Coc.nvim language servers
From wikinotes
COC exposes language servers to vim, you'll need them to perform completion etc.
You can have multiple language-servers running at once on the same language/file (ex: ruby solargraph+sorbet).
Language Servers
Extensions
Language Servers may have a wrapper built for COC. These are called extensions.
You may install them dynamically with
:CocInstall coc-python
and sometimes automatically likePlug 'neoclide/coc-tsserver', {'do': 'yarn install --frozen-lockfile'}
.

Some programs may be able to function as an LSP, and can be registered to do so.
