+## Download Nightly Software Build
+The [nightly](https://github.com/DSheirer/sdrtrunk/releases/tag/nightly) release contains current builds of the software 
+for all supported operating systems.  This version of the software may contain bugs and may not run correctly.  However, 
+it let's you preview the most recent changes and fixes before the next software release.  **Always backup your 
+playlist(s) before you use the nightly builds.**  Note: the nightly release is updated each time code changes are 
+committed to the code base, so it's not really 'nightly' as much as it is 'current'.

 ## Minimum System Requirements
 * **Operating System:** Windows (~~32 or~~ 64-bit), Linux (~~32 or~~ 64-bit) or Mac/Linux (64-bit, 10.14 or higher)
