 * using [Binder](http://mybinder.org/): [![Binder](http://mybinder.org/badge.svg)](http://mybinder.org/repo/ageron/ml-notebooks)

+
+# Installation
+
+You will need [git](https://git-scm.com/), obviously.
+
+First, clone this repository:
+
+    $ cd {*your development directory*}
+    $ git clone https://github.com/ageron/ml-notebooks.git
+    $ cd ml-notebooks
+
+If you want an isolated environment, you can use [virtualenv](https://virtualenv.readthedocs.org/en/latest/):
+
+    $ virtualenv env
+    $ source ./env/bin/activate
+
+Next, install the required python packages using pip:
+
+    $ pip install -r requirements.txt         # On Linux
+    OR
+    $ pip install -r requirements_macosx.txt  # On MacOSX
+
+Finally, launch Jupyter:
+
+    $ jupyter notebook
+
+This should start the Jupyter server locally, and open a browser window. Click on `index.ipynb` to get started.
