+# How To Extend Initial ArkTS Corpus
+
+This corpus is generated from ArkTS API examples: <https://gitee.com/openharmony/docs/tree/master/en/application-dev/reference/apis-arkts>
+
+In order to extend the corpus please follow the steps:
+
+1. Convert the given TypeScript code with the help from <https://www.typescriptlang.org/> playground. Use import line so the compiler understands that you are using the API extension and is able to produce JavaScript code.
+2. Create a new `.js` file with this code in `InitialArkTSCorpus` folder.
+3. Compile the given file to create corresponding `.fzil` program file (serialized `Program` class representation of FuzzIL program): `swift run FuzzILTool --compile ./InitialArkTSCorpus/<yourJSFile>.js`
+4. Run fuzzing with importing of the initial ArkTS corpus. Provide the following options to FuzzilliCli: `--importCorpus=./InitialArkTSCorpus --corpusImportMode=full`
+
+The full mode means you do not need to either assess or minimize the provided programs. They will be fed to mutators as is.
