-## Source Integration
-
-We recommend to use our pre-built `pocketpy.h` in [Github Release](https://github.com/blueloveTH/pocketpy/releases/latest) page.
-To compile it with your project, these flags must be set:
-
-+ `--std=c++17` flag must be set
-+ Exception must be enabled
-+ RTTI is not required
-
-!!!
-You can use `g++`, `cl.exe` or `clang++` to compile your project.
-For maximum performance, we recommend to `clang++` with `-O2` flag.
-`clang++` can produce faster binary than `g++` or `cl.exe`.
