 With such a fast-moving field, it can be difficult to know where to start, and this is true both for incoming students planning their first research projects and for established metagenomics researchers looking to pivot to ancient DNA.
 To help orient new people to the field, we have developed an online course and companion textbook that serves as a broad theoretical and practical introduction to the field of ancient metagenomics.
-The textbook is divided into five theoretical chapters and XX practical exercise modules.
+The textbook is divided into five theoretical chapters and 12 practical exercise modules.
 The goal of the theoretical chapters is to provide an introduction to key concepts in genetics and genomics, ancient DNA, metagenomics and ecology, taxonomy and phylogeny, and functional genomics in order to establish the foundational knowledge necessary to plan and carry out ancient metagenomics research.
 The goal of the practical modules is to equip readers with a software toolkit and a practical understanding of the strategies used to analyse ancient metagenomics datasets.

 Focusing on host-associated ancient metagenomics, readers will learn the main steps of ancient metagenomic bioinformatic workflows, become familiar with the command line, learn how to process next-generation-sequencing (NGS) data, conduct taxonomic profiling of datasets, carry out ecological analyses, and perform de novo metagenomic assembly.
-By the end of the textbook, readers will have an understanding of how to effectively carry out the major bioinformatic components of an ancient metagenomic project in an open, reliable, and reproducible manner.
