# Lido v3 stVaults (WIP)

## Installing Dependencies

Remove the incorrect `yarn` package

```
sudo apt remove -y nodejs
```

Install the correct `yarn` package.

```
nvm install 22
nvm use 22
nvm alias default 22
node --version
```

Enable Corepack under `Node 22` and activate `yarn`.

```
corepack enable
corepack prepare yarn@stable --activate
hash -r
which yarn
yarn --version
```

**Expected:** `which yarn` should point to a Corepack-managed path and `yarn --version` should return a normal Yarn version (e.g., `1.22.x` or `3.x/4.x`), not error.

Reload your shell startup file.

```
source ~/.bashrc
```

Install other dependencies for running stVaults.

```
cd ~/lido-staking-vault-cli
yarn install
```
