-# Red Knot
-
-Red Knot is an extremely fast type checker.
-Currently, it is a work-in-progress and not ready for user testing.
-
-Red Knot is designed to prioritize good type inference, even in unannotated code,
-and aims to avoid false positives.
-
-While Red Knot will produce similar results to mypy and pyright on many codebases,
-100% compatibility with these tools is a non-goal.
-On some codebases, Red Knot's design decisions lead to different outcomes
-than you would get from running one of these more established tools.
-
-## Contributing
-
-Core type checking tests are written as Markdown code blocks.
-They can be found in [`red_knot_python_semantic/resources/mdtest`][resources-mdtest].
-See [`red_knot_test/README.md`][mdtest-readme] for more information
-on the test framework itself.
-
-The list of open issues can be found [here][open-issues].

-# Suppressing errors with `knot: ignore`
-
-Type check errors can be suppressed by a `knot: ignore` comment on the same line as the violation.
-
-## Simple `knot: ignore`
-
-```py
-a = 4 + test  # knot: ignore
-```
-
-## Suppressing a specific code
-
-```py
-a = 4 + test  # knot: ignore[unresolved-reference]
-```
-
-## Unused suppression
-
-```py
-test = 10
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'possibly-unresolved-reference'"
-a = test + 3  # knot: ignore[possibly-unresolved-reference]
-```
-
-## Unused suppression if the error codes don't match
-
-```py
-# error: [unresolved-reference]
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'possibly-unresolved-reference'"
-a = test + 3  # knot: ignore[possibly-unresolved-reference]
-```
-
-## Suppressed unused comment
-
-```py
-# error: [unused-ignore-comment]
-a = 10 / 2  # knot: ignore[division-by-zero]
-a = 10 / 2  # knot: ignore[division-by-zero, unused-ignore-comment]
-a = 10 / 2  # knot: ignore[unused-ignore-comment, division-by-zero]
-a = 10 / 2  # knot: ignore[unused-ignore-comment] # type: ignore
-a = 10 / 2  # type: ignore # knot: ignore[unused-ignore-comment]
-```
-
-## Unused ignore comment
-
-```py
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'unused-ignore-comment'"
-a = 10 / 0  # knot: ignore[division-by-zero, unused-ignore-comment]
-```
-
-## Multiple unused comments
-
-Today, Red Knot emits a diagnostic for every unused code. We might want to group the codes by
-comment at some point in the future.
-
-```py
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'division-by-zero'"
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'unresolved-reference'"
-a = 10 / 2  # knot: ignore[division-by-zero, unresolved-reference]
-
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'invalid-assignment'"
-# error: [unused-ignore-comment] "Unused `knot: ignore` directive: 'unresolved-reference'"
-a = 10 / 0  # knot: ignore[invalid-assignment, division-by-zero, unresolved-reference]
-```
-
-## Multiple suppressions
-
-```py
-# fmt: off
-def test(a: f"f-string type annotation", b: b"byte-string-type-annotation"): ...  # knot: ignore[fstring-type-annotation, byte-string-type-annotation]
-```
-
-## Can't suppress syntax errors
-
-<!-- blacken-docs:off -->
-
-```py
-# error: [invalid-syntax]
-# error: [unused-ignore-comment]
-def test($):  # knot: ignore
-    pass
-```
-
-<!-- blacken-docs:on -->
-
-## Can't suppress `revealed-type` diagnostics
-
-```py
-a = 10
-# revealed: Literal[10]
-# error: [unknown-rule] "Unknown rule `revealed-type`"
-reveal_type(a)  # knot: ignore[revealed-type]
-```
-
-## Extra whitespace in type ignore comments is allowed
-
-```py
-a = 10 / 0  # knot   :   ignore
-a = 10 / 0  # knot: ignore  [    division-by-zero   ]
-```
-
-## Whitespace is optional
-
-```py
-# fmt: off
-a = 10 / 0  #knot:ignore[division-by-zero]
-```
-
-## Trailing codes comma
-
-Trailing commas in the codes section are allowed:
-
-```py
-a = 10 / 0  # knot: ignore[division-by-zero,]
-```
-
-## Invalid characters in codes
-
-```py
-# error: [division-by-zero]
-# error: [invalid-ignore-comment] "Invalid `knot: ignore` comment: expected a alphanumeric character or `-` or `_` as code"
-a = 10 / 0  # knot: ignore[*-*]
-```
-
-## Trailing whitespace
-
-<!-- blacken-docs:off -->
-
-```py
-a = 10 / 0  # knot: ignore[division-by-zero]      
-            #                               ^^^^^^ trailing whitespace
-```
-
-<!-- blacken-docs:on -->
-
-## Missing comma
-
-A missing comma results in an invalid suppression comment. We may want to recover from this in the
-future.
-
-```py
-# error: [unresolved-reference]
-# error: [invalid-ignore-comment] "Invalid `knot: ignore` comment: expected a comma separating the rule codes"
-a = x / 0  # knot: ignore[division-by-zero unresolved-reference]
-```
-
-## Missing closing bracket
-
-```py
-# error: [unresolved-reference] "Name `x` used when not defined"
-# error: [invalid-ignore-comment] "Invalid `knot: ignore` comment: expected a comma separating the rule codes"
-a = x / 2  # knot: ignore[unresolved-reference
-```
-
-## Empty codes
-
-An empty codes array suppresses no-diagnostics and is always useless
-
-```py
-# error: [division-by-zero]
-# error: [unused-ignore-comment] "Unused `knot: ignore` without a code"
-a = 4 / 0  # knot: ignore[]
-```
-
-## File-level suppression comments
-
-File level suppression comments are currently intentionally unsupported because we've yet to decide
-if they should use a different syntax that also supports enabling rules or changing the rule's
-severity: `knot: possibly-undefined-reference=error`
-
-```py
-# error: [unused-ignore-comment]
-# knot: ignore[division-by-zero]
-
-a = 4 / 0  # error: [division-by-zero]
-```
-
-## Unknown rule
-
-```py
-# error: [unknown-rule] "Unknown rule `is-equal-14`"
-a = 10 + 4  # knot: ignore[is-equal-14]
-```
-
-## Code with `lint:` prefix
-
-```py
-# error:[unknown-rule] "Unknown rule `lint:division-by-zero`. Did you mean `division-by-zero`?"
-# error: [division-by-zero]
-a = 10 / 0  # knot: ignore[lint:division-by-zero]
-```

+# ty
+
+ty is an extremely fast type checker.
+Currently, it is a work-in-progress and not ready for user testing.
+
+ty is designed to prioritize good type inference, even in unannotated code,
+and aims to avoid false positives.
+
+While ty will produce similar results to mypy and pyright on many codebases,
+100% compatibility with these tools is a non-goal.
+On some codebases, ty's design decisions lead to different outcomes
+than you would get from running one of these more established tools.
+
+## Contributing
+
+Core type checking tests are written as Markdown code blocks.
+They can be found in [`ty_python_semantic/resources/mdtest`][resources-mdtest].
+See [`ty_test/README.md`][mdtest-readme] for more information
+on the test framework itself.
