+# Greeting and Arithmetic
 
-## Submission Instructions
-  * work in a fork of this repository
-  * work in a branch on your fork
-  * write all of your code in a directory named `lab-` + `<your name>` **e.g.** `lab-susan`
-  * submit a pull request to this repository
-  * submit a link to your pull request on canvas
-  * submit a question, observation, and how long you spent on canvas  
+There are two applications in this code, an applications that returns hello to any name entered, and an application that accomplishes some basic arithmetic (added or subtracting two numbers).
 
-## Resources  
-* [node assert docs](https://nodejs.org/dist/latest-v4.x/docs/api/assert.html)
-* [mocha docs](http://mochajs.org/#getting-started)
+# how to run the hello application
+  -open your node.js repl
+  -run module.exports(your-name-goes-here)
+  -talk to your computer in excitement
 
-## Requirements
-
-#### Configuration  
-<!-- list of files, configurations, tools, etc that are required -->
-* include the following:
-  * **README.md** - contains documentation about your lab
-  * **.gitignore** - contains a robust `.gitignore` file
-  * **.eslintrc** - contains the provided `.eslintrc` file
-  * **.eslintignore** - contains the provided `.eslintignore` file
-  * **lib/** - should contain your modules
-  * **test/** - should contain your unit tests
-
-#### Feature Tasks  
-* create a node.js module (`greet.js`) that exports a single function
-  * the `greet` function should have a single parameter that should expect a string as it's input
-  * the `greet` function should return the input name, concatenated with "hello <name>"
-  * the `greet` function should return `null` if the input is not a string
-* create a node.js module named `arithmetic.js`
-  * this module should have `add` and `sub` methods
-  * the `add` method should contain 2 parameters
-    * these parameters should be numbers and the method should return the sum of the 2 numbers
-  * the `sub` method should contain 2 parameters
-    * these parameters should be numbers and the method should return the first number minus the second number
-* decide on the expected behavior for non-number inputs
-
-#### Testing  
-* write a test the expects the greet module to return "hello world!"
-  * this should happen when invoked with "world!" as a parameter
-* write a test for the `add` and `subtract` methods on the arithmetic module
-  * this should ensure that your functions work with number inputs
-
-####  Documentation  
-* write a description of your project (this should be in your `README.md` file)
-
-###### BONUS 1pt
-* write a test that expects the greet module to return null when you use non string values
-* write a test that ensures the functions work as expected with non number inputs
-
-## Rubric  
-* 2pts configuration
-* 3pts feature tasks
-* 3pts tests
-* 2pts documentation
