 # Using Parsers
 
-All of Tree-sitter's parsing functionality is exposed through C APIs. Applications written in higher-level languages can use Tree-sitter via binding libraries like  [node-tree-sitter](https://github.com/tree-sitter/node-tree-sitter) or [rust-tree-sitter](https://github.com/tree-sitter/rust-tree-sitter), which have their own documentation.

 This document will describes the general concepts of how to use Tree-sitter, which should be relevant regardless of what language you're using. It also goes into some C-specific details that are useful if you're using the C API directly or are building a new binding to a different language.

-Building the runtime library requires one git submodule: [`utf8proc`](https://github.com/JuliaStrings/utf8proc). Make sure that `utf8proc` is downloaded by running this command from the Tree-sitter directory:

-To build the runtime library on a POSIX system, run this script, which will create a static library called `libruntime.a` in the Tree-sitter folder:

-Alternatively, you can use the runtime library in a larger project by adding one source file to the project. This source file needs three directories to be in the include path when compiled:
