@@ -40,7 +40,7 @@ There are 3 types of options:
 |`outputFormat`| __Enum__. Specify in which format the tests should be outputted. If left on `DEFAULT`, then the value specified in the _EvoMaster Driver_ will be used. But a different value must be chosen if doing Black-Box testing. *Valid values*: `DEFAULT, JAVA_JUNIT_5, JAVA_JUNIT_4, KOTLIN_JUNIT_4, KOTLIN_JUNIT_5, JS_JEST, CSHARP_XUNIT`. *Default value*: `DEFAULT`.|
 |`testTimeout`| __Int__. Enforce timeout (in seconds) in the generated tests. This feature might not be supported in all frameworks. If 0 or negative, the timeout is not applied. *Default value*: `60`.|
 |`blackBox`| __Boolean__. Use EvoMaster in black-box mode. This does not require an EvoMaster Driver up and running. However, you will need to provide further option to specify how to connect to the SUT. *Default value*: `false`.|
-|`bbSwaggerUrl`| __String__. When in black-box mode for REST APIs, specify the URL of where the OpenAPI/Swagger schema can be downloaded from. If the schema is on the local machine, you can use a URL starting with 'file://'. *Constraints*: `URL`. *Default value*: `""`.|
+|`bbSwaggerUrl`| __String__. When in black-box mode for REST APIs, specify the URL of where the OpenAPI/Swagger schema can be downloaded from. If the schema is on the local machine, you can use a URL starting with 'file://'. If the given URL is neither starting with 'file' nor 'http', then it will be treated as a local file path. *Constraints*: `URL`. *Default value*: `""`.|
 |`bbTargetUrl`| __String__. When in black-box mode, specify the URL of where the SUT can be reached, e.g., http://localhost:8080 . In REST, if this is missing, the URL will be inferred from OpenAPI/Swagger schema. In GraphQL, this must point to the entry point of the API, e.g., http://localhost:8080/graphql . *Constraints*: `URL`. *Default value*: `""`.|
 |`ratePerMinute`| __Int__. Rate limiter, of how many actions to do per minute. For example, when making HTTP calls towards an external service, might want to limit the number of calls to avoid bombarding such service (which could end up becoming equivalent to a DoS attack). A value of zero or negative means that no limiter is applied. This is needed only for black-box testing of remote services. *Default value*: `0`.|
 |`header0`| __String__. In black-box testing, we still need to deal with authentication of the HTTP requests. With this parameter it is possible to specify a HTTP header that is going to be added to most requests. This should be provided in the form _name:value_. If more than 1 header is needed, use as well the other options _header1_ and _header2_. *Constraints*: `regex (.+:.+)\|(^$)`. *Default value*: `""`.|
