+--- vscode-json-language-server, a language server for JSON and JSON schema
+---
+--- `vscode-json-language-server` can be installed via `npm`:
+--- ```sh
+--- npm i -g vscode-langservers-extracted
+--- ```
+---
+--- `vscode-json-language-server` only provides completions when snippet support is enabled. If you use Neovim older than v0.10 you need to enable completion, install a snippet plugin and add the following override to your language client capabilities during setup.
+---
+--- ```lua
+--- --Enable (broadcasting) snippet capability for completion
+--- local capabilities = vim.lsp.protocol.make_client_capabilities()
+--- capabilities.textDocument.completion.completionItem.snippetSupport = true
+---
+--- vim.lsp.config('jsonls', {
+---   capabilities = capabilities,
+--- })
+--- ```
+
+---@type vim.lsp.Config
+return {
+  cmd = { 'vscode-json-language-server', '--stdio' },
