+## Issue Time Estimates
+GitLab issues allow for time tracking. The following time units are currently available:
+
+months (mo)
+weeks (w)
+days (d)
+hours (h)
+minutes (m)
+
+Conversion rates are 1mo = 4w, 1w = 5d and 1d = 8h.

 ## Making API Calls
 The API has been broken up into sub APIs classes to make it easier to learn and to separate concerns.  Following is a list of the sub APIs along with a sample use of each API.  See the <a href="http://www.messners.com/gitlab4j-api/javadocs/index.html?org/gitlab4j/api/package-summary.html" target="_top">Javadocs</a> for a complete list of available methods for each sub API.
