+
+## 2025-05-01 - 7.2.3 - fix(docs)
+Improve certificate manager documentation with detailed examples and custom implementation guide
+
+- Added usage examples for MemoryCertManager and MongoCertManager

+Update readme documentation: switch installation instructions to pnpm and clarify usage with MongoCertManager and updated SmartAcme options
+
+- Replaced npm/yarn commands with pnpm commands for installation and testing.
+- Added guidance to ensure the project is set up for TypeScript and ECMAScript Modules.
+- Updated usage examples to include initialization of MongoCertManager instead of legacy mongoDescriptor.
+- Revised challenge handlers examples to reference the current API signatures.
+
+## 2025-05-01 - 7.2.1 - fix(smartacme)
+Centralize interest map coordination and remove redundant interestMap from cert managers
+
+- Removed interestMap property and related logic from MemoryCertManager and MongoCertManager

 ### 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.
+The library automatically handles fetching, renewing, and storing your certificates in a MongoDB database specified via a certificate manager. Ensure your MongoDB instance is accessible and properly configured for use with SmartAcme.
 
 ```typescript
-const mongoDescriptor = {
+import { MongoCertManager } from '@push.rocks/smartacme';
+
+const certManager = new MongoCertManager({
   mongoDbUrl: 'mongodb://yourmongoURL',
   mongoDbName: 'yourDbName',
   mongoDbPass: 'yourDbPassword',
-};
+});
+```
+
+SmartAcme uses the `ICertManager` interface for certificate storage. Two built-in implementations are available:
+
+- **MemoryCertManager**
+  - In-memory storage, suitable for testing or ephemeral use.
+  - Import example:
+    ```typescript
+    import { MemoryCertManager } from '@push.rocks/smartacme';
+    const certManager = new MemoryCertManager();
+    ```
+
+- **MongoCertManager**
+  - Persistent storage in MongoDB (collection: `SmartacmeCert`).
+  - Import example:
+    ```typescript
+    import { MongoCertManager } from '@push.rocks/smartacme';
+    const certManager = new MongoCertManager({
+      mongoDbUrl: 'mongodb://yourmongoURL',
+      mongoDbName: 'yourDbName',
+      mongoDbPass: 'yourDbPassword',
+    });
+    ```
+
+#### Custom Certificate Managers
+
+To implement a custom certificate manager, implement the `ICertManager` interface and pass it to `SmartAcme`:
+
+```typescript
+import type { ICertManager, Cert as SmartacmeCert } from '@push.rocks/smartacme';
+import { SmartAcme } from '@push.rocks/smartacme';
+
+class MyCustomCertManager implements ICertManager {
+  async init(): Promise<void> { /* setup storage */ }
+  async get(domainName: string): Promise<SmartacmeCert | null> { /* lookup cert */ }
+  async put(cert: SmartacmeCert): Promise<SmartacmeCert> { /* store cert */ }
+  async delete(domainName: string): Promise<void> { /* remove cert */ }
+  async close?(): Promise<void> { /* optional cleanup */ }
+}
+
+// Use your custom manager:
+const customManager = new MyCustomCertManager();
+const smartAcme = new SmartAcme({
+  accountEmail: 'youremail@example.com',

-# Plan: Move interestMap from certmanager to smartacme core
+# Plan: Add wildcard domain support to SmartAcme
 
 ## Goal
-- Pull the interest coordination mechanism out of the ICertManager implementations and into the SmartAcme class.
+- Enable SmartAcme to accept wildcard domain inputs like `*.domain.com` or `*.sub.example.com` and correctly request and match wildcard certificates.
 
 ## Steps
-1. Remove `interestMap` from `ICertManager` interface (`ts/interfaces/certmanager.ts`) and its import of `InterestMap`.
+1. [x] Extend SmartacmeCertMatcher:
-2. Strip out `interestMap` property, initialization, and usage from `MemoryCertManager` and `MongoCertManager` (`ts/certmanagers/*.ts`).
+   - [x] Update `getCertificateDomainNameByDomainName()` to handle wildcard prefixes:
-3. In `Smartacme` class (`ts/smartacme.classes.smartacme.ts`):
+       - If input starts with `*.` strip the prefix and return the base domain.
-   - Add a private `interestMap: plugins.lik.InterestMap<string, SmartacmeCert>` property.
+       - For example:
-   - Initialize it in the constructor: `this.interestMap = new plugins.lik.InterestMap((domain) => domain);`.
+         - `*.example.com` → `example.com`
-   - Update `getCertificateForDomain()` and any other consumers to reference `this.interestMap` instead of `this.certmanager.interestMap`.
+         - `*.sub.example.com` → `sub.example.com`
-4. Remove any tests or code that reference the old `interestMap` on `ICertManager` (if any).
+         - `*.a.b.example.com` → `a.b.example.com`
-5. Run CI (`pnpm build` and `pnpm test`) and fix any regressions.
+   - [x] Ensure existing logic for non-wildcards remains unchanged.
-
+2. [x] Update `SmartAcme.getCertificateForDomain()`:
-Please review and confirm before we begin the refactor.
+   - [x] Detect wildcard inputs (`domainArg.startsWith('*.')`).
+   - [x] For wildcard cases, enforce DNS-01 challenge only (throw error if handlers don't support DNS-01).
+   - [x] Use the matcher result to request wildcard certificate identifiers (e.g., `value: '*.baseDomain'`).
+3. [x] Update tests:
+   - [x] Add unit tests in `test/test.certmatcher.ts` for wildcard handling:
+       - `*.example.com` → `example.com`
+       - `*.sub.example.com` → `sub.example.com`
+       - `*.a.b.example.com` → `a.b.example.com`
+   - [x] Add integration stub in `test/test.smartacme.ts` for wildcard input in integration mode:
+       - Call `getCertificateForDomain('*.domain.com')` and expect returned cert `domainName` equals `*.domain.com`.
+4. [x] Update documentation (README.md) if needed.
+5. [x] Run CI (`pnpm build` & `pnpm test`) and fix any regressions.
