 ## Issues and Workarounds
 
 
-#### The text is too long for my terminal window and wraps to the next line
-
-There are a few ways to fix this.
-
-* Disable line wrapping with `line_wrap=off` in the script or with the launch flag `--line_wrap off`
-* The uptime and gtk info lines each have a shorthand option that makes their output smaller. You can <br \>
-  enable them by changing these variables or using these flags.
-
-```sh
-# Config options
-uptime_shorthand="on"
-gtk_shorthand="on"
-gpu_shorthand="on"
-birthday_shorthand="on"
-
-# Launch flags
---uptime_shorthand on
---gtk_shorthand on
---gpu_shorthand on
---birthday_shorthand on
-
-```
-
-* Edit the config to make the subtitles shorter
-* Resizing the terminal so that the lines don't wrap.
-
-
 #### The text is pushed over too far to the right
 
 The easiest way to fix this is to change the value of `--gap` or `$gap`<br \>
