installation error

Hi

1. This is not clear- do i need to add ref to your style-rtl.alpha6.min.css file only, or add it after original bootsrtap file?
2. I get this error when try to compile with angular cli:
   ERROR in .//css-loader?{"sourceMap":false,"importLoaders":1}!.//postcss-loader?{"ident":"postcss"}!.//bootstrap4rtl/public/css/style-rtl.alpha6.min.css
   Module not found: Error: Can't resolve '../fonts/IranianSerifWeb-Regular.woff' in 'C:\Users\HagarR\Documents\Visual Studio 2017\WebSites\WebSite1\node_modules\bootstrap4rtl\public\css'
   @ .//css-loader?{"sourceMap":false,"importLoaders":1}!.//postcss-loader?{"ident":"postcss"}!.//bootstrap4rtl/public/css/style-rtl.alpha6.min.css 6:104-152
   @ .//bootstrap4rtl/public/css/style-rtl.alpha6.min.css
   @ multi .//bootstrap/dist/css/bootstrap.min.css ./~/bootstrap4rtl/public/css/style-rtl.alpha6.min.css ./src/styles.css
3. bootstrap is now beta but your version is alfa?

Thanks guys
