 ### Usability of the downloaded artifact
-The downloaded artifact from [Release/Tag](https://github.com/open-telemetry/opentelemetry-cpp-contrib/releases) or [GitHub Actions](https://github.com/open-telemetry/opentelemetry-cpp-contrib/actions/workflows/webserver.yml) is built on CentOS7. This contains shared libraries for both apache and nginx instrumentation. The shared libraries can be located at ```WebServerModule/Apache``` or ```WebServerModule/Nginx``` for respective webservers. But, the common libraries, related to opentelemetry, are located at ```sdk_lib/lib/``` which are used by both apache and nginx instrumentation.
