 A Lua plugin (macro) for Aegisub to output currently editing
 subtitle information to Discord Rich Presence

 ## Installation
+### Windows
 - Place the binary file `discord-rpc.dll` in your Aegisub installation folder.
   - If you use the discouraged 64-bit Aegisub then please take the
     provided `discord-rpc-64.dll` and rename it as `discord-rpc.dll` 
     before placing it in your Aegisub installation folder.
-    (I don't guarantee if it would work in 64-bit Aegisub because I
-    don't use them and I can't test it. Plus, the official website
-    also discouraged the use of 64-bit release due to lack of support
-    for most of its video tools and renderer)

+### Linux (not tested)
+(While I use Linux alongside Windows, I don't have Aegisub compiled/installed
+natively where this would apply, so I can't test it. When running Aegisub on
+Linux using WINE, the instruction for Windows should be used instead of this)
