 ## Uninstall
+
 To uninstall the pixi binary should be removed.
 Delete `pixi` from the `$PIXI_DIR` which is default to `~/.pixi/bin/pixi`
 
 So on Linux its:
+
 ```shell
 rm ~/.pixi/bin/pixi
 ```
+
 and on Windows:
+
 ```shell
 $PIXI_BIN = "$Env:LocalAppData\pixi\bin\pixi"; Remove-Item -Path $PIXI_BIN
 ```
+
 After this command you can still use the tools you installed with `pixi`.
 To remove these as well just remove the whole `~/.pixi` directory and remove the directory from your path.
