+=About
+
+I18n backend which allows to store/get the translations from a database using a sequel.
+
+==Install
+
+Simply install it as any other gem:
+
+  gem install i18n_backend_sequel
+
+Or when using bundler, add it got your Gemfile:
+
+  gem i18n_backend_sequel
+
+This should also install the geokit gem.
+
+==Quick Start
+
+Create the table used to store i18n translations:
+
+  create_table :i18n_translations do |t|
+    String :locale, :null => false
+    String :key, :null => false
+    String :value, :text => true
+    String :interpolations, :text => true
+    TrueClass :is_proc, :null => false, :default => false
+    primary_key [:locale, :key]
+  end
+
+Make I18n use it as its backend:
+
+  I18n.backend = I18n::Backend::Sequel.new
+
+If you want sequel to add missing translations to the database prepend this too:
+
+  I18n::Backend::Sequel.send(:include, I18n::Backend::Sequel::Missing)
+
+==Todo
+
+* Source documentation (rdoc)
+* Tests
+
+==Contributing
+
+If you'd like to contribute a feature or bugfix: Thanks! To make sure your
+fix/feature has a high chance of being included, please read the following
+guidelines:
+
+1. Fork the project.
+2. Make your feature addition or bug fix.
+3. Add tests for it. This is important so we don’t break anything in a future version unintentionally.
+4. Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
+5. Send me a pull request. Bonus points for topic branches.
