+title: Community & Support
+description: Join the KTX Slack community, report bugs, and get help.
+---
+
+KTX is an open-source project. The community is where users, contributors, and
+the core team trade questions, share patterns, and shape the roadmap.
+
+## Where to go
+
+| You want to... | Go here |
+|----------------|---------|
+| Ask a question or chat with the community | [KTX Slack](https://join.slack.com/t/ktxcommunity/shared_invite/zt-3y9b44m1x-LVyNNJD5nwaZHq4XS29LMQ) |
+| Report a bug or request a feature | [GitHub Issues](https://github.com/Kaelio/ktx/issues) |
+| Read or contribute to the docs | [docs.kaelio.com/ktx](https://docs.kaelio.com/ktx/docs/) |
+| Contribute code | [Contributing guide](/docs/community/contributing) |
+
+## Slack
+
+Join the KTX Slack to ask questions, share what you're building, and get help
+from maintainers and other users.
+
+[**Join the KTX Slack →**](https://join.slack.com/t/ktxcommunity/shared_invite/zt-3y9b44m1x-LVyNNJD5nwaZHq4XS29LMQ)
+
+Slack is the right place for:
+
+- **Setup and configuration questions** that don't fit a bug report
+- **Quick "how do I..."** questions
+- **Sharing patterns** for prompts, semantic-layer definitions, or agent workflows
+- **Feedback** on the roadmap and early features
+
+For anything reproducible - a crash, a wrong result, an unexpected CLI error -
+open a [GitHub issue](https://github.com/Kaelio/ktx/issues) instead. Issues are
+searchable, get triaged, and stay attached to the eventual fix.
+
+## GitHub
+
+- **[Issues](https://github.com/Kaelio/ktx/issues)** - bugs and feature requests
+- **[Pull requests](https://github.com/Kaelio/ktx/pulls)** - code, docs, and connector contributions
+- **[Releases](https://github.com/Kaelio/ktx/releases)** - changelog and published versions
