+# Casbin Library for C/C++
+
+![workflow](https://github.com/casbin/casbin-cpp/workflows/ci_meson/badge.svg)
+
+This is a powerful and efficient open-source access control library for C/C++ projects. It provides support for enforcing authorization based on various [access control models](https://en.wikipedia.org/wiki/Computer_security_model).
+
+## Usage
+
+If you want to try it, consider installing the `meson` build system, and `ninja` must also be installed with it. For example, on the fedora platform, run `dnf install meson`.
+
+Then:
+
+```bash
+git clone git@github.com:casbin/casbin-cpp.git
+# or `git clone https://github.com/casbin/casbin-cpp.git`
+cd casbin-cpp
+
+# start build
+meson build
+ninja -C build # -j8
+```
+
+### For Developers
+
+```bash
+# start install
+cd build
+meson install
+```
+
+Now it should be added to your system.
+
+### For Contributors
+
+In addition, the two subcommands `release` and `format` are provided for easy use.
+
+Just run `ninja -C build <subcommand>`.
+
+_**Note:**_
+
+- Since the `format` script relies on `clang-format`, consider installing it.
+- At least make sure that the code is formatted and can be built locally before submission.
