+## Quick start
 
 pyCoverM provides two functions:
-1. `is_bam_sorted` - Verifies if a BAM file is sorted by coordinate.
-2. `get_coverages_from_bam` - Computes average contig coverages from sorted BAM files.
+1. `is_bam_sorted`: Checks if a BAM file is sorted by coordinate and returns `True` if sorted, or `False` otherwise.
+2. `get_coverages_from_bam`: Computes the average contig coverage from sorted BAM files. It returns a tuple where the first element is a list of contig names, and the second is a NumPy array of coverage values.
 
+### Example usage
 
 ```py
 >>> import pycoverm
