New to Managing Performance Appraisals at a Startup? Where Should I Begin?

I would request your help with understanding how performance appraisals are processed. I have joined a new startup company, and I need to handle the entire performance appraisal process. How should I start?

Please refer to this post. I have briefly described the appraisal process here. Still, if you have any doubts, please do revert to me.

Hi, I am in the content writing industry and have a small team of 10 writers. I have decided to conduct 2 performance appraisals per year. Their performance appraisal will be based on the number of pages they provide and whether they meet the targets I set for them over the course of 6 months. I aim to make the process transparent, ensuring that they "get paid according to what they contribute." Please advise me on the best way to implement this.
