 ## Known issues & workarounds
 
-### Error: unknown command "quick-start" for "ddev"
-
-If you see an error like below and have already installed `starshot` before, you will need to use a different name for your directory since ddev can't have two projects with the same name.
-
-```
-$ ddev quick-start
-Error: unknown command "quick-start" for "ddev"
-Run 'ddev --help' for usage.
-```
-
-The workaround is to use something unique, e.g.
-
-```
-git clone https://github.com/phenaproxima/starshot-prototype.git starshot2
-cd starshot2 && ddev quick-start
-```
+### `Error: unknown command "quick-start" for "ddev"`
+If you see an error like this, you probably previously installed Starshot with DDEV in another directory with the same name as the current one. DDEV can't have two projects with the same directory name, so change the directory name to something unique and try `ddev quick-start` again.
 
 ### Server timeout
 Some users might experience a timeout after logging into Starshot, particularly when the PHP web server remains idle for some time.
