+Installation done on pmod7
+
+```
+conda env create -f jupyterhub-4.0.2_lab3_py3.11 
+
+conda activatejupyterhub-4.0.2_lab3_py3.11
+```
+
+The current production versions of the spawners (e.g. batchspawner-1.0.0) are
+not compatible with jupyterhub-1.0.0. So, one is forced to deploy the
+development versions. This is coded in the yaml file as pip dependency, 
+pointing to the latest commit available
+
+Also, jupyterlab 4 and jupyter-server 2.11 are not yet supported
