 # About this Cookbook
 
-The IUPAC FAIR Chemistry Cookbook is intended to be an open, collaborative, community focused resource on working with 
-FAIR data in chemistry. This community resource aims to provide a range of practical and re-usable training materials 
-that demonstrate how to manage digital data files and content. Our goal is to get more practical tools & tips in the 
-hands of practicing chemists and others working with digital chemical data, to lower barriers and smooth the adoption 
-of best practices for sharing and reusing FAIR chemical data. The content primarily consists of actionable recipes 
-for a range of tasks to prepare and deposit FAIR machine-enabled chemical data, identify and extract chemically 
-relevant metadata, and compile and validate chemical data files using online tools. 
 
-FAIR data are findable, accessible, interoperable, and reusable for machine processing {cite:p}`Wilkinson2016`. 
-FAIR chemical data need to be machine-readable, and this can be an unfamiliar scenario for many researchers and 
-other stakeholders involved with publishing and managing experimental data. This cookbook aims to support best 
-practices for sharing and reusing chemical data aligned with the technical criteria for FAIR machine-readable 
-data. Practical, interactive tutorials based on common workflows and readily accessible online tools for 
-working with digital content augment broader guidance. 
+The IUPAC FAIR Chemistry Cookbook aims to provide a range of practical and re-usable training materials that demonstrate 
+how to manage digital data files and content. The scope covers protocols that address machine-readable data pertaining 
+to chemicals and techniques for working with data programmatically. Recipes are developed by active community members and 
+target different tasks across a range of possible use cases for handling chemical data. Materials are presented with 
+relevant chemistry examples, point to external content that are of high quality where available, and reference IUPAC 
+and community digital standards where appropriate.
 
-The IUPAC FAIR Chemistry Cookbook is designed to be an evolving resource for the chemistry community. It is 
-supported by the International Union of Pure and Applied Chemistry (IUPAC) as part of the
-WorldFAIR Initiative (see About this project).
+FAIR data are findable, accessible, interoperable, and reusable for machine processing [Wil16]. FAIR chemical data need 
+to be machine-readable, and this can be an unfamiliar scenario for many researchers and other stakeholders involved with 
+publishing and managing experimental data. Students need to learn how to navigate the scale and range of data types and 
+sources becoming available, extract meaning and insight from aggregations of data programmatically, and apply automated 
+approaches to curation, dissemination, and analysis. This cookbook aims to support best practices for sharing and reusing 
+chemical data aligned with the technical criteria for FAIR machine-readable data. Practical, interactive tutorials based 
+on common workflows and readily accessible online tools for working with digital content augment broader guidance on 
+FAIR and data standards. 
+
+This community repository of interactive tutorials provides hands-on experience with a range of digital data sources, 
+tools and workflows pertaining to automated chemical data processing. Digital notebooks with executable code blocks a
+llow users to engage directly with basic cheminformatics functions integral to working with machine-readable data. 
+The cookbook platform can be readily accessed and used through broadly available online infrastructure and recipes are 
+designed to exemplify the FAIR principles for reuse.
