+	The data that follows the keyword `worktree` and a colon is used as a

++
+The worktree location is the path where files are checked out (as returned
+by `git rev-parse --show-toplevel`). This is different from `gitdir`, which
+matches the `.git` directory path. In a linked worktree, the worktree path
+is the directory where that worktree's files are located, not the main
+repository's `.git` directory.
++
+The pattern uses the same glob syntax as `gitdir` (including `~/`, `./`,
+`**/`, and trailing-`/` prefix matching). This condition will never match
+in a bare repository (which has no worktree).
++
+Unlike `gitdir`, the `worktree` condition currently matches only the
+realpath-resolved worktree location. If the working tree was entered via a
+symbolic link, a pattern that uses the symbolic-link spelling may not match;
+use the real path instead.
++
+This is useful when you want to apply configuration based on where the
+working tree is located on the filesystem. For example, a contributor who
+works on the same project both personally and as an employee can use
+different `user.name` and `user.email` values depending on which directory
+the worktree is checked out under:
++
+----

+[includeIf "worktree:/home/user/personal/"]
+    path = ~/.config/git/personal.inc
+----
++
+While `extensions.worktreeConfig` (see linkgit:git-worktree[1]) also supports
+per-worktree configuration, it stores the config inside each repository's
+`.git/config.worktree` file and requires running `git config --worktree`
+inside each worktree individually. In contrast, `includeIf "worktree:..."`
+can be set once in a global or system-level configuration file (e.g.
+`~/.config/git/config`) and applies to all repositories at once based on
+their worktree location.
