+## How to encrypt or decrypt in bulk
+
+The `encrypt` and `decrypt` functions are accessible in the web browser [DevTools](https://developer.mozilla.org/en-US/docs/Glossary/Developer_Tools) console. For bulk usage, you can open the DevTools console while on the [static-encrypt page](https://static-encrypt.ardis.lu/) and directly call the functions. Examples:
+
+```javascript
+// Encrypting several items
+const contentList = ['Static content 1', 'Static content 2', 'Static content 3', 'Static content 4', 'Static content 5'];
+const encryptedContentList = await Promise.all(contentList.map(v => globalThis.encrypt(v, 'example-password')));
