+# MUSL-libkflow
+
+Since libkflow uses CGO internally, we need to build it with a musl c compiler to 
+satisfy our end goal of producing a single statically linked kprobe binary. 
+Unfortunately, creating static libraries in GO with CGO enabled only works with a
+patched version of Go. 
+
+## Creating a new version of libkflow
+
+This guide assumes that you want to build the latest version of libkflow as it exists
+on the `main` branch of the `libkflow` repository. 
+
+### The Steps
+- Update the `libkflow` submodule to the latest version
+```shell
+git submodule update --remote libkflow
+git add .
+git commit -m "Update libkflow to $LATEST_VERSION"
+```
+- Push the changes to github, and the builder will take care of the rest. 
+- One can find the built libraries in the output of the github action.
