# Introduction # Introduction
RT-Thread was born in 2006, it is an open source, neutral, and community-based real-time operating system (RTOS). RT-Thread was born in 2006, it is an open source, neutral, and community-based real-time operating system (RTOS).
RT-Thread is mainly written in C language, easy to understand and easy to port(can be quickly port to a wide range of mainstream MCUs and module chips). It applies object-oriented programming methods to real-time system design, making the code elegant, structured, modular, and very tailorable.

RT-Thread has Standard version and Nano version. For resource-constrained microcontroller (MCU) systems, the NANO kernel version that requires only 3KB Flash and 1.2KB RAM memory resources can be tailored with easy-to-use tools; And for resource-rich IoT devices, RT-Thread can use the on-line software package management tool, together with system configuration tools, to achieve intuitive and rapid modular cutting, seamlessly import rich software packages, thus achieving complex functions like Android's graphical interface and touch sliding effects, smart voice interaction effects, and so on.

RT-Thread has now been ported for nearly 90 development boards, most BSPs support MDK, IAR development environment and GCC compiler, and have provided default MDK and IAR project, which allows users to add their own application code directly based on the project. Each BSP has a similar directory structure, and most BSPs provide a README.md file, which is a markdown-format file that contains the basic introduction of BSP, and introduces how to simply start using BSP.

Env is a development tool developed by RT-Thread which provides a build environment, text graphical system configuration, and package management capabilities for project based on the RT-Thread operating system. Its built-in `menuconfig` provides an easy-to-use configuration tool. It can tailor the kernels, components and software packages freely, so that the system can be constructed by building blocks.

RT-Thread Studio Demonstration: [User Manual](https://www.rt-thread.io/document/site/rtthread-studio/um/studio-user-manual/) | [Tutorial Videos](https://youtu.be/ucq5eJgZIQg)
![studio](./documentation/figures/studio.gif) RT-Thread Studio IDE (a.k.a. RT-Studio) is a one-stop intergrated development environment built by RT-Thread team. It has a easy-to-use graphical configuration system and a wealth of software packages and components resources. RT-Studio has the features of project creation, configuration and management,as well as code editing, SDK management, build configuration, debugging configuration, program download and debug. We're looking to make the use of RT-Studio as intuitive as possible, reducing the duplication of work and improving the development efficiency.
## Getting Started ![studio](./documentation/figures/studio.gif)
## Env Tool
[Env Manual](https://www.rt-thread.io/document/site/programming-manual/env/env/)
In the early stage, RT-Thread team also created an auxiliary tool called Env. It is an auxiliary tool with a TUI (Text-based user interface). Developers can use Env tool to configure and generate the GCC, Keil MDK, and IAR projects.

RT-Thread BSP can be compiled directly and downloaded to the corresponding development board for use. In addition, RT-Thread also provides qemu-vexpress-a9 BSP, which can be used without hardware platform. See the getting started guide below for details.
