There are several components:
-**Reference Validator and GLSL/ESSL -> AST Front End.** An OpenGL GLSL and OpenGL|ES GLSL (ESSL) front-end for reference validation and translation of GLSL/ESSL into an internal abstract syntax tree (AST).
+### Reference Validator and GLSL/ESSL -> AST Front End
-Status: Virtually complete, with results carrying similar weight as the specifications.
+An OpenGL GLSL and OpenGL|ES GLSL (ESSL) front-end for reference validation and translation of GLSL/ESSL into an internal abstract syntax tree (AST).
-**HLSL -> AST Front End.** An HLSL front-end for translation of an approximation of HLSL to glslang's AST form.
+**Status**: Virtually complete, with results carrying similar weight as the specifications.
-Status: Partially complete. Semantics are not reference quality and input is not validated.
+### HLSL -> AST Front End

+**Status**: Partially complete. Semantics are not reference quality and input is not validated.
This is in contrast to the [DXC project](https://github.com/Microsoft/DirectXShaderCompiler), which receives a much larger investment and attempts to have definitive/reference-level semantics.
See [issue 362](https://github.com/KhronosGroup/glslang/issues/362) and [issue 701](https://github.com/KhronosGroup/glslang/issues/701) for current status.
-**AST -> SPIR-V Back End.** Translates glslang's AST to the Khronos-specified SPIR-V intermediate language.
+### AST -> SPIR-V Back End
+
+Translates glslang's AST to the Khronos-specified SPIR-V intermediate language.
+
+**Status**: Virtually complete.
+
+### Reflector
+
+An API for getting reflection information from the AST, reflection types/variables/etc. from the HLL source (not the SPIR-V).
+
+**Status**: There is a large amount of functionality present, but no specification/goal to measure completeness against. It is accurate for the input HLL and AST, but only approximate for what would later be emitted for SPIR-V.
-Status: Virtually complete.
+### Standalone Wrapper
-**Standalone Wrapper.** `glslangValidator` is command-line tool for accessing the functionality above.

Status: Complete.
