+# service_template
+
+Template of a C++ service that uses [userver framework](https://github.com/userver-framework/userver).
+
+
+## Download and Build
+
+To create your own userver-based service follow the following steps:
+
+1. Press the green "Use this template button" at the top of this github page
+2. Clone the service `git clone your-service-repo && cd your-service-repo && git submodule update --init`
+3. Give a proper name to your service and replace all the occurences of "service_template" string with that name
+4. Feel free to tweak, adjust or fully rewrite the source code of your service.
+
+
+## Makefile
+
+Makefile contains typicaly useful targets for development:
+
+* `make build-debug` - debug build of the service with all the assertions and sanitizers enabled
+* `make build-release` - release build of the service with LTO
+* `make test-debug` - does a `make build-debug` and runs all the tests on the result
+* `make test-release` - does a `make build-release` and runs all the tests on the result
+* `make service-start-debug` - builds the service in debug mode and starts it
+* `make service-start-release` - builds the service in release mode and starts it
+* `make` or `make all` - builds and runs all the tests in release and debug modes
+* `make format` - autoformat all the C++ and Python sources
+* `make clean-` - cleans the object files
+* `make dist-clean` - clean all, including the CMake cached configurations
+* `make install` - does a `make build-release` and run install in directory set in environment `PREFIX`
+* `make install-debug` - does a `make build-debug` and runs install in directory set in environment `PREFIX`
+* `make docker-COMMAND` - run `make COMMAND` in docker environment
+* `make docker-build-debug` - debug build of the service with all the assertions and sanitizers enabled in docker environment
+* `make docker-test-debug` - does a `make build-debug` and runs all the tests on the result in docker environment
+* `make docker-start-service-release` - does a `make install-release` and runs service in docker environment
+* `make docker-start-service-debug` - does a `make install-debug` and runs service in docker environment
+* `make docker-clean-data` - stop docker containers
+
+Edit `Makefile.local` to change the default configuration and build options.
+
