+# Fuzzer for libcmd_fuzzer
+
+## Plugin Design Considerations
+The fuzzer plugin for libcmd is designed based on the understanding of the library and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+libcmd supports the following parameters:
+1. In (parameter name: `in`)
+2. Out (parameter name: `out`)
+3. Err (parameter name: `err`)
+4. Run Mode (parameter name: `runMode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `in` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider|
+| `out` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider|
+| `err` | `INT32_MIN` to `INT32_MAX` | Value obtained from FuzzedDataProvider|
+| `runMode` | 1.`RunMode::kStandalone` 2. `RunMode::kLibrary` | Value chosen from valid values using FuzzedDataProvider|
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the cmd module.
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+
+## Build
+
+This describes steps to build cmd_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+ $ mm -j$(nproc) cmd_fuzzer
+```
+#### Steps to run
+To run on device
+```
+ $ adb sync data
+ $ adb shell /data/fuzz/${TARGET_ARCH}/cmd_fuzzer/cmd_fuzzer
+```
+
