It also stores historical \nuptime and latency data in your Val Town SQLite, \nwhich is used to power a status page.\n\n\n## Installation\n\n1. **Remix** this starter template on the top right to get started.\n2. Edit the list of URLs to what you want to monitor in [config.json](./status/code/config.json)\n3. \\[Optional] You can manually run [monitor](./code/monitor) a couple times to populate your status page with data\n4. \\[Optional] By default, the downtime dector emails you. Yon can [configure it here](./code/notify)\n\n## Contributing\n\nPull requests welcome!\n\nThe awkward piece is that if your config.json might conflict with mine.\nNo worries! Just send the PR anyways, and I'll be sure to get my config.json\nback into shape after I merge your PR.\n\n## Caveats\n\nThis downtime monitor is only as good as Val Town's own uptime, which\ncurrently isn't very good (only three 9's).
