+### Usage with WASM
+
+Unfortunately using this parser with WASM/web-tree-sitter does not work out of the box at the moment. This is because the parser uses some C functions that are not exported by tree-sitter by default. To fix this you can statically link the parser to tree-sitter. See also https://github.com/tree-sitter/tree-sitter/issues/949, https://github.com/MDeiml/tree-sitter-markdown/issues/126, and https://github.com/MDeiml/tree-sitter-markdown/issues/93
