+Our project is presented in the from of a Julia Jupyter notebook.

+
+## General presentation of notebooks
+
+Notebooks are a user-friendly way of mixing code with printed results and markdown/latex writing.
+
+A notebook is cut in blocks containing either code, printed results or markdown/latex. Each block can be run separately, and all the functions/variables declared in it are stored in the current session.
+
+It is important to note than blocks need preferably be executed from the top down, because the varaibles and function calls used in a block might depend on previous blocks.

+
+## Visualizing our notebook
+
+The simplest way is to go to the [nbviewer](https://nbviewer.jupyter.org/) website and type `https://signolle.iiens.net/files/heldAndKarp.ipynb`
+in the search bar.

+
+Alternatively, you can open the notebook in a notebook editor. For information about installing such an editor, you can go to either the [Jupyter installation page](https://jupyter.org/install) or the [Pluto installation page](https://plutojl.org/#lets-do-it). Note that in order to run the blocks in the notebook rather than just seeing them, you will need to [download and install Julia > 1.4.2](https://julialang.org/downloads/).
+
+## Converting to a classic julia script
+
+If you just want to see/run the code without the printing and block structure, you might want to [install nbconvert](https://nbconvert.readthedocs.io/en/latest/install.html) and run in a shell terminal the following command :
+
+```
+jupyter nbconvert --to script heldAndKarp.ipynb
+```
