I ran into an issue after migrating, admin-fe wouldn't function properly. Ran the above command for my build, and got that functionality back.
### I just run with the built-in frontend
-You'll need to run a single command,
+You'll need to run a couple of commands,
```bash
# From source
mix pleroma.frontend install pleroma-fe
+# you'll probably want this too
+mix pleroma.frontend install admin-fe
+
# OTP
./bin/pleroma_ctl frontend install pleroma-fe
+# you'll probably want this too
+./bin/pleroma_ctl frontend install admin-fe
```
### I've run the mix task to install a frontend
