## What Is Telescope?
`telescope.nvim` is a highly extendable fuzzy finder over lists. Built on the latest
awesome features from `neovim` core. Telescope is centered around
modularity, allowing for easy customization.

customizations globally or individual per picker.

The default previewers are from now on `vim_buffer_` previewers. They use vim buffers for displaying files
and use tree-sitter or regex for file highlighting.
These previewers are guessing the filetype of the selected file, so there might be cases where it misses,
thus leading to wrong highlights. This is because we can't determine the filetype in the traditional way
(we don't do `bufload`. We read the file async with `vim.loop.fs_` and attach only a highlighter), because we can't
execute autocommands, otherwise the speed of the previewer would slow down considerably.
