+<h1>Create Wallet</h1>
+A wallet can be created in a number of ways:
+<ul>
+    <li>New Address</li>
+    <li>Recover from Seed</li>
+    <li>Recover from Keys</li>
+    <li>View Only</li>
+</ul>
+In all cases you need to name your wallet and give it a password. The password is used for
+securing your wallet data on the device. Use a strong password - better a passphrase.
+
+<h2>New Address</h2>
+You need a new Monero Address - no need to enter additional info.
+<h3>Take Note of your Mnemonic Seed!</h3>
+<p>
+    On the following screen you will find your 25-word "Mnemonic Seed".
+    This is the only data needed to recover your wallet at a later time
+    and gain full access to your funds.
+    Keeping this secure and private is very important, as it gives <em>anyone</em>
+    full access to your funds!
+</p>
+<p>
+    If you loose your wallet password, you can still recover your wallet with the mnemonic seed.
+</p>
+<p>
+    There is no way to recover it if it is lost! Your funds would be lost.
+    The mnemonic seed can also never be changed, and if it is stolen or otherwise compromised,
+    you will have to move your funds to new wallet (with a new mnemonic seed). Therefore, it is best
+    that you backup your mnemonic seed by writing it down and storing it in <em>multiple</em> safe
+    and secure places.
+</p>
+<h2>Recover from Seed</h2>
+You already have a Monero Address and want to recover the transactions from the blockchain.<br/>
+Enter your Seed in the field "Mnemonic Seed". If you know the block number of the first
+transaction used for this address, enter it in the field "Restore Height" - leaving in blank will
+scan the <em>entire</em> blockchain for transactions belonging to your address.
+This takes a <em>long</em> time.
+
+<h2>Recover from Keys</h2>
+Instead of recovering from the mnemonic seed, you can recover using your keys.<br/>
+Enter your Monero Address in the field "Public Address" and fill out "View Key", "Spend Key"
+and optionally "Restore Height" with the appropriate values.
+
+<h2>View Only</h2>
+You just want to monitor incoming transactions to a wallet.<br/>
+Enter your Monero Address in the field "Public Address" and fill out the "View Key" and
+optionally "Restore Height" with the appropriate values leaving the "Spend Key" blank.

+This key is required for creating a view-only wallet or for recovering from keys.

+<h2>Spend Key</h2>
