 ### Mac OSX
 Download and open the DMG file.  Drag buckshot into your applications and launch it from there.  
+NOTE! Recent MacOS versions require you to open the "Applications" folder in Finder and right-click -> Choose "Open", as a ~~gatekeeping~~ security precaution.)
 
 ### Windows
 Download and unzip to the folder where you want it installed.  Simply run the buckshot.exe from there. 
+Note: Windows may warn and require you to "run anyway".
 
 ### Linux (Debian)
-Download and untar, then run the buckshot.sh script.  If you have problems see the README.LINUX file. 
+Download and unzip and run `AppRun`.  If you have problems see the README file. 
 
 # Usage
 
-Once you start the program, just "Open Source Image", select the "Apple ][ Display Mode" you want to convert your image to, and click "Preview", or even better, click the "Live Preview" checkbox to get real-time feedback on your conversion settings.  Once you are satisfied with your conversion settings, click "Save Image File" to save in one of the Apple ][ image formats based on the display mode.  If you want to save that image file directly to a ProDOS volume, that is now supported via the "Save To ProDOS" function!  Then you can load it up in your favorit emulator, or transfer it to real disks/flash storage to view on glorious vintage hardware.

 # Build
-This project is written in C++ using the Qt framework.  It calls out to two external binaries for image conversion ([http://www.appleoldies.ca/bmp2dhr/](b2d)) and ProDOS volume support ([http://www.brutaldeluxe.fr/products/crossdevtools/cadius/](CADIUS)).

-You can build and run the project without it, but it won't be able to generate previews or save to ProDOS volumes without those 3rd-party binaries.  The authors of those projects are not involved with this project, but have graciously encouraged my integration attempts with this software.

 # Disclaimer
 This was largely built as a proof-of-concept, and I tried to put it together quite quickly (the original version was over the course of about a week or two.)  I would never suggest that this is ididiomatic C++ code or Qt code.  I am very results oriented and wrote a lot of this quite procedurally, as I went along adding all my planned features.  Please feel free to fork it and make fixes, clean it up, add in other converters, etc.  I probably won't have much time to tinker with this one from here on out, as I have most of the features I need for my own usage at this point.
