+#### <a id="activate"></a> [≡](#contents) [`activate: (obs: Kefir.Observable) => void`](#activate)
+
+`activate` is a simple helper function to turn a stream on.
+
+#### <a id="deactivate"></a> [≡](#contents) [`deactivate: (obs: Kefir.Observable) => void`](#deactivate)
+
+`deactivate` is a simple helper function to turn a stream off. It can turn off streams that were activated with `activate`. Streams turned on through other means (direct call to `on{Value|Error|End|Any}`, use of `observe`, etc.) need to be deactivated through their complementary mechanisms.
+
+#### <a id="send"></a> [≡](#contents) [`send: (obs: Kefir.Observable, values: Array<Event<T>>) => obs`](#send)
+
+`send` is a helper function for emitting values into a given observable. Note that the second parameter is an array of values to emit from the observable. The `Event` is generated by the `value`, `error`, and `end` functions. For all three of these functions, the optional `options` object is not needed.
+
+#### <a id="value"></a> [≡](#contents) [`value: (value, options: ?{ current }) => Event<Value>`](#value)
+
+#### <a id="error"></a> [≡](#contents) [`error: (error, options: ?{ current }) => Event<Error>`](#error)
+
+#### <a id="end"></a> [≡](#contents) [`end: (options: ?{ current }) => Event<End>`](#end)
+
+`value` and `error` take a value or error and an optional `options` object and return an `Event` object that can be passed to `send`, `emit`, or `emitInTime`. `end` does not take this value, as the `end` event in Kefir does not send a value with it.
+
+When passing to `send`, the `options` object is ignored. `options` is used by `emit` and `emitInTime` (both described below) to determine whether the event should be treated as a `Kefir.Property`'s current event, error, or end.
+
+#### <a id="stream"></a> [≡](#contents) [`stream: () => Kefir.Stream`](#stream)
+
+#### <a id="prop"></a> [≡](#contents) [`prop: () => Kefir.Property`](#prop)
+
+#### <a id="pool"></a> [≡](#contents) [`pool: () => Kefir.Pool`](#pool)
+
+`stream`, `prop`, and `pool` are helper functions to create empty streams, properties, and pools. These can be used as mock sources to send values into. They have no other behavior.
