 5. Send the data, metadata and some extra information to the EarthCODE team.
 
-Below you will find guides to the whole process, we recomend starting with the introductory notebook.
+# Getting Started with PRR Metadata Creation
 
-- [Generating a STAC Collection for the PRR(Introduction)](./PRR_STAC_introduction.ipynb) - A notebook explaining how to create the required PRR metadata. It describes the steps in detail and uses a relatively simple example, with a single .nc raster data file.
-- [Generating STAC collections with zarr files](./prr_zarr.ipynb) - Example how to generate metadata for a product with zarr files.
-- [Generating a STAC Collection for the PRR (Multiple file types)](./example_tccas.ipynb) - Example how to generate metadata for a more complicated dataset which has multiple types of data and different file formats.
-- [Generating a STAC Collection for the PRR(Large dataset for multiple regions)](./Creating%20STAC%20Catalog_from_PRR_example.ipynb) - Example how to generate metadata for a large dataset that has multiple disjoint regions.
+These notebooks are designed for users who are new to the process of publishing data to the ESA Project Results Repository (PRR). They provide step-by-step guidance on how to generate STAC Collections that meet PRR ingestion requirements. 
+Whether you're working with a single raster file or a large, multi-format dataset, notebooks below will assist you in this process. 
 
-If you are interested in exploring/downloading PRR data you can use this notebook as a guide:
-- [ESA Project Results Repository (PRR) Data Access and Collections Preview](./PRR_STAC_download_example.ipynb) - A notebook explaining how Item Catalogs should be created, uses raster data.
+- [Generating a STAC Collection for the PRR (Introduction)](./PRR_STAC_introduction.ipynb) - Detailed explanation on how to create valid metadata to ingest simple raster data file (.nc) into PRR. 
+- [Generating a STAC Collection for the PRR (Multiple file types)](./example_tccas.ipynb) - Example how to generate metadata for a more complex dataset with varied data types and formats.
+- [Generating a STAC Collection for the PRR (Large dataset for multiple regions)](./Creating%20STAC%20Catalog_from_PRR_example.ipynb) - Example focuses on handling large dataset across multiple disjoint regions.
