+# SortedSet Changelog
+
+## 1.0.3 (2021-02-13)
+
+* Enhancements
+  * Switch back to the original [rbtree](https://rubygems.org/gems/rbtree) gem, which added support for Ruby >=3.0.
+
+## 1.0.2 (2020-12-24)
+
+* Enhancements
+  * Switch to the [rbtree3](https://github.com/kyrylo/rbtree3) gem to support Ruby >=3.0.
+
+## 1.0.1 (2020-12-22)
+
+* Enhancements
+  * Be a no-op library for JRuby, as it has its own version of Set and SortedSet.
+
+## 1.0.0 (2020-12-22)
+
+This is the first release of sorted_set as a gem.  Here lists the changes since the version bundled with Ruby 2.7.
+
+* Breaking Changes
+  * The pure-ruby fallback implementation has been removed.  It now requires an RBTree library to install and run.

+# SortedSet
+
+SortedSet implements a Set whose elements are sorted in ascending
+order (according to the return values of their `<=>` methods) when
+iterating over them.
+
+Every element in SortedSet must be *mutually comparable* to every
+other: comparison with `<=>` must not return nil for any pair of
+elements.  Otherwise ArgumentError will be raised.
+
+Currently this library does nothing for JRuby, as it has its own
+version of Set and SortedSet.
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+```ruby
+gem 'sorted_set'
+```
+
+And then execute:
+
+    $ bundle install
+
+Or install it yourself as:
+
+    $ gem install sorted_set
+
+## Usage
+
+```ruby
+require "sorted_set"
+
+set = SortedSet.new([2, 1, 5, 6, 4, 5, 3, 3, 3])
+ary = []
+
+set.each do |obj|
+  ary << obj
+end
+
+p ary # => [1, 2, 3, 4, 5, 6]
+
+set2 = SortedSet.new([1, 2, "3"])
+set2.each { |obj| } # => raises ArgumentError: comparison of Fixnum with String failed
+```
+
+## Development
+
+After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
