+# afl-frida - faster fuzzing of binary-only libraries
+
+## Introduction
+
+afl-frida is an example skeleton file which can easily be used to fuzz
+a closed source library.
+
+It requires less memory and is x5-10 faster than qemu_mode but does not
+provide interesting features like compcov or cmplog.
+
+## How-to
+
+### Modify afl-frida.c
+
+Read and modify afl-frida.c then `make`.
+To adapt afl-frida.c to your needs, read the header of the file and then
+search and edit the `STEP 1`, `STEP 2` and `STEP 3` locations.
+
+### Fuzzing
+
+Example (after modifying afl-frida.c to your needs and compile it):
+```
+LD_LIBRARY_PATH=/path/to/the/target/library afl-fuzz -i in -o out -- ./afl-frida
+```
+(or even remote via afl-network-proxy).
+
+# Speed and stability
+
+The speed is very good, about x12 of fork() qemu_mode.
+However the stability is low. Reason is currently unknown.
