+#### Tmux Integration
+Harpoon also supports all terminal operations (see above) with tmux terminals. 
+The configuration for using tmux is exactly the same as the config for using nvim 
+terminals. To use tmux terminals instead of nvim terminals, simply replace 
+`harpoon.term` with `harpoon.tmux` in your require statement.
+
+For example:
+
+```lua
+-- goes to the first tmux window
+lua require("harpoon.tmux").gotoTerminal(1)
+
+-- sends a command to the first tmux window
+lua require("harpoon.tmux").sendCommand(1, "ls -la")
+```
