The TRMNL **web server** hosts a growing directory of [first-party plugins](https://trmnl.com/integrations) and [community plugins](https://trmnl.com/recipes) that are driven by [API endpoints](https://trmnl.com/api-docs) + a [templating engine](https://help.trmnl.com/en/articles/10671186-liquid-101). Our [Framework UI](https://trmnl.com/framework) design system is recommended, but not required, for plugin development.

Customers may disassemble their device and mod their firmware without impacting our [Terms of Service](https://trmnl.com/terms). TRMNL **firmware** supports automatic OTA (over the air) updates to WiFi-connected devices and is [open source](https://github.com/usetrmnl/firmware). Here's how it works: -1. TRMNL device wakes up and requests content from web server every _n_ period\* -2. TRMNL web server generates a 1- or 2-bit PNG image.
