+
+# A few principles for repo setup:
+#
+# 1. GIT_DIR is relative to user's cwd. This directory is refered as
+# "git_dir" below. Auto discovered repo is also "git_dir".
+# --git-dir is equivalent to GIT_DIR.
+#
+# 2. core.worktree is relative to git_dir
+#
+# 3. GIT_WORK_TREE is relative to user's cwd. --work-tree is
+# equivalent to GIT_WORK_TREE.
+#
+# 4. .git file is relative to git_dir. Note that the repo where .git
+# file points to is not considered "git_dir" in the above.
+#
+# 5. GIT_WORK_TREE is only effective if GIT_DIR is
+# set (hence "Effective GIT_WORK_TREE"
+# below). Uneffective GIT_WORK_TREE should be warned.
+#
+# 6. Effective GIT_WORK_TREE will override core.worktree
+#
+# 7. During repo discovery, if "." is found a repo, it is considered a
+# bare repo unless core.worktree is set
+#
+# 8. core.bare conflicts with core.worktree
+#
+# 9. Effective GIT_WORK_TREE will override core.bare
+#
+# 10. When user's cwd is outside worktree, cwd will remain unchanged,
+# prefix be NULL.
