**It is recommended** to always use `lemonbuddy_wrapper` when launching the bars.
`lemonbuddy_wrapper` is just a simple shell script that takes care
of redirecting the in-/output streams between `lemonbuddy` and `lemonbar`.
If you handle the in-/output stream redirection's manually, the internal command
handlers (e.g. mpd or volume controls) might stop working. It won't change the
output of the bar but you will miss out on the internal API calls, which is one
of the main advantages of using the application.
The `lemonbuddy_wrapper` will be deprecated once `lemonbar` is integrated
into the project.
> **NOTE:** In case the bar output looks odd, it's probably because you're
> missing he fonts defined in the config. Update the config or install the
> missing fonts.
## Launching the bar in your wm's bootstrap routine
When using the wrapper to start the bar in in your wm's autostart routine, make sure to include
a kill directive before launching the bar. This is done to make sure that any previously spawned
processes gets terminated before before we launch the new ones.
Create an executable file containing the startup logic, for example `$HOME/.config/lemonbuddy/launch.sh`:
~~~ sh
#!/usr/bin/env sh
# Terminate already running bar instances
lemonbuddy_terminate noconfirm
killall -q lemonbuddy
# Launch bar1 and bar2
lemonbuddy_wrapper bar1 &
lemonbuddy_wrapper bar2 &
lemonbuddy bar1 &
lemonbuddy bar2 &

### Fonts
When working with unicode symbols, remember that fonts render the symbols differently. Changing font
can drastically improve the quality of your bar. One must-have font
is [Unifont](http://unifoundry.com/unifont.html), which has great unicode coverage.
