Worked on the grafana/grafana repository to enhance dashboard variable settings by updating documentation to clarify the valid regex pattern for the Custom all value. This contribution focused on improving user guidance and reducing configuration errors by providing clear, actionable instructions within the Markdown-based documentation. Leveraging skills in documentation, regex, and user interface design, the work addressed a common pain point for users configuring dashboard variables. No bugs were fixed during this period, as the primary emphasis was on feature documentation. The update aimed to streamline the configuration workflow, reduce support requests, and improve the overall user experience for Grafana administrators.
