I think in the following sentences at the picture, using the verbs `clean`, `create` and `add` are incorrect grammatically. For example in the sentence `Add readme`, the **readme file** has already been added by developer why he has used an imperative sentence?

What i think is correct:

> 
> **Adding readme** or **the readme file has been added** (not `add readme`)
> 
> 
>
