+Jupyter Notebooks are files which allows you to combine \emph{Code} and
+\emph{Markdown} cells in one single document. The code cells, allow you
+to interactively run python code and print and plot data in your
+document. If you wish to update or change data your code you can re-run
+the cell to update the output. The markdown cells allows you to write
+text, titles and insert images in your documentation using the markup
+language \emph{Markdown}.
+
+To start a new notebook select
+\texttt{File\ \textgreater{}\ New\ \textgreater{}\ Notebook} or right
+click the file browser and select \texttt{New\ notebook}, this will
+prompt you to select a kernel (the Jupyter notebook ``engine''). For
+now, just select the default Kernel 3. This will start a new fresh
+kernel for us to use. Next, it's recommended to rename the file.
+
+Now that we have a blank notebook we can start to add cells. Add a cell
+and change the type to Markdown. Add a title with the hash symbol
+(\texttt{\#}). As shown below.
+
+\begin{Shaded}
+\begin{Highlighting}[]
+\FunctionTok{\# Title here}
+\end{Highlighting}
+\end{Shaded}
+
+Press \texttt{Shift\ +\ Enter} to run the cell. You just entered created
+your first markdown cell. Now let's do the same but instead select code
+as the cell type, we're going to add some python code to the document.
+
+\begin{Shaded}
+\begin{Highlighting}[]
+\NormalTok{x }\OperatorTok{=} \DecValTok{4}
+\NormalTok{y }\OperatorTok{=} \DecValTok{3}
+
+\NormalTok{x}\OperatorTok{**}\DecValTok{2}\OperatorTok{+}\DecValTok{2}\OperatorTok{*}\NormalTok{y}
+\end{Highlighting}
+\end{Shaded}
+
+Again, run the cell and see what happens. You should've gotten an output
+of \texttt{22}. You can now use the notebook as a calculator, but there
+is so much more we can do.
+
+The order of running code matters. Think of the code cells as code
+snippets. Every time you run a cell variable will be updated. This means
+that the current state of all variables, functions, and imports depends
+on the history of what cells have been executed and in what order. In
+other words, if you run a later cell before running an earlier one that
+defines a variable or function it needs, you will get an error. If you
+change a variable in one cell and rerun it, that new value immediately
+affects the results of any cells that use that variable afterward ---
+but not any previously run results unless you rerun them too. Variables
+and imports persist in memory between cells, but only based on the
+current session state --- if you restart the kernel, you lose all
+previous definitions unless you re-run the necessary cells.
+
+Because of this, it's best practice to; Run cells in order, restart the
+kernel and run all cells
+(\texttt{Kernel\ -\textgreater{}\ Restart\ \&\ Run\ All}) to make sure
+everything works cleanly and predictably and lastly, initialize
+important variables or imports in early cells, so they are always
+defined before they are needed.
