+# codegen
+
+[codegen.sh](./codegen.sh) use [quicktype] to
+generate json (de)serializing code in libs/runtime/include
+from [runtime-spec].
+
+[quicktype]: https://github.com/glideapps/quicktype
+[runtime-spec]: https://github.com/opencontainers/runtime-spec
+
+The generated code needs to apply a little [patch](./fix.patch) to compile.
+
+You can recreate that patch follow these instructions:
+
+1. Remove old patch
+
+   ```bash
+   rm ./fix.patch
+   ```
+
+2. Run codegen.sh
+
+   ```bash
+   ./codegen.sh
+   ```
+
+3. Run create-patch.sh, it will start a new shell.
+
+   ```bash
+   ./create-patch.sh
+   ```
+
+4. Change the code as your wish and leave `libs/runtime/include.orig` untouched
+
+5. Exit
+
+   ```bash
+   exit
+   ```
