 # HTTP API GATEWAY
 
-## Direct Gateway
-
-Requests will be directly redirect to the Service set in the URI.   
-For example, given the configuration
-
-```yaml
-gateway:
-  direct: true
-```
-
-- `{host}/api/my-service/foo/bar` will be proxied to `{my-service-endpoint}/foo/bar`
-- `{host}/api/my-service/my-endpoint` will be proxied to `{my-service-endpoint}/my-endpoint`
-
-## Routed Gateway
-
-Requests will be re-routed based on configured routes and context.  
-For example, given the configuration
-
-```yaml
-gateway:
-  direct: false
-  routes:
-    my-service:
-      service-id: my-service-id
-      mapping:
-        - route: foo-bar
-          context: /foo/bar
-        - route: my-endpoint
-    some-remote-application:
-       uri: https://example.com
-       mapping:
-          - route: example
-```
-
-- `{host}/api/foo-bar` will be proxied to `{service-endpoint}/foo/bar`
-- `{host}/api/my-endpoint` will be proxied to `{service-endpoint}/my-endpoint`
-- `{host}/api/example` will be proxied to `https://example.com`
