+# [Kinchan](https://itazuranakiss.fandom.com/wiki/Kinnosuke_Ikezawa)
+## Composable browser automation for Ruby.
+
+### Requirements
+
+* Ruby
+* Bundler
+
+### Getting Started
+
+Create a new directory for your Kinchan project
+
+`mkdir kinchan_project && cd kinchan_project`
+
+Create the tasks directory where you'll store your Kinchan tasks
+
+`mkdir tasks`
+
+Initialize bundler
+
+`bundle init`
+
+Add the Kinchan gem to your bundle
+
+`bundle add kinchan`
+
+Now that we've got the structure the rest of the readme will teach you how to create, compose, and run Kinchan tasks 👽 
+
+### Creating a Task
+
+In your tasks directory create a Ruby file with any name
+
+e.g. `touch ruby_reddit.rb`
+
+In your task's Ruby file you'll need to `require 'kinchan'`
+
+and then define your task as a class that inherits from `Kinchan::Task`
+
+so far your file should look a little something like this
+```ruby
+require 'kinchan'
+
+class VisitRubysReddit < Kinchan::Task
+end
+```
+
+All Kinchan tasks require an execute method that takes a single parameter (the selenium browser object) like so
+
+```ruby
+require 'kinchan'
+
+class VisitRubyReddit < Kinchan::Task
+  def execute(browser)
+    browser.navigate.to 'https://old.reddit.com/r/ruby'
+  end
+end
+```
+
+That's all it takes to create a basic task! If we run it we'll see a browser process start and navigate to the Ruby subreddit. For a full description of the 
+browser API check out the [wiki page](https://github.com/SeleniumHQ/selenium/wiki/Ruby-Bindings) for Ruby Selenium (they call it a "driver").
+
+### Running a Task
+
+Create a Ruby file in the root level of your Kinchan project and require your task
+
+Create a new instance of the task and call `run`
+
+e.g.
+
+```ruby
+require_relative 'tasks/ruby_reddit'
+
+VisitRubyReddit.new.run
+```
+
+That's all it takes to run a task. Kinchan handles the rest.
+
+### Passing Data to a Task
+
+A task's initialize function can accept options, just don't forget to call super
+
+e.g.
+
+```ruby
+class Search < Kinchan::Task
+  def initialize(**options)
+    super
+    @query = options[:query]
+  end
+
+  def execute(browser)
+    browser.navigate.to 'https://www.google.com/search?q=#{CGI.escape(@query)}'
+  end
+end
+```
+
+### Composing Tasks
+
+Tasks can call any number of other tasks either before or after they execute, and their dependencies
+will have their dependencies ran and so on
+
+This is done by specifying dependencies with a task's `@before_tasks` or `@after_tasks` in their initialize method
+
+e.g.
+
+```ruby
+class PrintFirstResult < Kinchan::Task
+  def initialize(**options)
+    super
+    @before_tasks << { task: :search, options: options }
+    # specify that the search task should run, with the same options, before running this task
+  end
+
+  def execute(browser)
+    puts browser.execute_script "return document.querySelector('.srg a').innerText"
+  end
+end
+```
+
+Task's do not need to be in the same scope, as long as the task exists Kinchan will find and run it when appropriate
+
+### Setting Selenium Browser Options
+
+before running your task you can modify the selenium browser options like so
+
+```ruby
+Kinchan::Task.browser = :chrome
+Kinchan::Task.browser_options = Selenium::WebDriver::Chrome::Options.new
+Kinchan::Task.browser_options.add_argument('--headless')
+```
