 ## FAQ
 
 - **Why is there a lack of updated versions?** <br>
-Currently, vfox-ruby uses precompiled packages from conda-forge and Homebrew on Linux and macOS. You could open an issue in the [ruby-feedstock](https://github.com/conda-forge/ruby-feedstock/issues) repository to remind the maintainers to provide the latest build. Once the latest version is available, the plugin will be updated soon.
-
-- **Are there any dependencies required to use this plugin?** <br>
-On Windows, vfox-ruby uses standalone 7-ZIP archives provided by [RubyInstaller](https://github.com/oneclick/rubyinstaller2/wiki/faq). On Linux and macOS, installing Ruby requires no dependencies other than the built-in commands. Installing TruffleRuby requires `bash`, `make`, `gcc`, `g++` and `zlib-dev`. For more details, refer to the [dependencies](https://github.com/oracle/truffleruby/blob/master/README.md#Dependencies) section.
