+# OpenTelemetry library builder
+
+**How to use this build script:**
+
+The build script `build.sh` can be used to build OpenTelemetry and
+it's dependencies within the desired base image.
+The final image only contains the necessary files in `/`.
+
+```sh
+bash build.sh -b alpine -j ${nproc} -g v1.43.2 -o v1.3.0 -t 0.14.1
+
+# copy to current dir
+docker create -ti --name otel otel-cpp-<base_image> bash
+docker cp otel:/ ./
+docker rm -f otel
+
+docker create -ti --name grpc grpc-<base_image> bash
+docker cp grpc:/ ./
+docker rm -f grpc
+
+docker create -ti --name thrift thrift-<base_image> bash
+docker cp thrift:/ ./
+docker rm -f thrift
+```
