-## What is Apache Spark?
+## General
+
+### What workloads is Distributed Data Lab suited for?
+
+Distributed Data Lab supports a range of workloads, including:
+
+- Complex analytics.
+- Machine learning tasks.
+- High-speed operations on large datasets.
+
+It offers scalable CPU and GPU instances with flexible node limits, and robust Apache Spark library support.
+
+### What is Apache Spark?
 
 Apache Spark is an open-source unified analytics engine designed for large-scale data processing. It provides an interface for programming entire clusters with implicit data parallelism and fault tolerance. Spark offers high-level APIs in Java, Scala, Python, and R, and an optimized engine that supports general execution graphs.
 
-## How does Apache Spark work?
+### How does Apache Spark work?
 
 Apache Spark processes data in memory, which allows it to perform tasks up to 100 times faster than traditional disk-based processing frameworks like [Hadoop MapReduce](https://fr.wikipedia.org/wiki/MapReduce). It uses Resilient Distributed Datasets (RDDs) to store data across multiple nodes in a cluster and perform parallel operations on this data.
 
-## How am I billed for Distributed Data Lab?
+### How am I billed for Distributed Data Lab?
 
 Distributed Data Lab is billed based on two factors:
 - the main node configuration selected
 - the worker node configuration selected, and the number of worker nodes in the cluster
 
-## Can I upscale or downscale a Distributed Data Lab?
+## Clusters
+
+### Can I upscale or downscale a Distributed Data Lab?
+
+Yes, you can upscale a Data Lab cluster to distribute your workloads across more worker nodes for faster processing. You can also scale it down to zero to reduce costs, while retaining your configuration and context.
+
+You can still access the notebook of a Data Lab cluster with zero worker nodes, but you cannot perform any calculation. You can resume the activity of your cluster by provisioning at least one worker node.
+
+### Can I run a Distributed Data Lab using GPUs?
+
+Yes, you can run your cluster on either CPUs or GPUs. Scaleway leverages Nvidia's RAPIDS Accelerator For Apache Spark, an open-source suite of software libraries and APIs to execute end-to-end data science and analytics pipelines entirely on GPUs. This technology allows for significant acceleration of data processing tasks compared to CPU-based processing.
+
+## Storage
+
+### What data source options are available?
+
+Data Lab natively integrates with Scaleway Object Storage for reading and writing data, making it easy to process data directly from your buckets. Your buckets are accessible using the Scaleway Console, or any other Amazon S3-compatible CLI tool.
+
+### Can I connect to S3 buckets from other cloud providers?
+
+Currently, connections are limited to Scaleway's Object Storage environment.
+
+## Notebook
+
+### What notebook is included with Dedicated Data Labs?
+
+The service provides a JupyterLab notebook running on a dedicated CPU instance, fully integrated with the Apache Spark cluster for seamless data processing and calculations.
 
-Yes, you can upscale a Data Lab cluster to distribute your workloads across a greater number of worker nodes for faster processing. You can also scale it down to zero to reduce costs, while retaining your configuration and context.
+### Can I connect my local JupyterLab to the Data Lab?
 
-You can still access the notebook of a Data Lab cluster with zero worker nodes, but you cannot perform any calculation. You can resume the activity of your cluster by provisioning at least one worker node.
+Remote connections to a Data Lab cluster are currently not supported.

+GPUs (Graphical Processing Units) allow Apache Spark to accelerate computations for tasks that involve large-scale parallel processing, such as machine learning and specific data-analytics, significantly reducing the processing time for massive datasets and preparation for A.I models.

 ## JupyterLab 
 
 JupyterLab is a web-based platform for interactive computing, letting you work with notebooks, code, and data all in one place. It builds on the classic Jupyter Notebook by offering a more flexible and integrated user interface, making it easier to handle various file formats and interactive components.
