-This repository, `grist-core`, is the heart of Grist, and has what you need to run a powerful spreadsheet hosting server. If you wish to view and edit spreadsheets stored locally, another option is to use the [`grist-electron`](https://github.com/gristlabs/grist-electron) desktop app for Linux, Mac, and Windows. And to show Grist spreadsheets on a website without any special back-end support, you can use [`grist-static`](https://github.com/gristlabs/grist-static), a fully in-browser build of Grist.
