+# Executing builtin-functions in Occlum
+
+The example shows how to run teaclave builtin-functions in Occlum.
+
+## Build
+
+1. Clone the teaclave project.
+
+```
+git clone https://github.com/apache/incubator-teaclave.git ./teaclave && cd ./teaclave
+```
+
+2. Edit the config/build.config.toml and add the executable binary as accepted inbound service of scheduler. The following is an example that uses teaclave_execution_service_libos as the name of binary.
+
+```
+scheduler = ["teaclave_execution_service", "teaclave_execution_service_libos"]
+```
+
+Note that the same name should be used in the build.config.toml and enclave_info.toml.
+
+3. Build teaclave project. After building the project, you can find the binary teaclave_execution_service_libos in ${TEACLAVE_BIN_INSTALL_DIR}. Work at teaclave project source directory.
+
+```
+mkdir build && cd build
+cmake ..
+make
+```
+
+4. Build occlum instance. Cmake/scripts/build_occlum_instance.sh is a demo script to build an instance.
Review Comment:
Better highlight file path like `Cmake/scripts/build_occlum_instance.sh`.
