---
--- The Idris 2 language server.
---
--- Plugins for the Idris 2 filetype include
--- [Idris2-Vim](https://github.com/edwinb/idris2-vim) (fewer features, stable) and
--- [Nvim-Idris2](https://github.com/ShinKage/nvim-idris2) (cutting-edge,
--- experimental).
---
--- Idris2-Lsp requires a build of Idris 2 that includes the "Idris 2 API" package.
--- Package managers with known support for this build include the
--- [AUR](https://aur.archlinux.org/packages/idris2/) and
--- [Homebrew](https://formulae.brew.sh/formula/idris2#default).
---
--- If your package manager does not support the Idris 2 API, you will need to build
--- Idris 2 from source. Refer to the
--- [the Idris 2 installation instructions](https://github.com/idris-lang/Idris2/blob/main/INSTALL.md)
--- for details.  Steps 5 and 8 are listed as "optional" in that guide, but they are
--- necessary in order to make the Idris 2 API available.
---
--- You need to install a version of Idris2-Lsp that is compatible with your
--- version of Idris 2. There should be a branch corresponding to every released
--- Idris 2 version after v0.4.0. Use the latest commit on that branch. For example,
--- if you have Idris v0.5.1, you should use the v0.5.1 branch of Idris2-Lsp.
---
--- If your Idris 2 version is newer than the newest Idris2-Lsp branch, use the
--- latest commit on the `master` branch, and set a reminder to check the Idris2-Lsp
--- repo for the release of a compatible versioned branch.
