+
 A small, simple and customizable cookie consent bar for use in React applications.
+
+![default look](images/default.png)
+
+## Installation
+
+```
+npm install react-cookie-consent
+```
+
+or use yarn:
+
+```
+yarn add react-cookie-consent
+```
+
+## Using it
+
+You can import the cookie bar like this:
+
+```js
+import CookieConsent from "react-cookie-consent";
+```
+If you want to set/remove cookies yourself you can optionally import Cookie (straight from js-cookie) like this:
+```js
+import CookieConsent, { Cookie } from "react-cookie-consent";
+```
+
+Then you can use the component anywhere in your React app like so:
+
+```js
+<CookieConsent>
+    This website uses cookies to enhance the user experience.
+</CookieConsent>
+```
+You can optionally set some props like this (next chapter will show all props):
+
+```js
+<CookieConsent
+    location="bottom"
+    buttonText="Sure man!!"
+    cookieName="myAwesomeCookieName2"
+    style={{ background: "#2B373B" }}
+    buttonStyle={{ color: "#4e503b", fontSize: "13px" }}
+>
+    This website uses cookies to enhance the user experience.{" "}
+    <span style={{ fontSize: "10px" }}>
+    This bit of text is smaller :O
+    </span>
+</CookieConsent>
+```
+
+On of the props (onAccept) is a function, this function will be called after the user has clicked the accept button. You can provide a function like so:
+
+```js
+<CookieConsent
+    onAccept={() => {alert("yay!")}}
+>
+
+</CookieConsent>
+```
+
+## Props
+| Prop          |               Type               | Default value | Description                                                                                           |
+|---------------|:--------------------------------:|---------------|-------------------------------------------------------------------------------------------------------|
+| location      | String, either "top" or "bottom" | bottom        | Syntactic sugar to easily enable you to place the bar at the top or the bottom of the browser window. |
+| children      |     String or React component    |               | Content to appear inside the bar                                                                      |
+| disableStyles |              boolean             | false         | If enabled the component will have no default style. (you can still supply style through props)       |
+| buttonText    |              string              | I understand  | Text to appear on the button                                                                          |
+| cookieName    |              string              | CookieConsent | Name of the cookie used to track whether the user has agreed.                                         |
+| onAccept      |             function             | () => {}      | Function to be called after the accept button has been clicked.                                       |
+| style         |              Object              |  ![barstyle](images/barStyle.png)             | React styling object for the bar.                                                                     |
+| buttonStyle   |              Object              |   ![buttonStyle](images/buttonStyle.png)              | React styling object for the button.                                                                  |
+
+
+
+## styling it
+
+You can provide styling for both the bar and the button.
+You can do this using the `style` and `buttonStyle` prop, both of these will append / replace the default style of the component.
+
+You can use `disableStyles={true}` to disable any built-in styling.
+
+### Examples
+
+#### changing the bar background to red
+
+```js
+<CookieConsent
+    style={{ background: "red" }}
+>
+</CookieConsent>
+```
+
+#### changing the button font-weight to bold
+```js
+<CookieConsent
+    buttonStyle={{ fontWeight: "bold" }}
+>
+</CookieConsent>
+```
+
+#### rainbows!
+
+![rainbows!](images/rainbow.png)
+
+If you're crazy enough you can even make a rainbow colored bar:
+
+```js
+<CookieConsent
+    buttonText="OMG DOUBLE RAINBOW"
+    cookieName="myAwesomeCookieName2"
+    style={{ background: "linear-gradient(to right, orange , yellow, green, cyan, blue, violet)", textShadow: "2px 2px black" }}
+    buttonStyle={{background: "linear-gradient(to left, orange , yellow, green, cyan, blue, violet)", color:"white", fontWeight: "bolder", textShadow: "2px 2px black"}}
+>
+    This website uses cookies to enhance the user experience.{" "}
+    <span style={{ fontSize: "10px" }}>
+    This bit of text is smaller :O
+    </span>
+</CookieConsent>
+```
