+#
+# A few rules for repo setup:
+#
+# 1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
+# GIT_DIR.
+#
+# 2. .git file is relative to parent directory. .git file is basically
+# symlink in disguise. The directory where .git file points to will
+# become new git_dir.
+#
+# 3. core.worktree is relative to git_dir.
+#
+# 4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
+# equivalent to GIT_WORK_TREE.
+#
+# 5. GIT_WORK_TREE/core.worktree is only effective if GIT_DIR is set
+# Uneffective worktree settings should be warned.
+#
+# 6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
+#
+# 7. Effective core.worktree conflicts with core.bare
+#
+# 8. If GIT_DIR is set but neither worktree nor bare setting is given,
+# original cwd becomes worktree.
+#
+# 9. If .git discovery is done inside a repo, the repo becomes a bare
+# repo. .git discovery is performed if GIT_DIR is not set.
+#
+# 10. If no worktree is available, cwd remains unchanged, prefix is
+# NULL.
+#
+# 11. When user's cwd is outside worktree, cwd remains unchanged,
+# prefix is NULL.
