+Neovim does not currently include built-in snippets. `vscode-json-language-server` only provides completions when snippet support is enabled. 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
+
+require'lspconfig'.jsonls.setup {
+  capabilities = capabilities,
+}
+```
