## Notes

Crow is a C++ microframework for HTTP and WebSocket web services. The project ships as one header file, `crow_all.h`, or as headers that CMake builds, and the setup pages require a recent C++ compiler and Asio development headers. Templates use Mustache.

The systemd guide describes giving a Crow application a systemd service unit, so the application runs as a long-lived process that the system starts.

## Worth knowing

The repository's LICENSE file says BSD 3-Clause, while the documentation page carries MIT permission text without naming a license, so the record uses the BSD 3-Clause statement only. GitHub lists a prerelease newer than the latest stable release.
