+Small modification to [strapi-provider-upload-aws-s3](https://www.npmjs.com/package/strapi-provider-upload-aws-s3) to support an optional baseUrl configuration.
+If `baseUrl` is not specified, it works the same as the official aws-s3 plugin.
+
+Original source is [here](https://github.com/strapi/strapi/tree/master/packages/strapi-provider-upload-aws-s3).
+
+package.json:
+
+```
+{
+  //...
+  "dependencies": {
+    //...
+    "strapi-provider-upload-aws-s3": "npm:@chakrahq/strapi-provider-upload-aws-s3@3.6.5",
+    //...
+  },
+ // ...
+}
+```
+
+config/plugins.js:
+
+```
+module.exports = ({ env }) => {
+  //...
+  upload: {
+    provider: 'aws-s3',
+    providerOptions: {
+      accessKeyId: env('AWS_S3_KEY'),
+      secretAccessKey: env('AWS_S3_SECRET'),
+      region: env('AWS_S3_REGION'),
+      params: {
+        Bucket: env('AWS_S3_BUCKET'),
+      },
+      baseUrl: env('AWS_S3_CDN')
+    },
+  },
+  //...
+};
+```
+
+Note:
+`baseUrl` param should be a full URL without a trailing slash.
+Example: `https://cdn.example.com`
