+# REminiscence for AmigaOS 4.1 FE
+
+REminiscence is a re-implementation of the engine used in the game Flashback
+made by Delphine Software and released in 1992. It is developed
+by Gregory Montoir and you can find it on GitHub at 
+https://github.com/cyxx/REminiscence
+
+The icon is based on cedry2kio work as found at
+https://www.deviantart.com/cedry2kio/art/Flashback-Icon-1-404447315
+
+## Installation
+
+Extract the archive wherever you want. In the REminiscence there is the
+*data* folder where you need to copy the data files for the game. The
+*saves* folder is where tha saves files will be stored. 
+
+Please read the README.txt file for more information about where to
+find the data files.
