   - in a web browser, open the temporary URL displayed by the ipython server and start using the ipython notebooks
   - when you are finished, <wrap em>do not forget to kill the ipython server</wrap> by typing ''^C^C'' (2x ''CTRL-C''). Otherwise the server and the python processes started by the server will keep on using resources on the computer
     * Warning! Closing the browser, or using the Logout button in the browser will not stop the ipython server
+===== Working correctly with the notebooks =====
+==== Reminder ====
+  * Make sure you read and understand the [[#how_does_it_work|How does it work?]] section above
+  * If you have a python installed **on your own desktop/laptop**, you can just start a local notebook server and browser with\\ ''jupyter notebook''
+  * **On a remote and shared server**, only start the notebook server and use a local browser to connect to the notebook server through an ssh tunnel
+==== Prerequisites ====
+  * We assume that you have a local web browser installed!\\ Depending on your (local) computer:
+    * **Linux**: you should already be able to open a local terminal, and ''ssh'' is installed by default
+    * **Windows**: you need to know how to open a Windows prompt/command-line (''Windows''+''R'', then open ''cmd'')
+      * Windows 7: and you need to install [[other:win10apps#putty_pageant|Putty]] in order to use ''ssh'':
+      * In the instructions below, replace ''ssh'' with ''plink'' if you are using Windows 7
+==== Digging ssh tunnels ====
+The ssh tunnels will allow you to connect a web browser running locally on your computer to a notebook server running on a remote server
