+Ensure your project includes the necessary TypeScript configuration and dependencies. You'll need to have TypeScript installed and configured for ECMAScript Modules. If you are new to TypeScript, review its [documentation](https://www.typescriptlang.org/docs/) to get started.
+
+### Creating a SmartAcme Instance
+
+Start by importing the `SmartAcme` class and any built-in handlers you plan to use. For example, to use DNS-01 via Cloudflare:
+
+```typescript
+import { SmartAcme } from '@push.rocks/smartacme';
+import * as cloudflare from '@apiclient.xyz/cloudflare';
+import { Dns01Handler } from '@push.rocks/smartacme/ts/handlers/Dns01Handler.js';
+
+// Create a Cloudflare account client with your API token
+const cfAccount = new cloudflare.CloudflareAccount('YOUR_CF_TOKEN');
+
+// Instantiate SmartAcme with one or more ACME challenge handlers
+const smartAcmeInstance = new SmartAcme({
+  accountEmail: 'youremail@example.com',
+  mongoDescriptor: {
+    mongoDbUrl: 'mongodb://yourmongoURL',
+    mongoDbName: 'yourDbName',
+    mongoDbPass: 'yourDbPassword',
+  },
+  environment: 'integration', // 'production' to request real certificates
+  retryOptions: {},         // optional retry/backoff settings
+  challengeHandlers: [
+    new Dns01Handler(cfAccount),
+    // you can add more handlers, e.g. Http01Webroot
+  ],
+  challengePriority: ['dns-01'], // optional ordering of challenge types
+});
+```
+
+### Initializing SmartAcme
+
+Before proceeding to request certificates, start your SmartAcme instance:
+
+```typescript
+await smartAcmeInstance.start();
+```
+
+### Obtaining a Certificate for a Domain
+
+To obtain a certificate for a specific domain, use the `getCertificateForDomain` method. This function ensures that if a valid certificate is already present, it will be reused; otherwise, a new certificate is obtained:
+
+```typescript
+const myDomain = 'example.com';
+const myCert = await smartAcmeInstance.getCertificateForDomain(myDomain);
+console.log('Certificate:', myCert);
+```
+
+### Automating DNS Challenges
+
+SmartAcme uses pluggable ACME challenge handlers (see built-in handlers below) to automate domain validation. You configure handlers via the `challengeHandlers` array when creating the instance, and SmartAcme will invoke each handler’s `prepare`, optional `verify`, and `cleanup` methods during the ACME order flow.
+
+### Managing Certificates
+
+The library automatically handles fetching, renewing, and storing your certificates in a MongoDB database specified in your configuration. Ensure your MongoDB instance is accessible and properly configured for use with SmartAcme.
+
+```typescript
+const mongoDescriptor = {
+  mongoDbUrl: 'mongodb://yourmongoURL',
+  mongoDbName: 'yourDbName',
+  mongoDbPass: 'yourDbPassword',
+};
+```
+
+### Environmental Considerations
+
+When creating an instance of `SmartAcme`, you can specify an `environment` option. This is particularly useful for testing, as you can use the `integration` environment to avoid hitting rate limits and for testing your setup without issuing real certificates. Switch to `production` when you are ready to obtain actual certificates.
