+# Commercial Support Listings Policy
+
+This project provides a public *Commercial Support* section as a courtesy to vendors. Inclusion does **not imply endorsement, verification, or evaluation** by the project maintainers.
+
+## Content
+
+Listings will include:
+
+- **Vendor name**
+- **Link** to the vendor's chosen landing page for more information
+- **Information**
+ - _Contact_ one or more links, URLs, or contact information
+ - _Location_ where the primary location of the vendor is, including time zone
+ - _Supported Regions_ regions where the vendor offers services
+ - _Logo_ a logo in a common image format suitable for display in varying sizes
+- **Listing of Common Services** These categories are set by OIE and are meant to give a quick overview of services offered. If these categories change, current vendors will be contacted to update their listing.
+ - _Contributor_ a link to open-source contribututions by the vendor
+ - _Integration and Interface Services_ a yes/no indication if the vendor provides services to implement, support, or alter integrations running on OIE
+ - _Migration from Other Engines_ a yes/no indication if the vendor provides services to migrate from other engines to OIE
+ - _Cloud Hosting_ a yes/no indication if the vendor provides hosting services
+ - _Managed Support_ a yes/no indication if the vendor provides managed support services
+ - _Custom Development_ a yes/no indication if the vendor provides custom development services 
+ - _Training_ a yes/no indication if the vendor provides training for customers to use OIE
+- **Additional Information** vendors may include any additional information about your services, your company, your staff, etc. 
+- **References** to the vendors participation within the community. This includes but is not limited to links to PRs, links to forks, or community commentary about their participation. 
+
+The project reserves the right to:
+
+- Control and limit tag selection for clarity and space
+- Deny or remove listings that violate community standards or appear misleading
+
+The project shall not mediate disputes between vendors and clients. We are offering a listing, not a certification or endorsement. 
+
+## Vendor Expectations
+
+Vendors are expected to follow community guidelines.
+
+Vendors can be de-listed by a simple majority vote of the steering committee. We expect to never have to do this. 
+
+## Limitations and Disclaimer
+
+All linked content is maintained by the vendor. The project does **not**:
+
+- Verify any claims made by vendors
+- Support or guarantee vendor services
+- Intervene in disputes between users and vendors
+
+Users should **perform their own due diligence** before engaging with any listed vendor. 
+
+## Get Listed
+
+The process to get listed is enumerated in the [vendors repository](https://github.com/OpenIntegrationEngine/vendors).
