 This library provides tools and plugins for building UI libraries.
 
-## Why you should use this library?
+## Why you should use this library build tool?
 There are few thing to consider when building UI library:
 - Components must be tree-shakable (both JS and CSS).
 - Components must be optimized for SSR.
 - Library must provide Nuxt support.
-- Web components (*)
+- It must be easy and fast to build as UI library for Vuejs.
+- Generates correct `exports` in `package.json`, so library works within any bundler and components are tree-shakable
+
+Library produces builds:
+- cjs - for node (SSR like vite-ssr)
+- iife - for browsers
+- es - for bundlers (like Vite)
+- esm-node - for bundlers, but without vue and css plugins (pure Rollup)
+- nuxt - nuxt module for nuxt3
+- web-components - ES build optimized to be used as web-components (not ready for production usage yet)
+- types - ts types
+- styles - compiled css styles
+
+## Usage
+As a CLI:
+```bash
+  library-build
+```
+Arguments:
+- entry - path to main.ts file. Default `./src/main.ts`
+- nuxtDir - path to nuxt folder where `module.ts` and `runtime` folder are stored. Default: entry file dir + `./nuxt`
+- outDir - path where to put output files. Default `./dist`
+
+As a library: (not ready yet)
 
 ## Recommended project structure
 
-- src
-  - components
-    - [component-name]
-      - [component-name].vue
-  - composables
-  - nuxt (can be changed with nuxtDir argument)
-    - runtime
-      - plugin.ts
-    module.ts
-  - utils
+- 📁 src
+  - 📁 components
