+# How you control your data
+
+When you use a Blockstack decentralized application (DApp), the data that you
+enter into that application, photos, documents, and more is something you own
+and control. Traditional applications such as Instagram or PayPal store your
+data _on their corporate servers_.
+
+Blockstack DApps do not allow applications to store your data on the
+application's corporate servers. Instead, you store your data with a _storage
+provider_ you choose. A storage provider gives you personal storage for your
+application data.
+
+If you want to walk away from a particular DApp, there’s no need even to export
+your data. You  simply stop using the DApp and it no longer can read or modify
+your data. And if you want to start using a different DApp with the same data,
+you can.
+
+## Understand storage providers
+
+The Blockstack Ecosystem provides a technology for data storage called, Gaia.
+Gaia is _storage hub_ technology for storing application data. A storage
+provider is simply an organization that implemented Gaia and is providing
+storage hubs for users. Any organization or person can create a Gaia storage hub
+and become a storage provider.
+
+These providers host data in one or more existing storage systems of their
+choice. These storage systems are typically cloud storage systems such as
+Amazon, Dropbox, iCloud or Azure to name a few.
+
+Users that create an identity in the Blockstack Browser are given a choice of
+which data storage provider to use. Blockstack itself runs a Gaia storage hub and acts
+as a storage provider. The default choice is the Blockstack-run storage hub.
+
+Every provider will store your data at a particular address or URL. These
+addresses look similar to any address you put in your web browser. When you log
+into a DApp, you are giving that the application the ability to save
+data to the URL on your behalf.
+
+## Current limitations of data storage
+
+The following are limitations of the current system.
+
+* You cannot move your storage from one provider to another.
+* You cannot store your data on your own computer.
+
+Blockstack is always seeking to expand Gaia's capabilities. These limitations
+will disappear as they are overcome by new Gaia features.

-## View your stacks
+You can use the Stacks Wallet software by itself or together with a hardware

+wallet_. You can view STX balances and transaction history.

+When you use the Stacks Wallet together with a hardware wallet, you can also
+send and receive Stacks. To do this, you must first top up the wallet's "gas" which is
+Bitcoin.  A **_very small_** amount of Bitcoin is required to send Stacks. No
+gas is required to receive Stacks. You can use any of these hardware wallets with the Stacks wallet:

