+- Prefix code: `RSF` (ReasonableFramework)
+- Old prefix code `VSPF` (Very Simple PHP Framework)

-## Specifications
- Various types of database connection drivers. e.g, PHP PDO, MySQLi, Legacy MySQL, MySQL over the shell, Oracle(OCI)
- No OOP, Just `RVHM` structure
-  - R is Route. like as `controller`
-  - V is View
-  - H is Helper. like a `import` on Python, Go, NodeJS
-  - M is Model. it implemented with `KV bind`(like as `Map` data structure), Model is optional.
- Controllable shared variables: Minimize abuse of global variables. Inspired by the `scope` of AngularJS, and `SharedPreferences` of Android Framework
- CGI style compatibility prepared for industrial applications: This framework can utilize both the latest object-oriented style and the CGI style required in industrial applications.
+## Specification
+- Database connection (via PDO, MySQLi (MySQL Improved), MySQL Tranditional, MySQL CLI, Oracle(OCI))
+- RVHM Structure: `R` is Route (like as `controller`), `V` is View, `H` is Helper (like as `import` on Python/Go/NodeJS), `M` is Model and implemented with `KV bind`(like as `Map` data structure), Modal is optional.
+- AppJail(WebApp Sandbox): You can use legacy apps without modifying the source code.

-## Comment about PSR standards
-Many people are saying that this project seems to be distant from the [PSR](https://www.php-fig.org/psr/) standards, and that claim is correct.
+## 한국어(Korean)
+- Resonable PHP Framework(이유있는 PHP 프레임워크)는 한국의 웹 개발 환경에 적합한 PHP 프레임워크입니다.
+- 일부 북미, 유럽권 무료 웹 호스팅에서도 안정적인 운영이 가능합니다.
+- Composer를 포함한 별도의 개발 보조 도구, PHP 플러그인, PHP 프레임워크가 사용 불가능한 환경에 적합합니다.
+- 개발 팀원을 대상으로 객체지향(OOP) 교육이 이루어지지 않아도, 그에 준하는 생존주기(Life cycle)를 보장합니다.
+- Resonable PHP Framework는 CSRF, XSS, SQL Injection 보안 조치를 기본적으로 가지고 있습니다.
+- 한국에서 사용되는 각종 CMS와 API와 연동되어 한국 환경에서 사용 빈도가 높은 구현 유형을 작성하는데 적합합니다.
+- RVHM 구조는 MVC 구조와 함께 사용하실 수 있으며, 기존 개발 스킬로도 사용할 수 있도록 더 유연한 구조를 가집니다.

-The coding convention of this project is similar to the CGI style that was widely used in the early 2000s. Moreover, this style is still observed in solutions written in PHP that are sold in markets such as [WordPress](https://wordpress.org/) plugins, [a local-optimized CMS](https://github.com/gnuboard/gnuboard5), or [Codecanyon](https://codecanyon.net/) in 2023.
-
-Although this project hardly uses object-oriented concepts and does not use package managers like Composer much, it still incorporates concepts such as Model, View, Controller, Router, and Helper that are proposed in modern frameworks, and we have made efforts to provide a similar experience as much as possible.
-
-We made efforts to address common security vulnerabilities (XSS, CSRF, SQL injection) in web applications, and included many code snippets that were designed to minimize reliance on specific DBMS or communication drivers.
-
-The specifications that this project offers are still in demand in enterprise environments, so it can be a useful solution if you happen to be in such a situation.
-
-Whenever this project was introduced, I received a lot of questions about PSR, and I also made efforts to find customers who were willing to pay for a PSR version, such as holding conferences for existing customers. However, there is still no good news. Until good news comes, my plan is to mainly maintain this project.
-
-If you want to comply with the PSR standards and your colleagues are also ready to learn them humbly, we recommend that you consider [Codeigniter](https://github.com/bcit-ci/CodeIgniter) (which has a similar structure to this project) or [Silm Framework](https://github.com/slimphp/Slim).

+## English
+- It is stable in free web hosting, or other restrictive shared web hosting.
+- Ideal for environments where separate development aids, including Composer, PHP extensions, and the famous PHP framework are not available.
+- Ensures a life-cycle similar to that of an object-oriented programming (OOP) level without trained developers.
+- The Reasonable PHP Framework has CSRF, XSS, and SQL Injection security protection as defaults.
+- Compatible with various CMS and API used with REST API, it is suitable to create implementation type that is frequently used in various environment.
+- RVHM structure can be used with MVC structure, and has more flexible structure to use as existing development skill.
