+The alignments track will draw sashimi-track style arcs across spliced
+alignments (indicated by N in the CIGAR string). If the reads additionally are
+tagged with XS tags, it will try to draw the arcs using the strand indicated by
+the alignment

+### Insertion and clipping indicators

+The alignments track will also draw a upside-down histogram of insertion and
+soft/hard clipped read counts at all positions, and mark significant positions
+(covering 30% of the reads) with a purple triangle.
