This pull request includes changes to improve the clarity of the project documentation and test descriptions, as well as modifications to the process configuration in the haiku-src directory. The most important changes include updating the README.md file, changing the descriptions of several tests in haiku-tests.js, and modifying the process.json configuration file.

Documentation improvements:

• README.md: The text referring to the backup folder has been changed from "BACKUP folder" to "bkp fld". Additionally, two new paragraphs have been added for further explanation.

Test description updates:

• haiku-src/haiku-tests.js: The descriptions of three tests have been updated for clarity. The test for the root path now checks for "HTML stuff" instead of "HTML content". The test for the '/haikus' path now checks for "all haiku information" instead of "all haikus". The test for a nonexistent path now checks for a "detailed error message" instead of just an "error message". [1] [2] [3]

Process configuration changes:

• haiku-src/process.json: The process name has been changed from "worker" to "worker2". The interval for the watch options has been increased from 5 to 10. [1] [2]
