## Regular setup
Follow the [Quick Start](../README.md) guide to install required software.
## Apple Silicon (emulated x86_64)
> Note: Steps for Apple Silicon is constantly changing and may not be accurate.
> Since January 2021 when these steps were written Apple Silicon support has improved significantly across the board and these steps may no longer be necessary.
1. install i386 Homebrew:
```
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
```
2. install `nvm` using i386 Homebrew:
```
arch -x86_64 /usr/local/bin/brew install nvm
```
**This is critical! If nvm is installed using ARM64 Homebrew, installed Node versions will also be the ARM64 variant and there will be problems!**
3. using `nvm`, install the current version of NodeJS used in `wp-calypso`:
```
nvm install
```
4. instruct `nvm` to use the version of NodeJS installed in previous step:
```
nvm use
```
5. update `npm` version:
```
arch -x86_64 npm install -g npm@latest
```
6. install `yarn`:
```
arch -x86_64 npm install yarn
```
7. install all dependencies from repo root:
```
arch -x86_64 yarn install --immutable
```
At any point, run `arch` to verify whether shell is running with Rosetta 2 emulation.
## Apple Silicon (arm64)
Steps in the [Setup](../README.md#quick-start) should be enough to get the user up and running.
