+# Summary
+
+The field of metagenomics seeks to understand the genomic and functional diversity of microbial
+communities. Modern metagenomic sequencing pipelines produce unlabelled genomic sequences at an
+unprecedented rate. Processing of these sequences, i.e. contigs, involves labelling the taxonomy of these
+contigs. In recent years, the metagenomics fields has been coalescing around the use of the Genome
+Taxonomy Database  [@GTDB], a phylogenetically informed taxonomy for consistently labelling microbial taxa.
+The Genome Taxonomy Network, `GTNet`, is a neural network capable of classifying metagenomic
+contigs with taxonomic labels from the Genome Taxonomy Database.
+
+# Statement of need
+
+`gtnet` [@gtnet] is a Python package and command-line utility built on top of `GTNet`. The purpose of this software
+is to make the predictive capabilities of the GTNet easily accessible to the meteagenomics community. 
+
+In addition to deploying GTNet, the `gtnet` software seeks to address other outstanding issues in the
+field. Many taxonomic classification tools are still released as source code in tarball formats, require
+installation of third-party software that may no longer be maintained, or use application-specific output formats.
+These issues make existing tools cumbersome and difficult to use. By leveraging the existing Python ecosystem, we 
+seek to make a tool that is easier to use and version for the sake if user-friendliness and reproducibility. 
+
+By releasing easily-installable and user-friendly software capable of generating GTDB taxonomies, we
+hope to lower the technical barrier to wide adoption of standardized taxonomy across the metagenomics field.
