+Ruby Intro
+=============
+
+This 3-part homework gives some basic practice in Ruby as well as
+getting you accustomed to making testing a regular part of your workflow.
+
+**NOTE: If you are working on a local computer, do not clone this repo to your workspace. Fork it first, then clone your fork.**
+
+
+Learning Goals
+--------------
+After completing this assignment, you will know how to:
+
+* Write simple code that uses basic constructs in the Ruby language, including methods and arguments, conditionals, string and array manipulation, regular expressions, and basic object-oriented programming mechanisms
+* Understand the Ruby project conventions for where code files and test files are located in a project's directory hierarchy
+* Run individual tests or suites of tests using the RSpec unit testing tool
+* Understand the basic syntax of RSpec unit tests
+
+Overview
+--------
+
+**You may find the [Ruby documentation at ruby-doc.org](https://ruby-doc.org) helpful to have on hand.**
+
+The repo for this assigment follows a fairly standard Ruby convention for codebases: the code
+files are stored in `lib/` and the test files are stored in `spec/`.
+(We use the RSpec unit-testing framework; if we were using Ruby's default
+framework, known as `Test::Unit`, the test files would be under
+`test/`.)
+
+**We've placed "starter code" in `lib/ruby_intro.rb`; when you're all done, you
+can submit this single file to the autograder.**
+
+However, you can test each of the 3 parts separately. The files
+`spec/part[123]_spec.rb` contain RSpec tests for each of the three
+parts. For example, to test your answers to Part 1, say `rspec
+spec/part1_spec.rb`. `rspec` with no arguments runs the tests in all
+the files `spec/*_spec.rb`.
+
+* The line numbers in the RSpec error report will
+give you guidance as to which tests failed. (You can check the [RSpec
+documentation](http://rspec.info) to see how the `.rspec` file can be
+used to customize the output format.)
+
+If you are working in Codio, you are ready to move on to the next part. If you are working on a local computer, proceed with the following steps.
+
+| Local computer setup |
+|-----|
+To ensure you have the rspec gem installed you need bundler and can then
+run bundle install like so:
+```sh
+$ gem install bundler
+$ cd assignment
+$ bundle
+```
+When the above completes successfully you'll have RSpec installed and can
+run `rspec` from the command line to test your code.

`Hash` and `Enumerable` as they could help tremendously with these
exercises. :-)

0. Define a method `max_2_sum(array)` which takes an array of integers as an argument and returns the sum of its two largest elements. For an empty array it should return zero. For an array with just one element, it should return that element. Run associated tests via: `$ rspec -e '#max_2_sum' spec/part1_spec.rb`
0. Define a method `sum_to_n?(array, n)` that takes an array of integers and an additional integer, n, as arguments and returns true if any two elements in the array of integers sum to n. `sum_to_n?([], n)` should return false for any value of n, by definition.
