-7. Run `ng deploy` to deploy your application to Amazon S3.
+7. To apply properties on uploaded files, use the `NG_DEPLOY_AWS_GLOB_FILE_UPLOAD_PARAMS_LIST` variable or the target option `globFileUploadParamsList` as shown below.  
+   We use an array of objects to represent the different configurations.  
+   Each config object needs a `glob` property to define on which files the params will be set.  
+   Other properties on the config object are the params to apply.
+   For informations about the possible params (ACL, Bucket, CacheControl, etc), checkout the documentation of the `s3.upload` method (https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#upload-property)
+
+```json
+"deploy": {
+  "builder": "@jefiozie/ngx-aws-deploy:deploy",
+  "options": {
+    "globFileUploadParamsList": [
+      {
+        "glob": "*",
+        "ACL": "public-read",
+        "CacheControl": "max-age=3600"
+      },
+      {
+        "glob": "*.html",
+        "CacheControl": "max-age=300"
+      }
+    ]
+  }
+},
+```
+
+The order of the config objects matters, the one that comes last is the one that will be used, as shown above:
+
+- CacheControl is set for all files but it's overidden by the next config object only for html files. Convenient for declaring exceptions and not repeat global settings.
+
+To set this using the environment variable `NG_DEPLOY_AWS_GLOB_FILE_UPLOAD_PARAMS_LIST`, simply stringify the config object to JSON with `JSON.stringify`.
+
+```bash
+npx cross-env ... NG_DEPLOY_AWS_GLOB_FILE_UPLOAD_PARAMS_LIST='[{"glob":"*","ACL":"public-read","CacheControl":"max-age=3600"},{"glob":"*.html","CacheControl":"max-age=300"}]' ... ng deploy
+```
+
+8. Run `ng deploy` to deploy your application to Amazon S3.
