+
+# Installation
+These steps are for MacOS, with [```brew```](brew.sh) and ```python3``` already installed.
+
+## Installing Julia
+
+```sh
+brew install julia
+```
+
+## Installing JupyterLab and IJulia kernel
+
+### IJulia kernel
+
+Inside the julia REPL:
+```julia
+using Pkg
+Pkg.add("IJulia")
+```
+
+A simple notebook experience can be obtained by simply running ```noteboot()```, which will install in a separate [```conda```](https://docs.conda.io/en/latest/) environment the needed python packages.
+
+### JupyterLab
+
+A separate environment with [```virtualenv```](https://pypi.org/project/virtualenv/) or [```virtualenvwrapper```](https://pypi.org/project/virtualenvwrapper/) is recommended.
+
+```sh
+pip install jupyterlab
+```
+
+# Running
+
+To run simply start the notebook with ```jupyter lab``` , the julia kernel should be automatically detected.
