 # Datastory Weekly Chart
 This repository contains data and analysis for the [Datastory Weekly Charts](https://datastory.org/sv/veckans-graf) which are posted on Datastory.org and on social media.
 
+## Run the code in the cloud
+The Jupyter notebooks within this repository can be run using mybinder.org, just
+press the 'launch: binder' button above.
+
 ## Installation
+To work with the notebooks on your own computer, we recommend to [download and
+install Python as part of the anaconda
+distribution](https://www.anaconda.com/distribution/). That way, you get `git`
+to fetch the source code from this repository and Jupyter installed for you.
+
+To install the Python dependencies required for this project, do the following
+from a terminal or command prompt.
+
+```sh
+# get the content of this git repository
+git clone https://github.com/datastory-org/weekly-chart
+
+# enter the weekly-chart directory
+cd weekly-chart
+
+# install pipenv (https://pipenv.readthedocs.io)
+pip install pipenv
+
+# install the Python dependencies from the Pipfile
+pipenv install
+
+# enter the environment
+pipenv shell
 
-To run the notebooks, you need to install the packages listed in the `Pipfile`. The easiest way is to use [Pipenv](https://pipenv.readthedocs.io/en/latest/): `pipenv install`. This will install all dependencies as well as the local `src` package that contain some utility functions that are used in various notebooks.
+# start jupyter lab to work with the notebooks
+jupyter lab
+```
 
-An additional dependency (ImageMagick) is needed to generate GIFs. Please refer to the ImageMagick website for installation documentation.
+> **NOTE:** You also need [ImageMagick](https://imagemagick.org) to generate
+> GIFs, see their instructions on how to install it.
 
 ## Data

 ## Styling
-To create your own style, make a copy of the `assets/datastory.mplstyle` stylesheet to the location of your local matplotlib configuration directory (which can be found with `matplotlib.get_configdir()`). Assuming the config dir is located at `~/.matplotlib/`, move the stylesheet to `~/.matplotlib/stylelib/your-name.mplstyle`. Now you can use `plt.style.use("your-style")` to create custom styled charts.
+To adjust the style of the plots, modify `assets/datastory.mplstyle`.
 
 Unfortunately, some styling options are not customizable via stylesheets and have to be configured in code, which is what the `ds_plot` (in src/plot) function is for. Whenever possible, initialize your plots with the command `fig, ax = ds_plot()` and all basic styling should be set up appropriately.
