-I upgraded the frontend (jquery@3.7.1, bootstrap@5.3.3) and backend (pytorch==2.2.2, torchaudio==2.2.2) libraries. Should work also with pytorch > 2.2.2, but right now I can't try it on macOS intel.
+I upgraded the frontend (jquery@3.7.1, bootstrap@5.3.3) and backend (pytorch==2.5.1, torchaudio==2.5.1) libraries. On macOS intel it's possible to install from [pypi.org](https://pypi.org/project/torch/) only until the library version [2.2.2](https://pypi.org/project/torch/2.2.2/)

+## Docker version
+
+Build the docker image this way:
+
+```bash
+# clean any old active containers
+docker stop $(docker ps -a -q); docker rm $(docker ps -a -q)
+
+# build the base docker image
+docker build . --progress=plain --tag aip_trainer
+```
+
+Run the container (keep it on background) and show logs
+
+```bash
+docker run -d -p 3000:3000 --name aip_trainer aip_trainer;docker logs -f aip_trainer
+```
