+### LayerTraceGenerator ###
+
+Generates layer traces from transaction traces. The tool is a custom
+surface flinger build that mocks out everything else apart from the
+front end logic. Transaction traces are written when the transaction
+is applied, along wth a timestamp and vsync id. The transactions
+are parsed from proto and applied to recreate the layer state. The
+result is then written as a layer trace.
+
+Usage:
+1. build and push to device
+2. run ./layertracegenerator [transaction-trace-path] [output-layers-trace-path]

+# <a name="Layer"></a> Fuzzer for Layer
+
+Layer supports the following parameters:
+1. Display Connection Types (parameter name: `fakeDisplay`)
+2. State Sets (parameter name: `traverseInZOrder`)
+3. State Subsets (parameter name: `prepareCompositionState`)
+4. Disconnect modes (parameter name: `disconnect`)
+5. Data Spaces (parameter name: `setDataspace`)
+
+You can find the possible values in the fuzzer's source code.
+
+#### Steps to run
+1. Build the fuzzer
+```
+  $ mm -j$(nproc) surfaceflinger_layer_fuzzer
+```
+2. Run on device
+```
