-![cf](https://i.imgur.com/7v5ASc8.png) Lab 07: Vanilla HTTP Server
-======
+# HTTP Servers - Lab 07
 
-## Submission Instructions
-  * fork this repository & create a new branch for your work
-  * write all of your code in a directory named `lab-` + `<your name>` **e.g.** `lab-susan`
-  * push to your repository
-  * submit a pull request to this repository
-  * submit a link to your PR in canvas
-  * write a question and observation on canvas
+### Description:
 
-## Learning Objectives  
-* students will be able to identify key qualities of the HTTP protocol
-* students will be able to implement an HTTP server using the node.js `http` module
+This app allows the user to enter text and have that text displayed in the console with an image of a cow.
 
-## Requirements
-#### Configuration  
-<!-- list of files, configurations, tools, etc that are required -->
-Your lab directory must include  
-* `.gitignore`
-* `.eslintrc`
-* `package.json`
-* `README.md`
+### Launch:
 
-#### Feature Tasks  
-* create an HTTP Server using the NodeJS `http` module
-* create a *custom* body parsing module that is used for parsing the body of all **POST** requests
-* for all requests made to `/`, the server should respond with the following:
-  * a header containing `Content-Type: text/plain`
-  * a status code of **200**
-  * a response with the string "hello from my server!"
-* for all **GET** requests made to `/cowsay`, the server should respond with the following:
-  * the query string should have the key value `text=<message>`
-  * the response header should include `Content-Type: text/plain`
-  * if the query `text=messsage` is set, respond with:
-    * a status code of 200
-    * a response body that includes the value returned from `cowsay.say({ text: <querystring text> })`
-  * if the query `text=message` is **not** set, respond with:
-    * status code = 400
-    * a body including the value returned from `cowsay.say({ text: 'bad request' })`
-* for all **POST** requests made to `/cowsay`, the server should respond with the following:
-  * the response header should include `Content-Type: text/plain`
-  * if the JSON `{text: messsage}` is set in the body, respond with:
-    * a status code of 200
-    * a response body including the value returned from `cowsay.say({ text: <querystring text> })`
-  * if the JSON `{text: messsage}` is **not** set in the body, respond with:
-      * a status code of 400
-      * a body including the value returned from `cowsay.say({ text: 'bad request' })`
-
-## Bonus
-* **2pts:** add the ability to change the cowfile - **ex: dragon, sheep, etc** _(note: this should be done through the querystring)_
+Run the command `npm run start` in one terminal window to get the server running. Next open a second terminal window to run the app. Enter the command `http :[port number] text==` followed by the string you wish to print. To make a post to enter the same command about with only one `=`.