+
+### Complete Example
+
+Below is a complete example demonstrating how to use `@push.rocks/smartacme` to obtain and manage an ACME certificate with Let's Encrypt using a DNS-01 handler:
+
+```typescript
+import { SmartAcme } from '@push.rocks/smartacme';
+import * as cloudflare from '@apiclient.xyz/cloudflare';
+import { Qenv } from '@push.rocks/qenv';
+
+const qenv = new Qenv('./', './.nogit/');
+const cloudflareAccount = new cloudflare.CloudflareAccount(qenv.getEnvVarOnDemand('CF_TOKEN'));
+
+async function main() {
+  const smartAcmeInstance = new SmartAcme({
+    accountEmail: 'youremail@example.com',
+    mongoDescriptor: {
+      mongoDbUrl: qenv.getEnvVarRequired('MONGODB_URL'),
+      mongoDbName: qenv.getEnvVarRequired('MONGODB_DATABASE'),
+      mongoDbPass: qenv.getEnvVarRequired('MONGODB_PASSWORD'),
+    },
+    environment: 'integration',
+    challengeHandlers: [ new Dns01Handler(cloudflareAccount) ],
+  });
+
+  await smartAcmeInstance.start();
+
+  const myDomain = 'example.com';
+  const myCert = await smartAcmeInstance.getCertificateForDomain(myDomain);
+  console.log('Certificate:', myCert);
+
+  await smartAcmeInstance.stop();
+}
+
+ main().catch(console.error);
+ ```
+ 
+ ## Built-in Challenge Handlers
+ 
+ This module includes three out-of-the-box ACME challenge handlers:
+ 
+ - **Dns01Handler**
+   - Uses a Cloudflare account (from `@apiclient.xyz/cloudflare`) and Smartdns client to set and remove DNS TXT records, then wait for propagation.
+   - Import path:
+     ```typescript
+     import { Dns01Handler } from '@push.rocks/smartacme/ts/handlers/Dns01Handler.js';
+     ```
+   - Example:
+     ```typescript
+     import * as cloudflare from '@apiclient.xyz/cloudflare';
+     const cfAccount = new cloudflare.CloudflareAccount('CF_TOKEN');
+     const dnsHandler = new Dns01Handler(cfAccount);
+     ```
+ 
+ - **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 { Http01Webroot } from '@push.rocks/smartacme/ts/handlers/Http01Handler.js';
+     ```
+   - Example:
+     ```typescript
+     const httpHandler = new Http01Webroot({ webroot: '/var/www/html' });
+     ```
+ 
+ - **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.
+ 
+ ## Creating Custom Handlers
+ 
+ To support additional challenge types or custom validation flows, implement the `IChallengeHandler<T>` interface:
+ 
+ ```typescript
+ import type { IChallengeHandler } from '@push.rocks/smartacme/ts/handlers/IChallengeHandler.js';
+ 
+ // Define your custom challenge payload type
+ interface MyChallenge { type: string; /* ... */ }
+ 
+ class MyCustomHandler implements IChallengeHandler<MyChallenge> {
+   getSupportedTypes(): string[] {
+     return ['my-01'];
+   }
+ 
+   // Prepare the challenge (set DNS records, start servers, etc.)
+   async prepare(ch: MyChallenge): Promise<void> {
+     // preparation logic
+   }
+ 
+   // Optional verify step after prepare
+   async verify?(ch: MyChallenge): Promise<void> {
+     // verification logic
+   }
+ 
+   // Cleanup after challenge (remove records, stop servers)
+   async cleanup(ch: MyChallenge): Promise<void> {
+     // cleanup logic
+   }
+ }
+ 
+ // Then register your handler:
+ const customInstance = new SmartAcme({
+   /* other options */, 
+   challengeHandlers: [ new MyCustomHandler() ],
+   challengePriority: ['my-01'],
+ });
+
+In this example, `Qenv` is used to manage environment variables, and `cloudflare` library is used to handle DNS challenges required by Let's Encrypt ACME protocol. The `setChallenge` and `removeChallenge` methods are essential for automating the DNS challenge process, which is a key part of domain validation.
+
+## Additional Details
+
+### Certificate Object
+
+The certificate object obtained from the `getCertificateForDomain` method has the following properties:
+
+- `id`: Unique identifier for the certificate.
+- `domainName`: The domain name for which the certificate is issued.
+- `created`: Timestamp of when the certificate was created.
+- `privateKey`: The private key associated with the certificate.
+- `publicKey`: The public key or certificate itself.
+- `csr`: Certificate Signing Request (CSR) used to obtain the certificate.
+- `validUntil`: Timestamp indicating the expiration date of the certificate.
+
+### Methods Summary
+
+- **start()**: Initializes the SmartAcme instance, sets up the ACME client, and registers the account with Let's Encrypt.
+- **stop()**: Closes the MongoDB connection and performs any necessary cleanup.
