-## Git bisect exercise
-
-### Motivation
-
-The motivation for this exercise is to be able to do archaeology with Git on a
-source code where the bug is difficult to see visually. **Finding the offending
-commit is often more than half the debugging**.
-
-
-### Background
-
-The script `get_pi.py` approximates pi using terms of the Nilakantha series. It
-should produce 3.14 but it does not. The script broke at some point and
-produces 3.57 using the last commit:
-
-```
-$ python get_pi.py
-
-3.57
-```
-
-At some point within the 500 first commits, an error was introduced. The only
-thing we know is that the first commit worked correctly.
-
-
-### Your task
-
-Clone or fork this repository and use `git bisect` to find the commit which
-broke the computation.
