+Tools for developing Git

+[[summary]]
+== Summary
+
+This document gathers tips, scripts, and configuration files to help people
+working on Git's codebase use their favorite tools while following Git's
+coding style.

+
+[[vscode]]
+=== Visual Studio Code (VS Code)
+
+The contrib/vscode/init.sh script creates configuration files that enable
+several valuable VS Code features. See contrib/vscode/README.md for more
+information on using the script.
+
+[[emacs]]
+=== Emacs
+
+This is adapted from Linux's suggestion in its CodingStyle document:
+
+- To follow the rules in CodingGuidelines, it's useful to put the following in
+GIT_CHECKOUT/.dir-locals.el, assuming you use cperl-mode:
+----
+;; note the first part is useful for C editing, too
+((nil . ((indent-tabs-mode . t)
+	 (tab-width . 8)
+	 (fill-column . 80)))
+	 (cperl-mode . ((cperl-indent-level . 8)
+			(cperl-extra-newline-before-brace . nil)
+			(cperl-merge-trailing-else . t))))
+----
+
+For a more complete setup, since Git's codebase uses a coding style
+similar to the Linux kernel's style, tips given in Linux's CodingStyle
+document can be applied here too.
