+# @dzeio/logger
+
+A Better logger for your test
+
+## Install
+
+For the browser via `unpkg` use it from Unpkg or download the file locally
+
+```html
+<script src="https://unpkg.com/@dzeio/logger/dist/browser.js"></script>
+<script>
+// Two Elements are available
+var logger = new Logger('prefix') // To initialize a new Logger
+// or
+initConsole() // this will repace the default console by the logger
+</script>
+```
+
+Via Yarn/NPM
+
+```bash
+yarn add @dzeio/logger
+# or
+npm i @dzeio/logger
+```
+
+## Usage
+
+As the Logger Implements the `console` the usage don't vary on their function BUT you have more control
+
+ex:
+
+```js
+import Logger from '@dzeio/logger' // Import the class
+const logger = new Logger('prefix') // initialize it
+// or
+import { logger } from '@dzeio/logger' // Import already initialized one
+
+// You can block Logging for some time
+Logger.isBlocked(true) // false to unblock
+```
