+
+This is a cross post to some **dynamic linker studies** that I did in the past
+and hosted on github [>> dynld <<][dynld].
+
+The focus was to understand the **process initialization** and to implement a
+minimal **dynamic linker**, which can run a binary with a single shared library
+dependency. Minimal, because the linker just implements what is required to
+explore the concepts of dynamic linking.
+
+In the repository the studies are structured as:
+- [ch1][dynld-ch1]: introduction to dynamic linking
+- [ch2][dynld-ch2]: exploring initial process state
+- [ch3][dynld-ch3]: create a skeleton for the dynamic linker
+- [ch4][dynld-ch4]: build the final dynamic linker (which can load a binary
+  with a single shared library dependency)
+
+All the experiments target the Linux (x86_64) environment, however going to a
+different ISA, e.g Linux (arm) can be achieved quiet "easily" once the general
+concepts are understood.
