+## What should I do before opening an issue?
+
+Before opening an issue, please ensure that:
+
+- Your problem is a specific problem or question or suggestion, not a general
+  complaint.
+
+- `$TERM` inside tmux is screen, screen-256color, tmux or tmux-256color. Check
+  by running `echo $TERM` inside tmux.
+
+- You can reproduce the problem with the latest tmux release, or a build from
+  Git master.
+
+- Your question or issue is not covered [in the
+  manual](https://man.openbsd.org/tmux.1) (run `man tmux`).
+
+- Your problem is not mentioned in [the CHANGES
+  file](https://raw.githubusercontent.com/tmux/tmux/master/CHANGES).
+
+- Nobody else has opened the same issue recently.
+
+## What should I include in an issue?
+
+Please include the output of:
+
+~~~bash
+uname -sp && tmux -V && echo $TERM
+~~~
+
+Also include:
+
+- Your platform (Linux, OS X, or whatever).
+
+- A brief description of the problem with steps to reproduce.
+
+- A minimal tmux config, if you can't reproduce without a config.
+
+- Your terminal, and `$TERM` inside and outside of tmux.
+
+- Logs from tmux (see below).
+
+- At most one or two screenshots, if helpful.
+
+## How do I test without a .tmux.conf?
+
+Run a separate tmux server with `-f/dev/null` to skip loading `.tmux.conf`:
+
+~~~bash
+tmux -Ltest kill-server
+tmux -Ltest -f/dev/null new
+~~~
+
+## How do I get logs from tmux?
+
+Add `-vv` to tmux to create three log files in the current directory. If you can
+reproduce without a configuration file:
+
+~~~bash
+tmux -Ltest kill-server
+tmux -vv -Ltest -f/dev/null new
+~~~
+
+Or if you need your configuration:
+
+~~~base
+tmux kill-server
+tmux -vv new
+~~~
+
+The log files are:
+
+- `tmux-server*.log`: server log file.
+
+- `tmux-client*.log`: client log file.
+
+- `tmux-out*.log`: output log file.
+
+Please attach the log files to your issue.
