+This package is available on [npm](https://www.npmjs.com/package/@push.rocks/npmextra) and can be installed into your project as a dependency to enhance npm with additional configuration and tool management capabilities.
 
 ## Usage
+`@push.rocks/npmextra` is designed to supplement npm functionalities with enhanced configuration and tool management. It facilitates the management of project configurations and tool setups in a consolidated manner, enabling a smoother workflow and maintenance process. Below are detailed use cases and examples implemented with ESM syntax and TypeScript.
 
-Use TypeScript for best in class instellisense.
+### Initial Setup and Configuration
+To start using `npmextra` in your project, first include it with an import statement:
 
-## Using npmextra for managing toolconfigs
+```typescript
+import { Npmextra } from '@push.rocks/npmextra';
+```
 
-The main purpose of npmextra is to configure different tools using one npmextra.json. This way complex setups avoid additional complexity caused by too many configuration files.
+Instantiate the `Npmextra` class optionally with a custom path to your project's working directory. If no path is provided, the current working directory (`process.cwd()`) is used.
 
-npmextra.json
+```typescript
+const npmExtraInstance = new Npmextra('/path/to/your/project');
+```
+
+### Managing Tool Configurations with `npmextra.json`
+`@push.rocks/npmextra` excels in unifying tool configurations through a single `npmextra.json` file. Instead of scattering configurations across multiple files, `npmextra` enables you to define tool-specific settings within this centralized configuration file, which can then be accessed programmatically.
+
+#### Creating and Utilizing `npmextra.json`
+
+Create a `npmextra.json` in your project root with the following structure:
 
 ```json
 {
-  "sometool": {
-    "defaultKey1": "awesomeValueFromConfig"
+  "toolname": {
+    "setting1": "value1",
+    "setting2": "value2"
   }
 }
 ```
 
-```typescript
-import { Npmextra } from 'npmextra';
+For example, to configure a hypothetical tool named `toolname`, define its settings as shown above.
 
