-### Component Name
-
-If you don't specified the component name with [name](https://vuejs.org/v2/api/#name) component option, by default, it's named based on your `*.vue` filename (no `.vue` extention).
-
 ### Syntax Highlighting
 
 Currently there is syntax highlighting support for [Sublime Text](https://github.com/vuejs/vue-syntax-highlight), [Atom](https://atom.io/packages/language-vue), [Vim](https://github.com/posva/vim-vue), [Visual Studio Code](https://marketplace.visualstudio.com/items/liuji-jim.vue), [Brackets](https://github.com/pandao/brackets-vue), and [JetBrains products](https://plugins.jetbrains.com/plugin/8057) (WebStorm, PhpStorm, etc). Contributions for other editors/IDEs are highly appreciated! If you are not using any pre-processors in Vue components, you can also get by treating `*.vue` files as HTML in your editor.
