See also the [example](example/) subdirectory. But since that example is
*inside* this repostory, it doesn't use and `add_subdirectory` directive.
+### Using Bazel
+A Bazel-based project can use the headers without installing, as follows:
+
+1. Add a `local_repository` to your `WORKSPACE` file. For example:
+```
+local_repository(
+ name = "spirv_headers",
+ path = "external/spirv-headers",
+)
+```
+
+2. Add one of the following to the `deps` of your build target based on your
+needs:
+```
+@spirv_headers//:spirv_c_headers
+@spirv_headers//:spirv_cpp_headers
+@spirv_headers//:spirv_cpp11_headers
+```
+
+For example:
+
+```
+cc_library(
+ name = "project",
+ srcs = [
+ # Path to project sources
+ ],
+ hdrs = [
+ # Path to project headers
+ ],
+ deps = [
+ "@spirv_tools//:spirv_c_headers",
+ # Other dependencies,
+ ],
+)
+```
+
+3. In your C or C++ source code use `#include` directives that explicitly mention
+ the `spirv` path component.
+```
+#include "spirv/unified1/GLSL.std.450.h"
+#include "spirv/unified1/OpenCL.std.h"
+#include "spirv/unified1/spirv.hpp"
+```
+
## Generating the headers from the JSON grammar
This will generally be done by Khronos, for a change to the JSON grammar.
