+A very easy to use sitemap generator
+
+## Usage
+
+- Import easy-sitemap
+
+```typescript
+import Sitemap from 'easy-sitemap'
+// or
+const Sitemap = require('easy-sitemap').default
+```
+
+- Initialize it
+
+```typescript
+// Create a new instance
+const sitemap = new Sitemap('https://www.example.com') // initialize using your website base
+
+// if you want to let the library manage the response object the line is this
+const sitemap = new Sitemap('https://www.example.com', {
+	response: res
+})
+
+```
+
+- add you're paths
+
+```typescript
+sitemap.addEntry('/path')
+
+// you can also add optionnal elements
+sitemap.addEntry('/path', {
+	// each one are optionnal and they don't all need to be added
+	changefreq: 'always', // webpage change freq
+	lastmod: new Date('2021-01-20'), // webpage lastmod Date
+	priority: 1 // crawler priority
+})
+```
+
+- finally build it !
+
+```typescript
+// it will return a string containing the whole sitemap
+// if you are letting the library manage the response Object it will return an empty string but the page will render ! 
+const result = sitemap.build()
+```
