+The `CommandsManager` is a class defined in the `@ohif/core` project.
+The Commands Manager tracks named commands (or functions) that are scoped to
 a context. When we attempt to run a command with a given name, we look for it
-in our active contexts. If found, we run the command, passing in any application
+in our active contexts, in the order specified.
+If found, we run the command, passing in any application
 or call specific data specified in the command's definition.
 
-> Note: A single instance of `CommandsManager` should be defined in the consuming application, and it is used when constructing the `ExtensionManager`.
+The order specified is the REVERSE of the order the modules are registered in
+for the mode dependency.  That is, the last module registered has the highest priority
+and will be searched first for commands.  This has nothing to do with when the
+command itself is registered, although registrations for the same command in different
+modules in the same context will also use last registration wins.

 ### Instantiating
 
-When we instantiate the `CommandsManager`, we are passing two methods:
-
-- `getAppState` - Should return the application's state when called (Not implemented in `v3`)
-- `getActiveContexts` - Should return the application's active contexts when
-  called
-
-These methods are used internally to help determine which commands are currently
-valid, and how to provide them with any state they may need at the time they are
-called.
-
-```js title="platform/app/src/appInit.js"
-const commandsManagerConfig = {
-  getAppState: () => {},
-  /** Used by commands to determine active context */
-  getActiveContexts: () => [
-    'VIEWER',
-    'DEFAULT',
-    'ACTIVE_VIEWPORT::CORNERSTONE',
-  ],
-};
-
-const commandsManager = new CommandsManager(commandsManagerConfig);
-```
+No methods or configuration is used within the construction.
 
 
 ## Commands/Context Registration
-The `ExtensionManager` handles registering commands and creating contexts, so you don't need to register all your commands manually. Simply, create a `commandsModule` in your extension, and it will get automatically registered in the `context` provided.
