 **NOTE:** When asking for support, it may be a good idea to have the following available so that the person helping has all the info they need:

-2. The Gitea logs, and any other appropriate log files for the situation.
+2. Any error messages you are seeing.
+3. The Gitea logs, and all other related logs for the situation.
+   - It's more useful to collect `trace` / `debug` level logs (see the next section).
    - When using systemd, use `journalctl --lines 1000 --unit gitea` to collect logs.
    - When using docker, use `docker logs --tail 1000 <gitea-container>` to collect logs.
-    - By default, the logs are outputted to console. If you need to collect logs from files,
-      you could copy the following config into your `app.ini` (remove all other `[log]` sections),
-      then you can find the `*.log` files in Gitea's log directory (default: `%(GITEA_WORK_DIR)/log`).
+4. Reproducible steps so that others could reproduce and understand the problem more quickly and easily.
+   - [try.gitea.io](https://try.gitea.io) could be used to reproduce the problem.
+5. If you encounter slow/hanging/deadlock problems, please report the stacktrace when the problem occurs.
