+# action
+
+## Description
+Action to execute.
+
+Actions are executed to perform the following regulator operations:
+* [presence_detection](presence_detection.md)
+* [configuration](configuration.md)
+* [sensor_monitoring](sensor_monitoring.md)
+
+Many actions read from or write to a hardware device.  Initially this is the
+[device](device.md) that contains the regulator operation.  However, the device
+can be changed using the [set_device](set_device.md) action.

+### Notes
+* You must specify exactly one action type property, such as "i2c_write_byte"
+  or "run_rule".
+
+## Return Value
+When the action completes, it returns a true or false value.  The documentation
+for the specified action type describes what value will be returned.
+
+## Examples
+```
+{
+  "comments": [ "Set frequency to 800kHz" ],
+  "i2c_write_byte": {
+    "register": "0x2C",
+    "value": "0x0F"
+  }
+}
+
+{
+  "run_rule": "set_voltage_rule"
+}

+# rule
+
+## Description
+A rule is a sequence of actions that can be shared by multiple regulators in
+the config file.  Rules define a standard way to perform an operation.  Rules
+are used to minimize duplication in the config file.
+
+For example, the following action sequences might be sharable using a rule:
+* Actions that set the output voltage of a regulator rail
+* Actions that read all the sensors of a regulator rail
+* Actions that detect down-level hardware using version registers
+
+## Properties
+| Name | Required | Type | Description |
+| :--- | :------: | :--- | :---------- |
+| comments | no | array of strings | One or more comment lines describing this rule. |
+| id | yes | string | Unique ID for this rule.  Can only contain letters (A-Z, a-z), numbers (0-9), and underscore (\_). |
+| actions | yes | array of [actions](action.md) | One or more actions to execute. |
+
+## Return Value
+Return value of the last action in the "actions" property.
+
+## Example
+```
+{
+  "comments": [ "Sets output voltage of PAGE 0 of a PMBus regulator" ],
+  "id": "set_page0_voltage_rule",
+  "actions": [
+    { "i2c_write_byte": { "register": "0x00", "value": "0x00" } },
+    { "pmbus_write_vout_command": { "format": "linear" } }
+  ]
+}
+
+... later in the config file ...
+
+"configuration": {
+  "volts": 1.03,
+  "rule_id": "set_page0_voltage_rule"
