 # TimeDuration
 
-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/time_duration`. To experiment with that code, run `bin/console` for an interactive prompt.

 ## Installation
 
 Add this line to your application's Gemfile:
 
 ```ruby
-gem 'time_duration'
+gem 'time-duration'
 ```
 
 And then execute:
 
     $ bundle
 
 Or install it yourself as:
 
-    $ gem install time_duration
+    $ gem install time-duration
 
 ## Usage
 
-TODO: Write usage instructions here
+
+
+### Parser
+
+```ruby
+duration = TimeDuration.parse('1:10')
+duration.to_s # => "1:10"
+
+duration = TimeDuration.parse('1:70')
+duration.to_s # => "2:10"
+```
+
+### Initializer
+
+```ruby
+TimeDuration::Duration.new # => 0:00
+TimeDuration::Duration.new(minutes: 10) # => 0:10
+TimeDuration::Duration.new(hours: 1) # => 1:00
+TimeDuration::Duration.new(hours: 1, minutes: 10) # => 1:10
+```
+
+### Operations
+
+```ruby
+duration = TimeDuration.parse('0:40') + TimeDuration.parse('0:30')
+duration.to_s # => "1:10"
+
+duration = TimeDuration.parse('0:40') - TimeDuration.parse('0:30')
+duration.to_s # => "0:10"
+```
+
+### Comparisons
+
+```ruby
+TimeDuration.parse('0:40') > TimeDuration.parse('0:30') # => true
+
+TimeDuration.parse('0:60') == TimeDuration.parse('1:00') # => true
+```
 
 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
