- - **Http01Handler**
+ - **Http01Webroot**
    - Writes ACME HTTP-01 challenge files under a file-system webroot (`/.well-known/acme-challenge/`), and removes them on cleanup.
    - Import path:
      ```typescript
-     import { Http01Handler } from '@push.rocks/smartacme/ts/handlers/Http01Handler.js';
+     import { Http01Webroot } from '@push.rocks/smartacme/ts/handlers/Http01Handler.js';
      ```
    - Example:
      ```typescript
-     const httpHandler = new Http01Handler({ webroot: '/var/www/html' });
+     const httpHandler = new Http01Webroot({ webroot: '/var/www/html' });
      ```
  
- Both handlers implement the `IChallengeHandler<T>` interface and can be combined in the `challengeHandlers` array.
+ - **Http01MemoryHandler**
+   - In-memory HTTP-01 challenge handler that stores and serves ACME tokens without disk I/O.
+   - Import path:
+     ```typescript
+     import { Http01MemoryHandler } from '@push.rocks/smartacme/ts/handlers/Http01MemoryHandler.js';
+     ```
+   - Example (Express integration):
+     ```typescript
+     import { Http01MemoryHandler } from '@push.rocks/smartacme/ts/handlers/Http01MemoryHandler.js';
+     const memoryHandler = new Http01MemoryHandler();
+     app.use((req, res, next) => memoryHandler.handleRequest(req, res, next));
+     ```
+  
+ All handlers implement the `IChallengeHandler<T>` interface and can be combined in the `challengeHandlers` array.
