You will need to describe the type of R&D your company is doing.
You will need to complete three sections:

Provide the project name, contact details and confirm the tax year the R&D claim is for.
Provide information about the R&D activity you're doing and if it's eligible for the purposes of the tax loss credit.
You must spend 20% or more of your total labour expenditure on R&D.
You will need to provide a breakdown of the total labour expenditure and R&D labour expenditure.
R&D expenditure is incurred on R&D related goods and services. Certain expenditure is excluded.
