<p>
OpenDRS is a simple online maintenance tracking/discrepancy reporting application. It allows anyone with a web browser to create,
 view, and search writeups. The look and feel of the OpenDRS pages are easily changed. 
Settings that affect all users can be changed in the Admin Functions menu. User specific settings can be changed in the 
My Profile menu. No browser specific HTML is used in OpenDRS, so it should be useable in any browser, and it has been 
tested using Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, and Microsoft Edge.
</p>
<p>
OpenDRS is highly flexible. Instructions are included in the distribution for creating a user terminal with a Raspberry Pi. OpenDRS can be hosted on a 
centralized server, accessed by networked PCs and/or Raspberry Pi terminals. It can also be hosted directly on a Raspberry Pi
terminal as a non-networked standalone system or in a small network of Raspberry Pi terminals.

<p>Several pieces of Open Source software make OpenDRS possible.
