 All configuration to execute Jupyter Notebooks is pre-defined for the sample dataset in the [configuration YAML file](src/config/config.yaml): paths, filenames, API parameters, user-defined numerical parameters.
 Data flow within the Data4Land tool can be also explored on the overarching diagram:![diagram](visualisation/workflow.png).
 
+### Installation
+Each Jupyter Notebook is recommended to execute through a built Docker to ensure that all dependencies needed are installed correctly. Otherwise, some of the libraries used by Data4Land may face issues. Multiple ways to configure and install Docker are available:
+[Windows](https://www.docker.com/products/docker-desktop/), [Linux](https://docs.docker.com/desktop/setup/install/linux/), [Mac](https://docs.docker.com/desktop/setup/install/mac-install/).
+Once Docker is installed, user need to:
+- download the software repository
+- in command line run 'cd /path/data4land' (navigate to the working directory on local machine, replace the directory name if required)
+- then run 'docker-compose up' (this will run all Docker commands and start up a Jupyter server)
+
+To execute Jupyter Notebook users need to either: 
+- navigate to http:localhost:9999 or
+- copy URL with token from the console and paste it to browser or another tool used to run Jupyter Notebook (for example, *http://localhost:9999/?token=abcd123400000000000000000000000*)
+
+Now, everything is prepared to execute the Jupyter Notebooks within a Docker environment.

+#### Impact
+The example of follow-up calculations of habitat connectivity based on non-enriched and enriched LULC datasets is given [here](stats/) to illustrate the significant impact of enriched raster pixels.

 #### Further development

 - Implement iterations over multiple LULC files (by year and location) and multiple OSM requests (iterating over the combination of filename-yearname).
 - For use case studies: revisit Catalonian government data and decide on its usage, whether it can support OSM data or not.
