 == UI Actions
 
-UI Actions plugins provides API to manage *triggers* and *actions*.
-
-*Trigger* is an abstract description of user's intent to perform an action
-(like user clicking on a value inside chart). It allows us to do runtime
-binding between code from different plugins. For, example one such
-trigger is when somebody applies filters on dashboard; another one is when
-somebody opens a Dashboard panel context menu.
-
-*Actions* are pieces of code that execute in response to a trigger. For example,
-to the dashboard filtering trigger multiple actions can be attached. Once a user
-filters on the dashboard all possible actions are displayed to the user in a
-popup menu and the user has to chose one.
-
-In general this plugin provides:
-
-- Creating custom functionality (actions).
-- Creating custom user interaction events (triggers).
-- Attaching and detaching actions to triggers.
-- Emitting trigger events.
-- Executing actions attached to a given trigger.
-- Exposing a context menu for the user to choose the appropriate action when there are multiple actions attached to a single trigger.
-
-=== Basic usage
-
-To get started, first you need to know a trigger you will attach your actions to.
-You can either pick an existing one, or register your own one:
-
-[source,typescript jsx]
-----
-plugins.uiActions.registerTrigger({
-  id: 'MY_APP_PIE_CHART_CLICK',
-  title: 'Pie chart click',
-  description: 'When user clicks on a pie chart slice.',
-});
-----
-
-Now, when user clicks on a pie slice you need to "trigger" your trigger and
-provide some context data:
-
-[source,typescript jsx]
-----
-plugins.uiActions.getTrigger('MY_APP_PIE_CHART_CLICK').exec({
-  /* Custom context data. */
-});
-----
-
-Finally, your code or developers from other plugins can register UI actions that
-listen for the above trigger and execute some code when the trigger is triggered.
-
-[source,typescript jsx]
-----
-plugins.uiActions.registerAction({
-  id: 'DO_SOMETHING',
-  isCompatible: async (context) => true,
-  execute: async (context) => {
-    // Do something.
-  },
-});
-plugins.uiActions.attachAction('MY_APP_PIE_CHART_CLICK', 'DO_SOMETHING');
-----
-
-Now your `DO_SOMETHING` action will automatically execute when `MY_APP_PIE_CHART_CLICK`
-trigger is triggered; or, if more than one compatible action is attached to
-that trigger, user will be presented with a context menu popup to select one
-action to execute.
+An API for:
+
+- creating custom functionality (`actions`)
+- creating custom user interaction events (`triggers`)
+- attaching and detaching `actions` to `triggers`.
+- emitting `trigger` events
+- executing `actions` attached to a given `trigger`.
+- exposing a context menu for the user to choose the appropriate action when there are multiple actions attached to a single trigger.
