## Overview
-This directory contains applications for configuring and monitoring power
-sequencer and related devices that support JSON-driven configuration.
+This directory is a repository for applications which perform power control or
+configure or monitor power sequencer or related devices. These applications may
+support JSON-driven configuration.
+
+The currently implemented application is named `phosphor-power-control` and
+supports GPIO based power control and power sequencer monitoring with specific
+support for the UCD90320 device available.
+
+## JSON Configuration Files
+
+Configuration files are stored in the `config_files` directory.
+See the [Configuration File README](config_files/README.md) for details on the
+format of power sequencer configuration files.
+
+## Source Files
+
+Source files are stored in the `src` directory.
+See the [Source Files README](src/README.md) for details on the design of the
+application source.
