+## READ BEFORE OPENING ISSUES
+
+All bug reports require you to **USE CANARY BUILDS**. Please include the version name and version code in the bug report.
+
+If you experience a bootloop, attach a `dmesg` (kernel logs) when the device refuse to boot. This may very likely require a custom kernel on some devices as `last_kmsg` or `pstore ramoops` are usually not enabled by default. In addition, please also upload the result of `cat /proc/mounts` when your device is working correctly **WITHOUT ROOT**.
+
+If you experience issues during installation, in recovery, upload the recovery logs, or in Magisk Manager, upload the install logs. Please also upload the `boot.img` or `recovery.img` that you are using for patching.
+
+If you experience a crash of Magisk Manager, dump the full `logcat` **when the crash happens**. **DO NOT** upload `magisk.log`.
+
+If you experience other issues related to Magisk, upload `magisk.log`, and preferably also include a boot `logcat` (start dumping `logcat` when the device boots up)
+
+**DO NOT** open issues regarding root detection.
+
+**DO NOT** ask for instructions.
+
+**DO NOT** report issues if you have any modules installed.
+
+Without following the rules above, your issue will be closed without explanation.
