+<h1 align="center">Welcome to Barry Energy API Client 👋</h1>
+<p>
+  <img alt="Version" src="https://img.shields.io/badge/version-1.0.0-blue.svg?cacheSeconds=2592000" />
+  <a href="LICENSE" target="_blank">

+  </a>
+</p>
+
+> Simple python package to work with the API of Barry Energy. 
+> The API documentation can be found [here](https://developer.barry.energy).
+
+> Please be aware that this project is <u>NOT</u> offical.
+
+## Install
+
+```sh
+pip3 install barry-energy-api
+```
+
+## Usage
+
+#### Get your API Token
+```sh
+Get from mobile app under "Add-ons" -> "Barry API"
+```
+<br>
+
+1. Import the package
+```python
+from barry_energy_api import PriceZone, BarryEnergyAPI
+```
+2. Initialize the API
+```python
+api = BarryEnergyAPI('api-token', 5, PriceZone.DK_EAST)
+```
+3. Get aggregated consumption for the last 5 days as defined when API was initialized.
+```python
+api.consumption()
+```
+4. Get prices from the last two days.
+##### Notice that methode has overloading
+```python
+api.spotprices(2)
+```