-Suspendisse lectus elit, facilisis non mollis eu, rhoncus vel augue. Ut tempus
-vel felis sit amet viverra. Aenean eu congue orci. Morbi massa mauris,
+Once connected, the Stacks Wallet only uses the hardware wallet when signing
+send transactions. This means, you can connect to the hardware wallet when you
+start the Stacks Wallet software. After starting, you can disconnect the
+hardware wallet and put it away until you want to send Stacks.
+
+The **Reset** function is always available regardless of whether you are using a
+hardware wallet as well. A reset returns the Wallet Software to its original
+state. It does not change your Stacks balance or your hardware wallet in any
+way.
+
+
+## Open the wallet
+
+You can use the Stacks Wallet software with or without a hardware wallet. To
+send Stacks, a hardware wallet is required.
+
+### Stacks Wallet software only
+
+You need at least on Stacks Address to create a wallet. A Stacks address is a
+unique string of letters and numbers, for example:
+`SM7KJBA4UZ7Z20KD2HBXNSXVPCR1D7CRAV605MKT`.
+
+1. Double-click on the wallet software to open it.
+2. Select **Use a Stacks Address**.
+
+   The system asks you to enter an adddres. If you are a token holder, you
+   should have generated several Stacks address during your the initial grant
+   process. You can provide one of these addresses to the Stacks wallet when you
+   start it.
+
+   ![](images/enter-address.png)
+
+3. Select **Continue**.
+
+   The system displays the balance for that address.
+
+
+### Hardware wallet
+
+It is a good idea to connect your hardware wallet to your computer before
+starting the Stacks wallet software, but it is not required. Some hardware
+wallets require that you have additional software installed to support the
+hardware wallets interactions with the Stacks wallet.
+
+| Hardware wallet 	| Prerequisite software 	|
+|-----------------	|------------------------	|
+| Trezor One      	| <a href="https://doc.satoshilabs.com/trezor-user/download.html" target="\_blank">Trezor Bridge</a>          	|
+| Trezor Model T  	| <a href="https://doc.satoshilabs.com/trezor-user/download.html" target="\_blank">Trezor Bridge </a>         	|
+| Ledger Nano S   	| None.                  	|
+| Ledger Blue     	| None.                  	|
+
+Make sure you have installed any prerequisite software. Then, do the following to start the Stacks Wallet with a Hardware wallet:
+
+1. Connect your hardware wallet to your computer as you normally would.
+2. Double-click on the wallet software to open it.
+3. Select **Use a Hardware Wallet**.
+4. Select the hardware wallet you want to use.
+
+   This example uses a Trezor wallet.
+
+   ![](images/choose-hardware.png)
+
+   The system prompts you to connect your
+   device.
+
+5. Connect your wallet to your computer and choose **Continue**.
+
+   The system prompts you to export a public key.
+
+   ![](images/trezor-export.png)
+
+6. Select **Export**.
+
+   The Stacks Wallet shows the current wallet balance.
+
+
+
+## View Balance, Allocation, and transaction history
+
+The default view for an open and loaded wallet is the **Wallet Balance** view.
+
+![](images/hardware-balance.png)
+
+If you have started with a hardware wallet, your view includes **Send** and
+**Receive** buttons. If you open the same address in a watch-only wallet, you do
+not see these buttons:
+
+![](images/software-balance.png)
+
+Both balances show **Transaction History** if it exists for an address. A
+transaction summary appears on the initial screen. To see details,
+click on a transaction:
+
+![](images/receive-details.png)
+
+Not all addresses will have a balance. If you are a Stacks token holder, your
+address shows with both a **Balance** and **Allocation**. The **Balance** is the
+Stackes you have unlocked. The **Allocation** is the amount still locked up.
+
+![](images/token-holder-balance.png)
+
+
+## Receive Stacks
+
+To receive Stack you pass a STX address directly to a user via email, for
+example. If your Stackes Wallet is connected to a hardware wallet, click the **Receive** button to
+display an address where others can send Stacks to.
+
+![](images/receive-button.png)
+
+A stack address is a public addresses. Anyone with the address, can view the
+address balance or send money _**to**_ the address.
+
+{% include note.html content="Sending money <emphasis><u>from</u></emphasis> a
+Stacks address requires the private key. It is this private key together with
+your seed phrase that you should keep private and maintain with high security."
+%}
+
+Blockchain transactions take take time. There may be minutes or hours while the
+transaction is recorded in the blockchain. When the transaction is complete, you
+can see a receipt for the transaction in Software Wallet in watch-only mode or
+connected to a hardware wallet.
+
+
+## Reset the wallet
+
+Resetting a wallet clears all your data from the Stacks wallet and returns the
+wallet to its original state.
+
+* If you entered a Stacks address, resetting clears the address from the Stacks wallet.
+* If you connected to a hardware wallet, resetting removes the connection to the hardware wallet.
+
+Reseting the wallet does nothing to your addresses or their associated balances.
+They are maintained.
+
+Once you reset the wallet, you have to start over from the *Terms of Use*. If
+you do not restart the wallet, you can simple close it.
+
+
+1. Click the <span class="uk-margin-small-center" uk-icon="cog"></span>
+ (settings icon) in the upper right corner of the wallet.
+
+   The system opens the **Settings** dialog.
+
+   ![](images/settings.png)
+
+   The **Top Up** button is only visible when you have connected the Stacks
+   Wallet to a hardware wallet.
+
+2. Select **Reset Wallet**.
+
+   System asks for confirmation. If, for some reason, you want to stop the reset
+   you would press <span class="uk-margin-small-center" uk-icon="close"></span> (right corner) or **Close**.
+
+3. Select **Are you sure?** to complete the reset.
+
+   The wallet displays the **Terms of Use**. You can accept to enter the wallet
+   again or choose **Quit**.

+transactions. You can only receive Bitcoin with the wallet, you cannot send it
+from the Stacks Wallet. You need an account with Coinbase or similar exchange to
+buy Bitcoin or send it.
+
+If you attempt to send Stacks with your wallet and you do not have enough
+Bitcoin to fuel the transaction, you see this dialog:
