+
+## Project overview
+APIlite is a lightweight PHP library. A class extends `TPsoft\APIlite\APIlite`, public methods become API actions, requests are processed automatically, and responses are returned as JSON.
+
+The project also generates frontend clients:
+- JavaScript client: `format=javascript` (`.js`)
+- TypeScript client: `format=typescript` (`.ts`, real typed output)
+
+## Core files
+- `src/APIlite.php`: runtime, routing, docs JSON/HTML/client generation
+- `src/help.tpl.php`: HTML documentation template
+- `src/javascript.tpl.php`: JavaScript client template
+- `src/typescript.tpl.php`: TypeScript client template
+- `bin/apilite-files`: helper script for bootstrapping files in consumer projects
+
+## Working rules
+- Keep API behavior backward compatible unless explicitly requested.
+- Maintain both generated clients:
+  - JavaScript stays plain JS.
+  - TypeScript stays typed (interfaces + typed method signatures).
+- If you change output field names in JSON help, update README and templates consistently.
+- Prefer small, focused changes over broad rewrites.
+
+## Verification checklist
+- Run syntax checks on edited PHP files:
+  - `php -l src/APIlite.php`
+  - `php -l src/help.tpl.php`
+  - `php -l src/javascript.tpl.php`
+  - `php -l src/typescript.tpl.php`
+  - `php -l bin/apilite-files`
+- If client generation changes, test with:
+  - `php test/APIcalculator.php --javascript`
+  - `php test/APIcalculator.php --typescript`
+
+## Documentation rule
+When output format names/flags/URLs change, update `README.md` in the same change set.

 A set of tools to simplify the work of creating backend APIs for your frontend projects. Includes tutorials, patterns and practical examples for creating projects based on REST APIs.
 
+## Installation
+
+Download source code and add to your project
+
+```php
+<?php
+require_once __DIR__ . '/APIlite/src/APIlite.php';
+```
+
+or use composer
+
+```bash
+composer require tpsoft/apilite
+```
+
+and add to your project
+
+```php
+<?php
+require __DIR__ . '/vendor/autoload.php';
+
+class YourAPI extends \TPsoft\APIlite\APIlite {
+
+	/**
+	 * My first method for greetings.
+	 *
+	 * @param string $name Your name
+	 * @param int $age Your age
+	 * @return string Greetings
+	 */
+	public function myFirstMethod(string $name, int $age): string
+	{
+		return 'Hi, I`m '.$name.' and I`m '.$age.' years old.';
+	}
+
+}
+```
+
 ## Basic usage
 
 For example, we create an API for calculator. So we create class `APIcalculator` and store in file `test/APIcalculator.php` where we defined each actions for API as public method.
