Revise Outdated Content in README.md #94
Description
It has been found that the information in README.md is outdated. For example, the "Data readers" section suggests using the DefaultErrorHandler structure to create specific error handlers in applications, yet the code description for DefaultErrorHandler has been removed.
The current state of README.md does not reflect the latest changes and does not match the current functionality. This can cause confusion for users, so updating the README is necessary.
