+The public data sync contains a snapshot of all public data in the ORCID Registry associated with any ORCID record that was created or claimed by an individual. S3 access to use the script is availble to [premium ORCID members](https://orcid.org/about/membership), contact [email protected] to get credentials.
 
 These are Python scripts, based on the Amazon AWS CLI API; it is just a reference implementation intended to show ORCID members how to access the public data sync on demand allowing them to be up to date with the latest public data in the ORCID registry.

 These scripts will synchronize a given folder with the latest content available in the [Amazon S3](https://aws.amazon.com/s3) ORCID data sync repository. The download.py script will fetch all public content available, the sync.py script will sync the content modified since the last time the download.py or the sync.py script ran, since a given number of days back, or since the last 30 days if none of the options is provided.
 
 When the synchronization process starts, the script will create a set of folders that will contain all ORCID records distributed by the [checksum](http://support.orcid.org/knowledgebase/articles/116780-structure-of-the-orcid-identifier) of the ORCID ID.

+Before setting up the sync process you may want to consider if one of these options will works better for you. Contact [email protected] for more information or suggestions based on your use case.

+### Webhooks
+
+Premium members can [set up webhooks](https://github.com/ORCID/ORCID-Source/blob/master/orcid-api-web/tutorial/webhooks.md) to get notifications when specific records they are watching are updated.

+### The ORCID API
+
+You may be able to [search](https://github.com/ORCID/ORCID-Source/blob/master/orcid-api-web/tutorial/search.md) the [ORCID API](https://github.com/ORCID/ORCID-Source/tree/master/orcid-api-web), searching by last modified date is supported. 
+
+### Public Datafile
+
+Once a year a static [public data file](https://support.orcid.org/hc/en-us/articles/360006897394-How-do-I-get-the-public-data-file-) of the ORCID Registry is published under a CC0 license and can be downloaded by anyone.

+## Sync Quick setup
 
 1. Ensure that you are set up to handle the sync files. Verify you have at least 250GB available in your hard drive and are able to process the files (each ORCID records is stored as multiple files). You may want to first look at the [ORCID Public Data File](https://orcid.org/content/download-file) to see an example of what to expect when using the sycn process.

 We only offer the sycn files in ORCID XML using the [2.0 schema](https://github.com/ORCID/ORCID-Source/tree/master/orcid-model/src/main/resources/record_2.0). If you are working with JSON, you may want to consider using the [ORCID Converstion Utility](https://github.com/ORCID/orcid-conversion-lib)
