+# git bisect
+
+> Use binary search to find the commit that introduced a bug.
+> Git automatically jumps back and forth in the commit graph to progressively narrow down the faulty commit.
+> More information: <https://git-scm.com/docs/git-bisect>.
+
+- Start a bisect session on a commit range bounded by a known buggy commit, and a known clean (typically older) one:
+
+`git bisect start {{bad_commit}} {{good_commit}}`
+
+- For each commit that `git bisect` selects, mark it as "bad" or "good" after testing it for the issue:
+
+`git bisect {{good|bad}}`
+
+- After `git bisect` pinpoints the faulty commit, end the bisect session and return to the previous branch:
+
+`git bisect reset`
+
+- Skip a commit during a bisect (e.g. one that fails the tests due to a different issue):
+
+`git bisect skip`
+
+- Display a log of what has been done so far:
+
+`git bisect log`
