-Sequence Generator 
+# Sqlserver::Sequence
+
+[![Gem Version](https://badge.fury.io/rb/sqlserver-sequence.svg)](https://badge.fury.io/rb/sqlserver-sequence)
+
+A Rails plugin for SQL Server sequences.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'sqlserver-sequence'
+```
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install sqlserver-sequence
+
+## Usage
+
+Specify the attribute you'd like to sequence
+
+```ruby
+class Supplier < ActiveRecord::Base
+  sequence :number
+end
+```
+
+Now when you create a record `number` will be assigned the next value for that sequence.
+
+    $ supplier = Supplier.create
+    $ supplier.number
+    > 10 # generated by sequence named 'number'
+
+    $ other_supplier = Supplier.create
+    $ other_supplier.number
+    > 11
+
+You can also define multiple sequences
+
+```ruby
+class Supplier < ActiveRecord::Base
+  sequence :number
+  sequence :purchase_order
+end
+```
+
+### Options
+
+###### name
+
+By default `sqlserver-sequence` will look for a row in `sys.sequences` with the same `name` as the attribute. You can use the `name` option if the sequence is named differently.
+
+```ruby
+class Supplier < ActiveRecord::Base
+  sequence :number, name: 'next_supplier_number'
+end
+```
+    $ supplier = Supplier.create
+    $ supplier.number 
+    > 10 # generated by sequence named 'next_supplier_number'
+
+###### prefix
+
+You can use the `prefix` option to prepend every sequence value with a string.
+
+```ruby
+class Supplier < ActiveRecord::Base
+  sequence :number, prefix: 'S-'
+end
+```
+    $ supplier = Supplier.create
+    $ supplier.number
+    > S-10
+
+###### format
+
+Pass a lambda to the `format` option if you need more control over the assigned sequence value.
+
+```ruby
+class Supplier < ActiveRecord::Base
+  sequence :number, format: lambda { |num| num.rjust(10, 0) }
+end
+```
+    $ supplier = Supplier.create
+    $ supplier.number
+    > 0000000010
+
+## Testing with SQLite
+
+If your test suite uses SQLite you'll need to turn off sequence generation or provide a stub for `next_sequence_value`.
+
+```ruby
+before do
+  allow_any_instance_of(Supplier).to receive(:next_sequence_value).and_return('10')
+end
+```
+
+## Contributing
+
+1. Fork it ( https://github.com/zacharywelch/sqlserver-sequence/fork )
+2. Create your feature branch (`git checkout -b my-new-feature`)
+3. Commit your changes (`git commit -am 'Add some feature'`)
+4. Push to the branch (`git push origin my-new-feature`)
+5. Create a new Pull Request
+
+See the [Running Tests](RUNNING_TESTS.md) guide for details on how to run the test suite on SQL Server.

+# Running Tests
+
+To successfully run the test suite you'll need SQL Server credentials and the ability to create tables and sequences.
+
+When the tests are run a `suppliers` table and sequence named `number` are created for support.
+
+## Getting Started
+
+Copy config.yml.sample as config.yml
+
+    $ cp spec/config.yml.sample spec/config.yml
+
+Then update `config.yml` with the server, database and your credentials.
