+# Red Plasma - Plasma Ruby
+
+Red Plasma is the Ruby bindings of Plasma. Red Plasma is based on GObject Introspection.
+
+Plasma is an in-memory object store and cache for big data.
+
+[GObject Introspection](https://wiki.gnome.org/action/show/Projects/GObjectIntrospection) is a middleware for language bindings of C library. GObject Introspection can generate language bindings automatically at runtime.
+
+Red Plasma uses [Plasma GLib](https://github.com/apache/arrow/tree/master/c_glib/plasma-glib) and [gobject-introspection gem](https://rubygems.org/gems/gobject-introspection) to generate Ruby bindings of Plasma.
+
+Plasma GLib is a C wrapper for [Plasma C++](https://github.com/apache/arrow/tree/master/cpp/plasma). GObject Introspection can't use Plasma C++ directly. Plasma GLib is a bridge between Plasma C++ and GObject Introspection.
+
+gobject-introspection gem is a Ruby bindings of GObject Introspection. Red Plasma uses GObject Introspection via gobject-introspection gem.
+
