-## Why Poac?
-
-C++ is often considered a complex language and unconsciously avoided by many.  The absence of a definitive package manager and the unfamiliar syntax of build systems like [CMake](https://cmake.org) make it seem difficult to set up a C++ environment, leaving people hesitant.
-
-To simplify the process and allow users to develop applications and libraries without worrying about [CMake](https://cmake.org), I created a package manager and build system with an intuitive interface, similar to [Cargo](https://github.com/rust-lang/cargo). This allows developers to focus on learning C++ without any hindrances. Additionally, I aim to integrate with other build systems and package managers, providing a seamless transition between development environments.

-### Naming Background
-
-Poac is originated from `cpp` but designed to prioritize ease of typing and reduce strain on one hand as it will be frequently used as a command. Its name is ergonomically optimized to prevent the development of tenosynovitis.

-
-Despite C++ often being overlooked for product development, I believe that Poac can help to promote it as a fun language. Amemiya and Mizutani argue that the sound of `/p/` is associated with a bright and soft impression among Japanese consonants (157)[^1]. In the same way, I believe that Poac's name can convey a similarly positive impression.
