 # Seed (WIP)
 
 ## a mini MVVM framework
 
 
-- 6kb gzipped!
 
+- 7kb gzipped, no dependency.
 
 - DOM based templates with precise and efficient manipulation
 
 - POJSO (Plain Old JavaScript Objects) Models FTW - even nested objects.
 
+- Logic-less templating which enforces separation of concerns.
 
 - Auto dependency extraction for computed properties.
 
-- computed properties with dynamic context
 
+- Computed properties can have dynamic context.
 
 - Auto event delegation on repeated items.
 
 - [Component](https://github.com/component/component) based, can be used as a CommonJS module but can also be used alone.

 - ability to register a ViewModel so it can be auto-compiled as a nested vm
 
-- literals, function arguments, simple logic comparisons
 
 - let user specify which keys are data/state (i.e. available in $dump())
 
 - tests
 
 - docs
 
-- validation as filter, e.g. sd-value="email | validate email"
 
-- sd-with
 
-- standarized way to reuse components (sd-component?)
 
-- plugins: seed-touch, seed-storage, seed-router

+    - seed-router (express style)
 
+    - sd-validation (e.g. sd-validate="type:email, max:100, required:true")
