bundle, then place the `np-tmcode-run.sif` file in the `containers/singularity` folder of the NP-TMcode project.
