+### Setting Project, Location, Token
+
+For cloud providers:
+- Azure
+- Bedrock
+- GCP
+- Watson AI 
+
+you might need to set additional parameters. LiteLLM provides a common set of params, that we map across all providers. 
+
+|      | LiteLLM param | Watson       | Vertex AI    | Azure        | Bedrock      |
+|------|--------------|--------------|--------------|--------------|--------------|
+| Project | project | watsonx_project | vertex_project | n/a | n/a |
+| Region | region_name | watsonx_region_name | vertex_location | n/a | aws_region_name |
+| Token | token | watsonx_token or token | n/a | azure_ad_token | n/a |
+
+If you want, you can call them by their provider-specific params as well.
