+# Nanopb: Bazel build
+The Bazel build system, is designed to be fast and correct. Nanopb provides a
+set of plugins for the Bazel build system allowing Nanopb to be integrated
+into the build.
+
+## Getting started
+Add the following to your WORKSPACE file.
+``` py
+# WORKSPACE
+git_repository(
+ name = "com_github_nanopb_nanopb",
+ remote = "https://github.com/nanopb/nanopb.git"
+ commit = "<TODO:Enter your desired commit>",
+)
+
+load("@com_github_nanopb_nanopb//extra/bazel:nanopb_deps.bzl", "nanopb_deps")
+
+nanopb_deps()
+
+load("@com_github_nanopb_nanopb//extra/bazel:python_deps.bzl",
+ "nanopb_python_deps")
+
+nanopb_python_deps()
+
+load("@com_github_nanopb_nanopb//extra/bazel:nanopb_workspace.bzl",
+ "nanopb_workspace")
+
+nanopb_workspace()
+```
+
+To use the Nanopb rules with in your build you can use the
+`cc_nanopb_proto_library` which works in a similar way to the native
+`cc_proto_library` rule.
+``` py
+# BUILD.bazel
+load("@com_github_nanopb_nanopb//extra/bazel:nanopb_cc_proto_library.bzl",
+ "nanopb_cc_proto_library")
+
+# Your native proto_library.
+proto_library(
+ name = "descriptor",
+ srcs = [
+ "generator/proto/google/protobuf/descriptor.proto",
+ ],
+)
+
+# Generated library.
+cc_nanopb_proto_library(
+ name = "descriptor_nanopb",
+ protos = [":descriptor"],
+ visibility = ["//visibility:private"],
+)
+
+# Depend directly on the generated code using a cc_library.
+cc_library(
+ name = "uses_generated_descriptors",
+ deps = [":descriptor_nanopb"],
+ hdrs = ["my_header.h"],
+)
+```
