-**What it does**
-
-Detects method overrides that violate the [Liskov Substitution Principle] ("LSP").
-
-The LSP states that an instance of a subtype should be substitutable for an instance of its supertype.
-Applied to Python, this means:
-1. All argument combinations a superclass method accepts
-   must also be accepted by an overriding subclass method.
-2. The return type of an overriding subclass method must be a subtype
-   of the return type of the superclass method.
-
-**Why is this bad?**
-
-Violating the Liskov Substitution Principle will lead to many of ty's assumptions and
-inferences being incorrect, which will mean that it will fail to catch many possible
-type errors in your code.
-
-**Example**
-
-```python
-class Super:
-    def method(self, x) -> int:
-        return 42
-
-class Sub(Super):
-    # Liskov violation: `str` is not a subtype of `int`,
-    # but the supertype method promises to return an `int`.
-    def method(self, x) -> str:  # error: [invalid-override]
-        return "foo"
-

-
-**Common issues**
-
-
-**Why does ty complain about my `__eq__` method?**
-
-
-`__eq__` and `__ne__` methods in Python are generally expected to accept arbitrary
-objects as their second argument, for example:
-
-```python
-class A:
-    x: int
-
-    def __eq__(self, other: object) -> bool:
-        # gracefully handle an object of an unexpected type
-        # without raising an exception
-        if not isinstance(other, A):
-            return False
-        return self.x == other.x
-```
-
-If `A.__eq__` here were annotated as only accepting `A` instances for its second argument,
-it would imply that you wouldn't be able to use `==` between instances of `A` and
-instances of unrelated classes without an exception possibly being raised. While some
-classes in Python do indeed behave this way, the strongly held convention is that it should
-be avoided wherever possible. As part of this check, therefore, ty enforces that `__eq__`
-and `__ne__` methods accept `object` as their second argument.
