 When I switched to macOS, I missed [Irfanview](https://www.irfanview.com) from Windows. I wanted a Mac app to quickly go through images in a folder by hitting left and right arrow keys, and also be able to copy the images to paste in another folder or in a document.
 
 Thinking about it, it seemed like a pretty simple app to make and a great opportunity to dip my toes in Swift and Swift UI, so I did!
 
-- Simple and fast
+# Features
+
+- Simple and fast (mostly thanks to Swift UI)
 - Navigate images in a folder by hitting left/right arrow
-- Remember image from last session (optional)
-- Copy image (useful for pasting in another folder or into a document) or image path (useful for pasting the path in a Terminal)
-- Trash and Delete files
+- Copy image as...
+	- ...an image (⌘C): Useful for pasting in a Finder window or into a Document
+	- ...a file path (⌥⌘C): useful for pasting into a Terminal window
+- Can show some basic information (filename, resolution, filesize) about image
+- Trash (⌫) or Delete (⌥⌘⌫) files
 - Multiple ways to open images:
-	- Drag n drop onto window
+	- Drag n drop into window
 	- Drag n drop onto icon
 	- File > Open... menu
 	- Right click image > Open With
-- Filename, position in folder and resolution shown in title bar (customizable)

 # Download
 
 - Download from the [Releases](https://github.com/lambdan/imageviewer5/releases) page
 - Minimum macOS version is 11.0
+- Because I am not a registered developer your Mac will probably scream at you when you try to open it
+	- Feel free to compile/build it yourself to avoid this
+
+# Known Issues
+
+See the [Issues](https://github.com/lambdan/imageviewer5/issues) page. Most annoying issue right now is probably that GIF images are displayed, but not animated ([#5](https://github.com/lambdan/imageviewer5/issues/5)).
