+### Usage
+
+To use the tools and scripts in this repository, you just need to clone it and ensure the config.ini file is properly configured as described above.
+
+#### Executing the scripts:
+
+Execute the scripts independently in the following recommended order:
+##### EMPIAR mapping
+```
+fetch_empiar.py: python fetch_empiar.py -w <output_dir_to_store_annotated_empiar_files> -f <path_to_empiar_metadata_files>
+```
+##### Publication mapping
+```
+fetch_pubmed.py: python fetch_pubmed.py -w <output_dir_to_store_annotated_pubmed_files> -f <path_to_emdb_metadata_files>
+```
+##### Protein, complexes and ligands mapping
+```
+added_annotations.py: python added_annotations.py -w <output_dir_to_store_added_annotations> -f <path_to_emdb_metadata_files> --all -t <number_of_threads>
+```
+##### AlphaFold DB mapping
+```
+fetch_afdb.py: python fetch_afdb.py -w <output_dir_to_store_annotated_alphafdb_files>
+```
+##### Write files
+```
+write_xml.py: python write_xml.py <output_dir_to_store_EMICSS_xml_files>
+```
