To change the format of Git status, open `~/.p10k.zsh`, search for `my_git_formatter` and edit its
source code.
### How do I add username and/or hostname to prompt?
When using *Lean*, *Classic* or *Rainbow* style, prompt shows `username@hostname` when you are
logged in as root or via SSH. There is little value showing `username` or `hostname` when you are
logged in to your local machine as a normal user. So the absence of `username@hostname` in your
prompt is an indication that you are working locally and that you aren't root. You can change it,
however.
Open `~/.p10k.zsh`. Close to the top you can see the most important parameters that define which
segments are shown in your prompt. All generally useful prompt segments are listed in there. Some of
them are enabled, others are commented out. One of them is of interest to you.
```zsh
typeset -g POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(
...
context # user@hostname
...
)
```
Search for `context` to find the section in the config that lists parameters specific to this prompt
segment. You should see the following lines there:
```zsh
# Don't show context unless running with privileges or in SSH.
# Tip: Remove the next line to always show context.
typeset -g POWERLEVEL9K_CONTEXT_{DEFAULT,SUDO}_{CONTENT,VISUAL_IDENTIFIER}_EXPANSION=
```
If you follow the tip and remove (or comment out) the last line, you'll always see
`username@hostname` in prompt. You can change the format to just `username`, or change the color, by
adjusting the values of parameters nearby. There are plenty of comments to help you navigate.
Finally, you can move `context` segment to where you want it to be in your prompt. Perhaps somewhere
within `POWERLEVEL9K_LEFT_PROMPT_ELEMENTS`.
### Why does Powerlevel10k spawn extra processes?
Powerlevel10k uses [gitstatus](https://github.com/romkatv/gitstatus) as the backend behind `vcs`
