+```

-* see also: [#12](https://github.com/ChesterYue/ohmyzsh-theme-passion/issues/12);
+```shell:~/.zshrc
+# Find the line that reads ZSH_THEME="..." and replace it with the following code.
+ZSH_THEME="simplerich"
+```
 
-##### Linux, command not found: bc
+4. Load ~/.zshrc:
 
-* passion.zsh-theme depends on cmd ```bc``` to calculate the command running time cost. [get bc on Linux](https://www.tecmint.com/bc-command-examples/#:~:text=If%20you%20don%E2%80%99t%20have%20bc%20on%20your%20system%2C,command%20prompt%20and%20simply%20start%20calculating%20your%20expressions.) then ```source ~/.zshrc```;
