Worked on the apache/ignite-3 repository to enhance documentation accuracy, focusing on improving the Developer’s Guide for client onboarding. Addressed a versioning issue by updating references from Ignite 8.x to Ignite 2.x, ensuring that users receive correct information when connecting to the cluster. This change, implemented using adoc and documentation best practices, aimed to reduce confusion and minimize support requests related to version mismatches. The work involved careful review and precise editing of technical content, reflecting attention to detail and a commitment to quality. No new features were added, but the update contributed to clearer, more reliable project documentation.
