 ## Our Pledge
 
-Originally, NeoTerm was designed as the front end of [Termux](https://github.com/termux/termux-app) to provide some functions that Termux didn't have, but we found it very convenient. In continuous development, we discovered our goal: to be the best terminal for Android.
-In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.

 A modern-designed android terminal emulator for the 21st century.
 
 ### Our Pledge
-Originally, NeoTerm was designed as the front end of Termux to provide some functions that Termux didn't have, but we found it very convenient. In continuous development, we discovered our goal: to be the best terminal for Android.