+- **getCertificateForDomain(domainArg: string)**: Retrieves or obtains a certificate for the specified domain name. If a valid certificate exists in the database, it is returned. Otherwise, a new certificate is requested and stored.
+- **setChallenge(dnsChallenge: any)**: Automates the process of setting DNS challenge records.
+- **removeChallenge(dnsChallenge: any)**: Automates the process of removing DNS challenge records.
+
+### Handling Domain Matching
+
+The `SmartacmeCertMatcher` class is responsible for matching certificates with the broadest scope for wildcard certificates. The `getCertificateDomainNameByDomainName` method ensures that domains at various levels are correctly matched.
+
+```typescript
+import { SmartacmeCertMatcher } from '@push.rocks/smartacme';
+
+const certMatcher = new SmartacmeCertMatcher();
+const certDomainName = certMatcher.getCertificateDomainNameByDomainName('subdomain.example.com');
+console.log('Certificate Domain Name:', certDomainName); // Output: example.com
+```
+
+### Testing
+
+Automated tests can be added to ensure that the setup and functions work as expected. Using a testing framework such as `tap` and mock services for DNS providers (e.g., Cloudflare), you can simulate the process of obtaining and managing certificates without the need for actual domain ownership.
+
+```typescript
+import { tap, expect } from '@push.rocks/tapbundle';
+import { Qenv } from '@push.rocks/qenv';
+import * as cloudflare from '@apiclient.xyz/cloudflare';
+import * as smartacme from '@push.rocks/smartacme';
+

+const testCloudflare = new cloudflare.CloudflareAccount(testQenv.getEnvVarOnDemand('CF_TOKEN'));

+

+# Plan: Diskless HTTP-01 Handler and Renaming Existing Handler
+
+This plan outlines steps to rename the existing filesystem-based HTTP-01 handler to `Http01Webroot`
+and introduce a new diskless (in-memory) HTTP-01 handler for integration with arbitrary HTTP servers
+(e.g., Express).
+
+## 1. Rename existing handler to Http01Webroot
+- In `ts/handlers/Http01Handler.ts`:
+  - Rename `Http01HandlerOptions` to `Http01WebrootOptions`.
+  - Rename class `Http01Handler` to `Http01Webroot`.
+  - Remove the legacy alias; rename the handler directly.
+  - In `ts/handlers/index.ts`:
+    - Export `Http01Webroot` under its new name.
+    - Remove any `Http01Handler` export.
+    - Update existing tests (e.g., `test.handlers-http01.ts`) to import `Http01Webroot` instead of `Http01Handler`.
+
+## 2. Add new diskless (in-memory) HTTP-01 handler
+- Create `ts/handlers/Http01MemoryHandler.ts`:
+  - Implement `IChallengeHandler<{ token: string; keyAuthorization: string; webPath: string }>`, storing challenges in a private `Map<string, string>`.
+  - `prepare()`: add token→keyAuthorization mapping.
+  - `verify()`: no-op.
+  - `cleanup()`: remove mapping.
+  - Add `handleRequest(req, res, next?)` method:
+    - Parse `/.well-known/acme-challenge/:token` from `req.url`.
+    - If token exists, respond with the key authorization and status 200.
+    - If missing and `next` provided, call `next()`, otherwise respond 404.
+- Export `Http01MemoryHandler` in `ts/handlers/index.ts`.
+
+## 3. Write tests for Http01MemoryHandler
+- Create `test/test.handlers-http01-memory.ts`:
+  - Use `tap` and `expect` to:
+    1. `prepare()` a challenge.
+    2. Invoke `handleRequest()` with a fake `req`/`res` to confirm 200 and correct body.
+    3. `cleanup()` the challenge.
+    4. Confirm `handleRequest()` now yields 404.
+
+## 4. Update documentation
+- Add examples in `readme.md` showing how to use both `Http01Webroot` and the new `Http01MemoryHandler`:
+  - Sample code for Express integration using `handleRequest`.
+
+## 5. Build and test
+- Run `pnpm build` and `pnpm test`, ensuring existing tests are updated for `Http01Webroot` and new tests pass.
+
+Please review and let me know if this plan makes sense before proceeding with implementation.
