# Introduction

After you've created a Site, configure the data access settings so that volunteers can interact with your Site's contents.

Sharing is the general term that describes how you control who sees what in Salesforce. Sharing settings control users' access to the Contact, Account, Campaign, Volunteer Jobs, and other Volunteers for Salesforce objects.

- [Define Sharing Rules](https://help.salesforce.com/s/articleView?id=sfdo.v4s_setup_define_sharing_rules.htm&release=264.0.0&type=5 "If you have an existing Volunteers for Salesforce org that has been upgraded to the Salesforce Winter '20 release and have enabled the Secure Guest User Record Access setting, create sharing rules to give guest users access to your records.")
- [Configure Data Access for Visualforce Pages](https://help.salesforce.com/s/articleView?id=sfdo.v4s_setup_data_access_vf.htm&release=264.0.0&type=5 "Volunteers for Salesforce is built on Visualforce, which is a way to create custom user interfaces for Salesforce objects and data. Configure access to Visualforce pages for your volunteers user profile.")
- [Configure Object and Field Permissions in Public Access Settings](https://help.salesforce.com/s/articleView?id=sfdo.v4s_setup_website_config_perms.htm&release=264.0.0&type=5 "The last step in configuring data access is making sure your Site's public access settings give permission to read, create, and edit the dozen or so objects that Volunteers for Salesforce needs to do its job.")
- [Configure Site Guest User Access for Volunteers](https://help.salesforce.com/s/articleView?id=sfdo.v4s_setup_config_site_guest_user_access_volunteers.htm&release=264.0.0&type=5 "The System Admin must select Grant Guest Users Update Access in Volunteer Settings to allow guest users to update records shared with them.")

Tip If data access and visibility in Salesforce are unfamiliar territory, the [Data Security](https://trailhead.salesforce.com/modules/data_security/units/data_security_overview) Trailhead module is a great place to get your bearings first. Then come back and get comfortable, because we're going to linger a while in the Setup menu configuring data access.
