📌 References

• Issue: Closes https://app.clickup.com/t/8697qpqp6

📝 Implementation

• There was a missing type that was generating an error while executing the import files from script.

TSError: ⨯ Unable to compile TypeScript:
src/data/templates/msf/MSFModule1.01.ts:347:21 - error TS2322: Type 'string' is not assignable to type 'never'.

Also I've added some instructions to the readme on how to execute the script.
