+## Mocking global and namespaced functions
+
+Mocking and stubbing of global functions works the same as for class methods. Please note, the functions must be in scope - you cannot mock a global function call inside of a node. So if your call crosses an observer, or callfunc bridge, it will not work. This is by design, and there are no plans to provide intra-node global or namespace mocking, at this point.
+
+To enable this feature, set the `isGlobalMethodMockingEnabled` rooibos config parameter to true. **DO NOT** enable this on your ide's bsconfig.json, as it will negatively impact performance and may cause other issues. This setting is not compatible with watch  mode, at this moment.
+
+### Configuration
+In addition to the `isGlobalMethodMockingEnabled`, you use the following config flags:
+
+ - `isGlobalMethodMockingEfficientMode` - default to true, when set causes rooibos to modify only those functions that were mocked or stubbed
+ - `globalMethodMockingExcludedFiles` - files that rooibos will not modify, when adding global mocking or stubbing support.
+
+### Known limitations:
+
+#### You must include default values in your expect calls, even if your invoking code does not use them
+ - if you mock or stub a global or namespaced method, you will have to expect default parameters in your expectCalled invocation, as rooibos will receive the default values.
+
+e.g.
+```
+namespace utils
+  function getModel(name as string, asJson = false as boolean)
+  end function
+end namespace
+
+'in the code
+function getBeatlesModel()
+  utils.getModel("Ringo")
+end function
+
+'in the unit test
+@describe("getBeatlesModel")
+@it("gets ringo")
+function _()
+  'This will fail, because rooibos will receive the asJson param with the default value
+  m.expectCalled(utils.getModel("ringo"))
+
+  'therefore we need to do this
+  m.expectCalled(utils.getModel("ringo", false))
+end function
+```
+
+Note - this will be addressed shortly; pr's are welcome in the interim.
+
+#### There might be some bugs, or unknown issues
+Mocking, of global and namespaced functions is supported; but is a relatively new feature. It is possible that there are some scenarios that are not supported. Please raise issues in the rooibos slack channel, if you spot any anomalies.
