 * `serverType` - either `SAS9` or `SASVIYA`.
 * `serverUrl` - the location (including http protocol and port) of the SAS Server. Can be omitted, eg if serving directly from the SAS Web Server, or in streaming mode.
 * `debug` - if `true` then SAS Logs and extra debug information is returned.
-* `useComputeApi` - if `true` and the serverType is `SASVIYA` then the REST APIs will be called directly (rather than using the JES web service).
-* `contextName` - if missing or blank, and `useComputeApi` is `true` and `serverType` is `SASVIYA` then the JES API will be used.
+* `LoginMechanism` - either `Default` or `Redirected`.  If `Redirected` then authentication occurs through the injection of an additional screen, which contains the SASLogon prompt.  This allows for more complex authentication flows (such as 2FA) and avoids the need to handle passwords in the application itself.  The styling of the redirect flow can also be modified.  If left at "Default" then the developer must capture the username and password and use these with the `.login()` method.
+* `useComputeApi` - Only relevant when the serverType is `SASVIYA`. If `true` the [Compute API](#using-the-compute-api) is used.  If `false` the [JES API](#using-the-jes-api) is used.  If `null` or `undefined` the [Web](#using-jes-web-app) approach is used.
+* `contextName` - Compute context on which the requests will be called.  If missing or not provided, defaults to `Job Execution Compute context`.
 
 The adapter supports a number of approaches for interfacing with Viya (`serverType` is `SASVIYA`).  For maximum performance, be sure to [configure your compute context](https://sasjs.io/guide-viya/#shared-account-and-server-re-use) with `reuseServerProcesses` as `true` and a system account in `runServerAs`.  This functionality is available since Viya 3.5.  This configuration is supported when [creating contexts using the CLI](https://sasjs.io/sasjs-cli-context/#sasjs-context-create).
 
 ### Using JES Web App
 
-In this setup, all requests are routed through the JES web app, at `YOURSERVER/SASJobExecution`.  This is the most reliable method, and also the slowest.  One request is made to the JES app, and remaining requests (getting job uri, session spawning, passing parameters, running the program, fetching the log) are made on the SAS server by the JES app.

-```
-{
-  appLoc:"/Your/Path",
-  serverType:"SASVIYA"
-}

-
-### Using the JES API
-Here we are running Jobs using the Job Execution Service except this time we are making the requests directly using the REST API instead of through the JES Web App.  This is helpful when we need to call web services outside of a browser (eg with the SASjs CLI or other commandline tools).  To save one network request, the adapter prefetches the JOB URIs and passes them in the `__job` parameter.

To save one network request, the adapter prefetches the JOB URIs and passes them in the `__job` parameter.  Depending on your network bandwidth, it may or may not be faster than the JES Web approach.
+
+This approach (`useComputeApi: false`) also ensures that jobs are displayed in Environment Manager.

+  appLoc:"/Your/Path",
+  serverType:"SASVIYA",
+  useComputeApi: false,
+  contextName: 'yourComputeContext'
 }
 ```
 
 ### Using the Compute API
-This approach is by far the fastest, as a result of the optimisations we have built into the adapter.  With this configuration, in the first sasjs request, we take a URI map of the services in the target folder, and create a session manager - which spawns an extra session.  The next time a request is made, the adapter will use the 'hot' session.  Sessions are deleted after every use, which actually makes this _less_ resource intensive than a typical JES web app, in which all sessions are kept alive by default for 15 minutes.
