+A change detection server that can notify through various services, written in Go  
+Some out-of-the-box highlights:
+
+- Create watches by connecting filters in a DAG
+- A small runtime footprint, a basic instance uses around 20MB of memory
+- Supports Lua scripting to filter/modify/reduce your data any way you want
+- Send notifications through Discord, Matrix, Slack, Telegram and many more services
+- Disable watches on (repeated) failures
+
+A `Watch` in GoWatch is made by connecting `Filters` together:
