 HCl is a command-line tool for interacting with Harvest time sheets using the
 [Harvest time tracking API][1].
 
+## Quick Start
+
+NOTE This software is nowhere near complete. Currently the only implemented
+feature is a simple view of today's timesheet. To try it out:
+
+ $ cp hcl_conf.yml.example hcl_conf.yml
+ $ $EDITOR hcl_conf.yml
+ $ ./bin/hcl show
+
+### Prerequisites
+
+This software depends on the Curb gem. To install:
+
+ $ sudo gem install curb
+
 ## Usage
 
+    hcl [opts] show [date]
     hcl [opts] add <project> <task> <duration> [msg]
     hcl [opts] rm [entry_id]
     hcl [opts] start <project> <task> [msg]
     hcl [opts] stop [msg]
-    hcl [opts] show [date]
 
 ## TODO
 
  * Implement time-tracking API methods:
-   - get daily time sheet
+   - display today's time sheet (done)
+   - display any time sheet by date
    - get time sheet entry
    - toggle a timer
    - post a time sheet entry
    - delete a time sheet entry
    - update a time sheet entry
+ * command-line configuration
+ * search ~/.hcl_config for configuration
+ * integrate timesheet functionality into aiaio's [harvest gem][2]
