### Test strategy
@ -76,42 +76,38 @@ I'm very new to Rust, so any help is appreciated when it comes to improving deve
### Prerequisites
- Rust v1.33 or higher
- A Powerline font (like [Fira Code](https://github.com/tonsky/FiraCode)) installed and enabled in your terminal emulator
### Getting Started
1. `cd` to the root of the **starship** repo
1. Install the **starship** binary:
```bash
cargo install --path .
```
1. Navigate to the adapters directory
1. Add the init script to your shell's config file:
#### Bash / Zsh
Add the following to the end of `~/.bashrc` or `~/.zshrc`:
```bash
cd adapters
# ~/.bashrc or ~/.zshrc
eval "$(starship init $0)"
```
#### Fish
1. Install the fish shell prompt with fisher:
Add the following to the end of `~/.config/fish/config.fish`:
```bash
fisher add $PWD
```
```fish
# ~/.config/config.fish
#### oh-my-zsh
1. Install the zsh theme:
```bash
cp starship.zsh-theme ~/.oh-my-zsh/themes
```
1. In `~/.zshrc`, find the line with `ZSH_THEME=` and set it to
```bash
ZSH_THEME="starship"
eval (starship init fish)
```