-let myNpmExtra = new Npmextra('my/path/to/cwd'); // cwd argument is optional
-mergedData = myNpmExtra.dataFor('sometool', {
-  // gets merged with whatever is in the configfile
-  defaultKey1: 'defaultValue1', // so this will get overwritten with "awesomeValueFromConfig"
-  defaultKey2: 'defaultValue2', // this one will pass through unaltered
+#### Accessing Configuration in Your Project
+
+With the configuration defined, you can easily access these settings in your TypeScript code as follows:
+
+```typescript
+// Import the npmextra module
+import { Npmextra } from '@push.rocks/npmextra';
+
+// Create an instance pointing at the current directory
+const npmExtraInstance = new Npmextra();
+
+// Retrieve the configuration for 'toolname', merging defaults with any found in npmextra.json
+const toolConfig = npmExtraInstance.dataFor<{ setting1: string, setting2: string }>('toolname', {
+  setting1: 'defaultValue1',
+  setting2: 'defaultValue2'
+});
+
+// toolConfig now contains the merged settings from npmextra.json and provided defaults
+console.log(toolConfig);
+```
+
+### Key-Value Store Management
+`@push.rocks/npmextra` also includes a Key-Value Store (KeyValueStore) functionality enabling persistent storage of key-value pairs between script executions.
+
+#### Setting Up KeyValueStore
+
+To utilize the KeyValueStore, create an instance specifying its scope (e.g., 'userHomeDir') and a unique identity for your application or tool:
+
+```typescript
+import { KeyValueStore } from '@push.rocks/npmextra';
+
+const kvStore = new KeyValueStore<'userHomeDir'>({
+  typeArg: 'userHomeDir', 
+  identityArg: 'myUniqueAppName'
 });
 ```
 
-### Tools that already use the config feature of npmextra
+You can then use the `writeKey`, `readKey`, `writeAll`, and `readAll` methods to manage your store respectively.
 
-- [npmts](https://www.npmjs.com/package/npmts)
-- [npmci](https://www.npmjs.com/package/npmci)
-- [npmdocker](https://www.npmjs.com/package/npmdocker)
+#### Example: Storing and Retrieving Data
 
-## Using the KeyValueStore
+```typescript
+// Write a single key-value pair
+await kvStore.writeKey('username', 'johnDoe');
 
-## Contribution
+// Read a single key
+const username = await kvStore.readKey('username');
+console.log(username); // Outputs: johnDoe
 
-We are always happy for code contributions. If you are not the code contributing type that is ok. Still, maintaining Open Source repositories takes considerable time and thought. If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+// Write multiple key-value pairs
+await kvStore.writeAll({
+  email: 'john@example.com',
+  isAdmin: true
+});
 
-For further information read the linked docs at the top of this readme.
+// Read all key-value pairs
+const allData = await kvStore.readAll();
+console.log(allData); // Outputs the entire store's contents
+```

+### Advanced Key-Value Store Management
+
+In addition to basic read/write operations, `npmextra`’s `KeyValueStore` supports advanced scenarios like mandatory keys and custom file paths.
+
+#### Example: Mandatory Keys and Custom Paths
+
+Consider a scenario where your application requires specific keys to be present in the KeyValueStore. You can define mandatory keys and use a custom path for your store like this:
+
+```typescript
+import { KeyValueStore } from '@push.rocks/npmextra';
+
+interface CustomData {
+  key1: string;
+  key2: number;
+  key3?: boolean;
+}
+
+const kvStore = new KeyValueStore<CustomData>({
+  typeArg: 'custom',
+  identityArg: 'customApp',
+  customPath: '/custom/path/to/store.json',
+  mandatoryKeys: ['key1', 'key2']
+});
+
+// Ensure all mandatory keys are present
+const missingKeys = await kvStore.getMissingMandatoryKeys();
+if (missingKeys.length) {
+  console.log(`Missing mandatory keys: ${missingKeys.join(', ')}`);
+}
+
+// Use the KeyValueStore
+await kvStore.writeKey('key1', 'value1');
+await kvStore.writeKey('key2', 123);
+
+const key1Value = await kvStore.readKey('key1');
+const allData = await kvStore.readAll();
+
+console.log(key1Value); // Outputs: value1
+console.log(allData); // Outputs: { key1: 'value1', key2: 123 }
+```
+
+### Combining AppData and KeyValueStore
+
+The `AppData` class extends the functionality of `KeyValueStore` by integrating environmental variables, specifying additional configurations, and providing a more structured approach to data management.
+
+#### Example: AppData Usage
+
+```typescript
+import { AppData } from '@push.rocks/npmextra';
+
+interface AppSettings {
+  settingA: string;
+  settingB: number;
+  nestedSetting: {
+    innerSetting: boolean;
+  }
+}
+
+const appDataInstance = await AppData.createAndInit<AppSettings>({
+  dirPath: '/custom/path/to/appdata',
+  requiredKeys: ['settingA', 'settingB'],
+  envMapping: {
+    settingA: 'MY_ENV_A',
+    settingB: 'hard:42',
+    nestedSetting: {
+      innerSetting: 'MY_ENV_INNER'
+    }
+  }
+});
+
+const appDataKvStore = await appDataInstance.getKvStore();
+
+// Writing values
+await appDataKvStore.writeKey('settingA', 'exampleValue');
+await appDataKvStore.writeKey('settingB', 100);
+await appDataKvStore.writeKey('nestedSetting', { innerSetting: true });
+
+// Reading values
+const settingA = await appDataKvStore.readKey('settingA');
+const allSettings = await appDataKvStore.readAll();
+
+console.log(settingA); // Outputs: 'exampleValue'
+console.log(allSettings); // Outputs: { settingA: 'exampleValue', settingB: 100, nestedSetting: { innerSetting: true } }
+```
+
+### Error Handling and Debugging
+
+Proper error handling ensures your integrations with `npmextra` are robust and stable. Below are some strategies for error handling and debugging potential issues.
+
+#### Example: Error Handling in KeyValueStore
+
+```typescript
+import { KeyValueStore } from '@push.rocks/npmextra';
+
+const kvStore = new KeyValueStore('userHomeDir', 'errorHandlingApp');
+
+try {
+  await kvStore.writeKey('importantKey', 'importantValue');
+  const value = await kvStore.readKey('importantKey');
+  console.log(value); // Outputs: importantValue
+} catch (error) {
+  console.error('Error managing key-value store:', error);
+}
+```
+
+#### Debugging Configuration Issues in `npmextra.json`
+
+To debug configuration issues, you can utilize conditional logging and checks:
+
+```typescript
+import { Npmextra } from '@push.rocks/npmextra';
+
+const npmExtraInstance = new Npmextra();
+const toolConfig = npmExtraInstance.dataFor('toolname', {
+  configKey1: 'defaultValue1',
+  configKey2: 'defaultValue2'
+});
+
+if (!toolConfig.configKey1) {
+  console.error('configKey1 is missing in npmextra.json');
+}
+
+console.log(toolConfig);
+```
+
+### Integration Tests
+
+Writing tests ensures that your integration with `npmextra` works as expected. Below are examples of integration tests for both `Npmextra` and `KeyValueStore`.
+
+#### Example: Testing `Npmextra` Class
+
+```typescript
+import { expect, tap } from '@push.rocks/tapbundle';
+import { Npmextra } from '@push.rocks/npmextra';
+
+let npmExtraInstance: Npmextra;
+
+tap.test('should create an instance of Npmextra', async () => {
+  npmExtraInstance = new Npmextra();
+  expect(npmExtraInstance).toBeInstanceOf(Npmextra);
+});
+
+tap.test('should load configuration from npmextra.json', async () => {
+  const config = npmExtraInstance.dataFor('toolname', {
+    defaultKey1: 'defaultValue1',
+  });
+  expect(config).toHaveProperty('defaultKey1');
+});
+
+tap.start();
+```
+
+#### Example: Testing `KeyValueStore` Class
+
+```typescript
+import { expect, tap } from '@push.rocks/tapbundle';
+import { KeyValueStore } from '@push.rocks/npmextra';
+
+let kvStore: KeyValueStore<{ key1: string, key2: number }>;
+
+tap.test('should create a KeyValueStore instance', async () => {
+  kvStore = new KeyValueStore({
+    typeArg: 'userHomeDir',
+    identityArg: 'testApp'
+  });
+  expect(kvStore).toBeInstanceOf(KeyValueStore);
+});
+
+tap.test('should write and read back a value', async () => {
+  await kvStore.writeKey('key1', 'value1');
+  const result = await kvStore.readKey('key1');
+  expect(result).toEqual('value1');
+});
+
+tap.test('should write and read back multiple values', async () => {
+  await kvStore.writeAll({ key1: 'updatedValue1', key2: 2 });
+  const result = await kvStore.readAll();
+  expect(result).toEqual({ key1: 'updatedValue1', key2: 2 });
+});
+
+tap.start();
+```
+
