-## xPub-aws
+# AWS S3 File Upload
+
+In order to use `xpub-aws` you first need to have a `.env` file containing AWS data in the root folder of the starting point of your applications.
+
+The `.env` file should look like this:
+```bash
+AWS_ACCESS_KEY = exampleKey
+AWS_SECRET_KEY = exampleKey/sads/21
+AWS_REGION = region-name
+AWS_BUCKET = bucket-name
+```
+
+Then, as soon as possible in your app you should add the `dotenv` package:
+```js
+require('dotenv').config()
+```
+
+# `xpub-aws` API
+A list of endpoints that help you upload, download and delete S3 files.\
