-## Summary of differential expression analysis workflow
-
 We have detailed the various steps in a differential expression analysis workflow, providing theory with example code. To provide a more succinct reference for the code needed to run a DGE analysis, we have summarized the steps in an analysis below:
 
-1. Obtaining gene-level counts from your preprocessing
