         a low priority it can be hours before it is included on the blockchain. The default priority

+        <h1>Sending BTC</h1>
+        <h2>XMR.TO</h2>
+        <p>XMR.TO is a third party service which acts as an exchange from Monero to Bitcoin.
+        We use the XMR.TO API to integrate Bitcoin payments into Monerujo. Please check out
+        https://xmr.to and decide for yourself if this is something you want to use. The Monerujo
+        Team is not associated with XMR.TO and cannot help you with their service.</p>
+        <h2>XMR.TO Exchange Rate<h2>
+        <p>On the \"Amount\" screen you will be shown the current parameters of the XMR.TO service. These
+        include the current exchange rate as well as upper and lower BTC limits. Note that this
+        rate is not guaranteed at this point. You will also see
+        the amount up to which the BTC transaction will be executed instantly without waiting for
+        XMR confirmations (see the XMR.TO FAQ for more details). Please note, that XMR.TO does
+        not charge extra fees - how cool is that?</p>
+        <h2>XMR.TO Order<h2>
+        <p>On the \"Confirm\" screen, you will see the actual XMR.TO order. This order is valid for
+        a limited time - you may notice a countdown on the \"Spend\" button. The exchange rate may
+        be different to the indicative one shown on previous screens.</p>
+        <h2>XMR.TO Secret Key<h2>
+        <p>Since Monerujo only handles the Monero part of your transaction your XMR.TO secret key
+        can be used to track the Bitcoin part of your order on the XMR.TO homepage.</p>
+        <h2>XMR.TO Countdown!</h2>
+        <p>Once the countdown reaches zero, you need to get a new quote from XMR.TO by going back to the
+        previous step and then coming back to the \"Confirm\" screen.</p>
