-# IES-binary-diffing
+# Build instructions for Binary Diffing
+Use normal build for your own usage. The tools here are used to copy how Intel/Silicom compiles their released versions.
 
+## Requirements
+* Docker
+* patience (specific GCC build will take a while)
+
+## Usage
+* `$ ./do-build-as-silicom.sh [commit]`
+  * Creates CentOS 6.10 container with GCC 4.4.2-7 on it, and builds IES from commit (default _master_). Re-run to build new changes.
+  * Alternatively you can build via GCC 4.4.4-10, but it has slight differences. Do this via `$ GCC_VERSION=4.4.4-10.el6 ./do-build-as-silicom.sh`
+* `$ ./do-binary-diff.sh`
+  * Creates elf_diff container, and diffs produced build on first step. Grabs known Silicom _.so_
+* Outputs for both steps exist under `./output` folder.
