 # README
 
-Mah Bucket is a file library with tagging, which uses Amazon S3 for storage.
+Mah Bucket is a simple file library with search and tagging, which uses Amazon
+S3 for storage.
 
 It has primarily been developed for storing and organising image files, but
 should hopefully be useful (or at least usable) for other file types too.
 
 
-## Ruby version
+## Ruby and Rails versions
 
-  Mah Bucket was developed using Ruby 2.3.1 and 2.3.3, but will very probably
-  work with earlier and later versions too.  If you find a version it won't run
-  with, please let me know (by email, or by providing a patch to this README
-  file).
+Mah Bucket was initially developed using Ruby 2.3.1 and Rails 5.0.1, and is
+currently using Ruby 2.7.1 and Rails 6.0.3 - so it should have a fairly wide
+compatibility range. If you find a version of either that it won't run with,
+please let me know.
 
 
 ## System dependencies
 
+The paperclip gem requires ImageMagick to be installed.
+
+
+## Services
+
+Mah Bucket uses Amazon S3 for file storage, Google OAuth for authentication,
+and was developed using Postgres for data storage - although any database
+supported by ActiveRecord should work.
