+
+cJSON doesn't support arrays and objects that are nested too deeply because this would result in a stack overflow. To prevent this cJSON limits the depth to `CJSON_NESTING_LIMIT` which is 1000 by default but can be changed at compile time.

 * `cJSON_InitHooks` is only ever called before using cJSON in any threads.
 * `setlocale` is never called before all calls to cJSON functions have returned.
 
+#### Case Sensitivity
+
+When cJSON was originally created, it didn't follow the JSON standard and didn't make a distinction between uppercase and lowercase letters. If you want the correct, standard compliant, behavior, you need to use the `CaseSensitive` functions where available.

+JSON Patch Tests
+================
+
+These are test cases for implementations of [IETF JSON Patch (RFC6902)](http://tools.ietf.org/html/rfc6902).
+
+Some implementations can be found at [jsonpatch.com](http://jsonpatch.com).
+
+
+Test Format
+-----------
+
+Each test file is a JSON document that contains an array of test records. A
+test record is an object with the following members:
+
+- doc: The JSON document to test against
+- patch: The patch(es) to apply
+- expected: The expected resulting document, OR
+- error: A string describing an expected error
+- comment: A string describing the test
+- disabled: True if the test should be skipped
+
+All fields except 'doc' and 'patch' are optional. Test records consisting only
+of a comment are also OK.
+
+
+Files
+-----
+
+- tests.json: the main test file
+- spec_tests.json: tests from the RFC6902 spec
+
+
+Writing Tests
+-------------
+
+All tests should have a descriptive comment.  Tests should be as
+simple as possible - just what's required to test a specific piece of
+behavior.  If you want to test interacting behaviors, create tests for
+each behavior as well as the interaction.
+
+If an 'error' member is specified, the error text should describe the
+error the implementation should raise - *not* what's being tested.
+Implementation error strings will vary, but the suggested error should
+be easily matched to the implementation error string.  Try to avoid
+creating error tests that might pass because an incorrect error was
+reported.
+
+Please feel free to contribute!
+
