Ask HN: Online Accounting Course

Hi guys I want to start my first software company. Unfortunately I don't know anything about accounting. I want to acquire the most important skills to manage and analyze companies financially and to understand the most important concepts of the accounting language. Can you recommend an online course? I have found the following courses. Are these two courses sufficient to realise my plans?
