+
+To work with Tezos, you need a wallet, which is an application that maintains your accounts and signs Tezos transactions on your behalf.
+Wallets allow you to interact with dApps without exposing your account's private key.
+
+## Choosing a wallet
+
+Which wallet you install is up to you and whether you want to install a wallet on your computer, in a browser extension, or as a mobile app.
+
+Mobile apps include [Temple](https://templewallet.com/), [Kukai](https://wallet.kukai.app/), and [Umami](https://umamiwallet.com/).
+
+Browser extensions include the [Temple](https://templewallet.com/) browser extension.
+
+Desktop wallets for Tezos include [Kukai](https://wallet.kukai.app/) and [Umami](https://umamiwallet.com/).
+
+## Switching the wallet to a testnet
+
+If you're doing development work, you're probably using a testnet instead of Mainnet.
+On testnets, tokens are free so you don't have to spend real currency to work with your applications.
+
+The process for changing the network is different for each wallet type.
+These steps are for the Temple wallet:
+
+1. Go to https://teztnets.xyz/, which lists Tezos testnets.
+1. Click **Ghostnet**.
+1. Copy one of the public RPC endpoints for Ghostnet, such as `https://rpc.ghostnet.teztnets.xyz`.
+These URLs accept Tezos transactions from wallets and other applications.
+1. In the Temple app, open the settings and then click **Default node (RPC)**.
+1. Click the plus `+` symbol to add an RPC node.
+1. On the Add RPC screen, enter the URL that you copied and give the connection a name, such as "Ghostnet," as shown in this picture:
+
+    <img src="/img/dApps/temple-wallet-new-rpc.png" alt="Entering information for the new RPC node" style={{width: 300}} />
+1. Click Add.
+1. Make sure that the new RPC node is selected, as in this image:
+
+    <img src="/img/dApps/temple-wallet-selected-rpc.png" alt="The new RPC node selected in the Temple wallet" style={{width: 300}} />
+
+## Funding a wallet
+
+Follow these steps to get testnet tez for the wallet:
+
+1. From your wallet, get the address of your account, which starts with `tz1`.
+This is the address that applications use to work with your wallet.
+
+1. Go to the Ghostnet faucet at https://faucet.ghostnet.teztnets.xyz.
+
+1. On the faucet page, paste your wallet address into the input field labeled "Or fund any address" and click the button for the amount of tez to add to your wallet.
+20 tez is enough to work with, and you can return to the faucet later if you need more tez.
+
+It may take a few minutes for the faucet to send the tokens and for those tokens to appear in your wallet.
+
+You can use the faucet as much as you need to get tokens on the testnet, but those tokens are worthless and cannot be used on Mainnet.
