 ## Configuration
 
+### TERM name, true color and osc 52 copy
+
+You may need to modify the name of your `$TERM` in the "terminal-features" & "terminal-overrides" inside tmux.conf.
+
+Your terminal need features related to 256 or true colors and OSC 52 copy.
+
+### URxvt - Rxvt-unicode
+
+Urxvt is an old terminal but it is currently my favorite due to the amount of customizations available and it's performance.
+
+By default it can not perform OSC 52 or display some font icons. Please refer to my other repository [urxvtrc][urxvtrc_repo].
+
 ### SSH/Remote
 
 If you install this configuration on a remote system, you will need another prefix than on the local tmux (ctrl+x).
