+- README file for Shiva (From AMP phase-2)
+
+This collection of files is from the DARPA Assured micropatching (AMP)
+program. This README provides a basic description of the AMP program
+and the overall manifest and description for each file.
+
+
+---- Assured Micropatching Program
+
+The AMP program is a DARPA effort to develop technologies for advancing
+the state of patching ELF binaries and verifying the stability of the
+patch that has been applied. The AMP program can be found here
+https://www.darpa.mil/program/assured-micropatching
+
+DARPA is releasing these files in the public domain to stimulate further
+research. Their release implies no obligation or desire to support additional
+work in this space. The data is released as-is. DARPA makes no warranties as
+to the correctness, accuracy, or usefulness of the released data. In fact,
+since the data was produced by a research prototype, it is practically guaranteed
+to be imperfect.
+
+
+---- Description of Shiva
+
+Shiva was a phase-2 effort to advance the state of ELF binary patching by
+introducing a custom ELF interpreter for loading and linking ELF relocatable
+objects into the process image at runtime. Shiva aims to make patch development
+a seamless process, fitting right into the existing ELF ABI toolchain of
+compilers and linkers. Shiva supports Linux AArch64 environments.
+
+---- Github location
+
+Shiva's github home is at https://github.com/advanced-microcode-patching/shiva
+
+---- File descriptions
+
+README-AMP.md: This file
+README.md: File describing how to build and use Shiva
+documentation/shiva_final_design.pdf: A document describing the internal design of Shiva
+libcapstone.a: A pre-built static library of the Capstone API
+modules/aarch64_patches/cfs_patch1/core-cpu1: A binary built from NASA cSF github repository to test patching against
+modules/aarch64/amp_challenge10/program_c: An aarch64 binary taken from the beaglebone, as a patch challenge for AMP
+include/capstone: Header files from capstone disassembly API
