+# Cowsay HTTP Server
+
+The cowsay module is a fun module for wrapping text.
+
+# How to install
+
+```sh
+git clone https://github.com/geoffsimons/07-vanilla-http-server.git
+npm i
+```
+- To startup the server:
+```sh
+node server.js
+```
+
+# API
+
+This server follows RESTful ideology, with the following routes:
+* GET /
+--Get a greeting as text/plain
+* GET /cowsay?text=Something+to+say[&f=<cow_name>]
+- `text` should be a URL encoded string to wrap
+- `f` is what cow you want to have speak
+* POST /cowsay
+```js
+{
+  text: 'Something to say (REQUIRED)',
+  f: 'beavis.zen'
+}
+```
+See the cowsay docs for more cow names.
