+---
+--- `textLSP` is an LSP server for text spell and grammar checking with various AI tools.
+--- It supports multiple text file formats, such as LaTeX, Org or txt.
+---
+--- For the available text analyzer tools and their configuration, see the [GitHub](https://github.com/hangyav/textLSP) page.
+--- By default, all analyzers are disabled in textLSP, since most of them need special settings.
+--- For quick testing, LanguageTool is enabled in the default `nvim-lspconfig` configuration.
+---
+--- To install run: `pip install textLSP`
+
+---@type vim.lsp.Config
