+-- An integrated language service for Typst [taɪpst]. You can also call it "微霭" [wēi ǎi] in Chinese.
+--
+-- Currently some of Tinymist's workspace commands are supported, namely:
+-- `LspTinymistExportSvg`, `LspTinymistExportPng`, `LspTinymistExportPdf
+-- `LspTinymistExportMarkdown`, `LspTinymistExportText`, `LspTinymistExportQuery`,
+-- `LspTinymistExportAnsiHighlight`, `LspTinymistGetServerInfo`,
+-- `LspTinymistGetDocumentTrace`, `LspTinymistGetWorkspaceLabels`, and
+-- `LspTinymistGetDocumentMetrics`.
