-
-The [Natvis](https://learn.microsoft.com/en-us/visualstudio/debugger/create-custom-views-of-native-objects) file that
-gives `json` values a friendly view in the Visual Studio debugger. The file is generated by
-`tools/generate_natvis/generate_natvis.py` from the template `tools/generate_natvis/nlohmann_json.natvis.j2` and the ABI
-tags and version in `include/nlohmann/detail/abi_macros.hpp`; change the script or the template rather than editing
-the file by hand. The file can be updated by calling
-
-```shell
-make natvis
-```
-
-The "Check amalgamation" workflow fails if the file is out of date.
-
-The file covers the namespace variants with up to two ABI tags. A Natvis file for other configurations can be
-generated with the `--abi-tags` or `--all` options, for example
-`make natvis NATVIS_ARGS="--abi-tags _diag,_dp,_ns --output my_nlohmann_json.natvis"`; see
-[`tools/generate_natvis`](tools/generate_natvis/README.md). With MSVC, CMake adds the file to the `nlohmann_json`

 ## Notes

- Currently, only `remove`, `add`, and `replace` operations are generated.
- The patch is correct, but not guaranteed to be minimal. For instance, `diff([1,2,3], [0,1,2,3])` yields three
-  `replace` operations and one `add` operation instead of a single insertion.
- Differences between two arrays are reported index by index. Elements that were added at the end of the array are added
-  with `add` operations on the path `/-` (appended in order), and elements that were removed are removed with `remove`
-  operations from the highest index down to the lowest, so that the remaining indices stay valid.
- For objects, the operations for the members of `source` come first (`replace`, `remove`, or the operations for nested
-  values, in the iteration order of `source`), followed by `add` operations for the members that only `target` has.
- For [`ordered_json`](../ordered_json.md), objects with the same keys in a different order are different. As a patch
-  cannot reorder members, `diff` removes all keys of the `source` object and adds them again in the order of the
-  `target`.
- If `source` and `target` differ as a whole (e.g., different types), the patch consists of a single `replace`
-  operation for the root of the value, i.e., with the `path` `""` (or the given `path` prefix).
- The `value` members of the patch hold copies of values of `target`. A [binary](../../features/binary_values.md) value
-  has no JSON representation: when a patch that contains one is serialized, it becomes an object such as
-  `#!json {"bytes":[1,3],"subtype":null}`, so a parsed patch no longer holds a binary value (and would set that object
