-## Welcome to GitHub Pages
+## Welcome to Mapping Commons
 
-You can use the [editor on GitHub](https://github.com/mapping-commons/mapping-commons.github.io/edit/main/README.md) to maintain and preview the content for your website in Markdown files.
+Mapping Commons pulls together mappings from various sources with the goal of offering them as simple to read, well provenanced TSV files in the [SSSOM format](https://github.com/mapping-commons/SSSOM/blob/master/SSSOM.md). At first, the effort will focus on biomedical ontologies and controlled vocabularies, see for example the [Mouse-Human Ontology Mapping Effort](https://github.com/mapping-commons/mh_mapping_initiative). The initiative was founded early 2021.
 
-Whenever you commit to this repository, GitHub Pages will run [Jekyll](https://jekyllrb.com/) to rebuild the pages in your site, from the content in your Markdown files.
