+## Registration
+
+```js
+// add these two lines in your setupTestFrameworkScriptFile:
+// http://facebook.github.io/jest/docs/configuration.html#setuptestframeworkscriptfile-string
+import { registerAssertions } from 'redux-actions-assertions/jest';

+
+## Usage
+
+### .toDispatchActions
+
+> `expect(action).toDispatchActions(expectedActions, done)`
+
+Asserts that when given `action` is dispatched it will dispatch `expectedActions`. `action` can be plain object (action) or function (action creator). `expectedActions` can be can be plain object (action) or function (action creator) or array of objects/functions.
+
+```js
+expect(myActionCreator())
+  .toDispatchActions({ type: 'MY_ACTION_START' }, done);
+```
+
+### .toNotDispatchActions
+
+> `expect(action).toNotDispatchActions(expectedActions, done)`
+
+Asserts that when given `action` is dispatched it will not dispatch `expectedActions`. `action` can be plain object (action) or function (action creator). `expectedActions` can be can be plain object (action) or function (action creator) or array of objects/functions.
+
+```js
+expect(myActionCreator())
+  .toNotDispatchActions({ type: 'MY_ACTION_START' }, done);
+```
+
+### .toDispatchActionsWithState
+
+> `expect(action).toDispatchActionsWithState(state, expectedActions, done)`
+
+Asserts that store initialised with `state` before `action` is dispatched.
+
+```js
+const state = {property: 'value'};
+const expectedActions = [{ type: 'MY_ACTION_START' }, finishActionCreator()];
+expect(myActionCreator())
+  .toDispatchActionsWithState(state, expectedActions, done);
+```
+You can also use its variant `.toNotDispatchActionsWithState`:
+
+```js
+expect(myActionCreator())
+  .toNotDispatchActionsWithState(state, expectedActions, done);
+```
