+## Your first request
+
+The following code snippet is the most basic one you can use to get some content from Contentful with this SDK:
+
+```js
+var contentful = require('contentful')
+var client = contentful.createClient({
+  // This is the space ID. A space is like a project folder in Contentful terms
+  space: 'developer_bookshelf',
+  // This is the access token for this space. Normally you get both ID and the token in the Contentful web app
+  accessToken: '0b7f6x59a0'
+})
+// This API call will request an entry with the specified ID from the space defined at the top, using a space-specific access token.
+client.getEntry('5PeGS2SoZGSa4GuiQsigQu')
+.then((entry) => console.log(entry))
+```
+
+You can try and change the above example at [Tonic](https://tonicdev.com/npm/contentful), or if you'd prefer a more Browser oriented example, check out this [JSFiddle](https://jsfiddle.net/contentful/kefaj4s8/) version of our Product Catalogue demo app.
