+eBPF toy code examples (running in kernel) to familiarize yourself
+with syntax and features:
+
+- BTF defined map examples
+ - bpf_graft.c		-> Demo on altering runtime behaviour
+ - bpf_shared.c 	-> Ingress/egress map sharing example
+ - bpf_map_in_map.c	-> Using map in map example
+
+- legacy struct bpf_elf_map defined map examples
+ - legacy/bpf_shared.c		-> Ingress/egress map sharing example
+ - legacy/bpf_tailcall.c	-> Using tail call chains
+ - legacy/bpf_cyclic.c		-> Simple cycle as tail calls
+ - legacy/bpf_graft.c		-> Demo on altering runtime behaviour
+ - legacy/bpf_map_in_map.c	-> Using map in map example
+
+Note: Users should use new BTF way to defined the maps, the examples
+in legacy folder which is using struct bpf_elf_map defined maps is not
+recommanded.
