+.TH fzf-tmux 1 "Jun 2023" "fzf 0.42.0" "fzf-tmux - open fzf in tmux split pane"
+
+.SH NAME
+fzf-tmux - open fzf in tmux split pane
+
+.SH SYNOPSIS
+.B fzf-tmux [LAYOUT OPTIONS] [--] [FZF OPTIONS]
+
+.SH DESCRIPTION
+fzf-tmux is a wrapper script for fzf that opens fzf in a tmux split pane or in
+a tmux popup window. It is designed to work just like fzf except that it does
+not take up the whole screen. You can safely use fzf-tmux instead of fzf in
+your scripts as the extra options will be silently ignored if you're not on
+tmux.
