+# Dependency Managagement in Prysm
+
+Prysm is go project with many complicated dependencies, including some c++ based libraries. There
+are two parts to Prysm's dependency management. Go modules and bazel managed dependencies. Be sure 
+to read [Why Bazel?](https://github.com/prysmaticlabs/documentation/issues/138) to fully
+understand the reasoning behind an additional layer of build tooling via Bazel rather than a pure
+"go build" project.
+
+## Go Module support
+
+The Prysm project officially supports go modules with some caveats. 
+
+### Caveat 1: Some c++ libraries are precompiled archives
+
+Given some of Prysm's c++ dependencies have very complicated project structures which make building
+difficult or impossible with "go build" alone. Additionally, building c++ dependencies with certain
+compilers, like clang / LLVM, offer a significant performance improvement. To get around this 
+issue, c++ dependencies have been precompiled as linkable archives. While there isn't necessarily
+anything bad about precompiled archives, these files are a "blackbox" which a 3rd party author
+could have compiled anything for this archive and detecting undesired behavior would be nearly
+impossible. If your risk tolerance is low, always compile everything from source yourself, 
+including complicated c++ dependencies.
+
+*Recommendation: Use go build only for local development and use bazel build for production.*
+
+### Caveat 2: Generated gRPC protobuf libraries
+
+One key advantage of Bazel over vanilla `go build` is that Bazel automatically (re)builds generated
+pb.go files at build time when file changes are present in any protobuf definition file or after
+any updates to the protobuf compiler or other relevant dependencies. Vanilla go users should run
+the following scripts often to ensure their generated files are up to date. Further more, Prysm
+generates SSZ marshal related code based on defined data structures. These generated files must
+also be updated and checked in as frequently.
+
+```bash
+./scripts/update-go-pbs.sh
+./scripts/update-go-ssz.sh
+```
+
+*Recommendation: Use go build only for local development and use bazel build for production.*
+
+### Caveat 3: Compile-time optimizations 
+
+When Prysmatic Labs builds production binaries, they use the "release" configuration of bazel to
+compile with several compiler optimizations and recommended production build configurations.
+Additionally, the release build properly stamps the built binaries to include helpful metadata
+about how and when the binary was built. 
+
+*Recommendation: Use go build only for local development and use bazel build for production.*
+
+```bash
+bazel build //beacon-chain --config=release
+```
+ 
+## Adding / updating dependencies
+
+1. Add your dependency as you would with go modules. I.e. `go get ...`
+1. Run `gazelle update-repos -from_file=go.mod` to update the bazel managed dependencies.
+
+Example:
+
+```bash
+go get github.com/prysmaticlabs/example@v1.2.3
+bazel run //:gazelle -- update-repos -from_file=go.mod
+```
+
+The deps.bzl file should have been updated with the dependency and any transitive dependencies. 
+
+Do NOT add new `go_repository` to the WORKSPACE file. All dependencies should live in deps.bzl.
