+
+## Objective
+
+The purpose of this tutorial is to show how to clean data with [Apache Spark](https://spark.apache.org/) inside a [Jupyter Notebook](https://jupyter.org/).
+
+*Data Cleaning* or *Data Cleansing* is the preparation of raw data by detecting and correcting records within a dataset.
+
+The tutorial presents a simple data cleaning with `Notebooks for Apache Spark`.
+
+## Requirements 
+
+- Access to the [OVHcloud control panel](https://www.ovh.com/auth/?action=gotomanager&from=https://www.ovh.co.uk/&ovhSubsidiary=GB){.external}
+- A Public Cloud project
+
+## Instructions
+
+### Upload data
+
+First, download these 2 datasets CSV files locally:
+* [books.csv](https://raw.githubusercontent.com/ovh/data-processing-samples/master/apache_spark_notebook_data_cleaning/books.csv)
+* [ratings.csv](https://raw.githubusercontent.com/ovh/data-processing-samples/master/apache_spark_notebook_data_cleaning/ratings.csv)
+
+Then, from the [OVHcloud Control Panel](https://www.ovh.com/auth/?action=gotomanager&from=https://www.ovh.co.uk/&ovhSubsidiary=GB), go to the Object Storage section, locate your S3 bucket and upload your data by clicking `Add object`{.action}.
+
+Select both files from your computer and add them to the root `/` of your bucket.

+
+### Retrieve bucket credentials
+
+There are a few information that we will need as inputs of the notebook.
+
+First, and while we're on the container page of the [OVHcloud Control Panel](https://www.ovh.com/auth/?action=gotomanager&from=https://www.ovh.co.uk/&ovhSubsidiary=GB) we will copy the `Endpoint` information and save it.
+
+Go back to the Object Storage home page and then to the S3 users tab, copy the user's `access key` and save it.
+
+Finally, click on action "hamburger" at the end of the user row `(...)`{.action} > `View the secret key`{.action}, copy the value and save it.
+
+### Launch and access a Notebook for Apache Spark
+
+From the [OVHcloud Control Panel](https://www.ovh.com/auth/?action=gotomanager&from=https://www.ovh.co.uk/&ovhSubsidiary=GB), go to the Data Processing section and create a new notebook by clicking `Data Processing`{.action} > `Create notebook`{.action}.
+
+You can then reach the `JupyterLab` URL directly from the notebooks list or from the notebook page.
+
+### Experiment with notebook
+
+Now that you have your initial datasets ready on an Object Storage and a notebook running, you could start cleaning this data!
+
+A preview of this notebook can be found on [GitHub](https://github.com/ovh/data-processing-samples/blob/master/apache_spark_notebook_data_cleaning/apache_spark_notebook_data_cleaning_tutorial.ipynb).
+
+### Go further
+
+- Do you want to create a data cleaning job you could replay based on your notebook? [Here it is](https://docs.ovh.com/fr/data-processing/submit-python/).
