+# Steps to reproduce boringssl.patch
+
+## bindgen.rs
+
+Make sure you have the dependencies needed to build
+[bssl-sys](https://boringssl.googlesource.com/boringssl/+/refs/heads/master/rust/bssl-sys/README.md)
+
+```shell
+sudo apt install bindgen
+sudo apt install cmake
+sudo apt install ninja-build
+cargo install cargo-deny
+```
+
+Download boringssl repo and build bssl-sys
+
+```shell
+git clone https://boringssl.googlesource.com/boringssl
+cd boringssl
+cmake -GNinja -B build -DRUST_BINDINGS=x86_64-unknown-linux-gnu
+ninja -C build
+```
+
+This will generate the bindgen.rs file seen in the boringssl.patch file
+
+## rest of files
+
+The rest of the files (3) can just be manually created(bssl-crypto/BUILD, bssl-sys/BUILD) and edited(bssl-sys/src/lib.rs)
+
+The BUILD files will not change (neither will the lib.rs file). The bindgen.rs file may need to be re-generated if the
+boringssl commit in WORKSPACE is updated (ideally we will have upstreamed this patch to boringssl before then
+[b/354710816](b/354710816)).
