+```bash
+docker run -ti ghcr.io/aixcc-finals/base-runner <command> <args>
+```
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `reproduce <fuzzer_name> <fuzzer_options>` | build all fuzz targets and run specified one with testcase `/testcase` and given options.
+| `run_fuzzer <fuzzer_name> <fuzzer_options>` | runs specified fuzzer combining options with `.options` file |
+| `test_all.py` | runs every binary in `/out` as a fuzzer for a while to ensure it works. |
+| `coverage <fuzzer_name>` | generate a coverage report for the given fuzzer. |
+
+# Examples
+
+- *Reproduce using latest OSS-Fuzz build:*
+
+<pre>
+docker run --rm -ti -v <b><i>&lt;testcase_path&gt;</i></b>:/testcase gcr.io/oss-fuzz/<b><i>$PROJECT_NAME</i></b> reproduce <b><i>&lt;fuzzer_name&gt;</i></b>
+</pre>
+
+- *Reproduce using local source checkout:*
+
+<pre>
+docker run --rm -ti -v <b><i>&lt;source_path&gt;</i></b>:/src/<b><i>$PROJECT_NAME</i></b> \
