-<div class="paragraph"><p><span class="blue"><em>Version 1.0, March 2016</em></span></p></div>
-<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em>, advanced dive logging software with
-extensive infrastructure to describe, organize, interpret and print scuba
-and free dives. <em>Subsurface</em> offers many advantages over other similar
-software solutions, including compatibility with Windows, Mac-OS/X, Linux (many
-distributions) and Android (iOS under development). In addition, <em>Subsurface</em> is
-open-source software that allows downloading dive
-information from most dive computers.</p></div>
-<div class="sect1">
-<h2 id="_introducing_subsurface_mobile">1. Introducing Subsurface-mobile</h2>
-<div class="sectionbody">
-<div class="paragraph"><p><em>Subsurface-mobile</em> is an extension of <em>Subsurface</em> on laptop and
-tabletop computers. It runs on Android smartphone and tablet devices and is a
-tool for viewing or sharing dive information at dive sites where a larger
-computer is not useful. <em>Subsurface-mobile</em> also allows
-the gathering of GPS locations where dives are performed.</p></div>
-<div class="paragraph"><p>A version of <em>Subsurface-mobile</em> for iOS is under development but not yet
-ready for testing.</p></div>
-<div class="paragraph"><p>While <em>Subsurface-mobile</em> allows one to enter and save dive information
-using an Android device, users of <em>Subsurface-mobile</em> typically use the
-mobile app as an extension of the laptop/desktop version of <em>Subsurface</em>.
-This allows the storage of dive logs on the Internet and which
-can be shared by the Android version as well as the desktop version.
-While the desktop version of <em>Subsurface</em> shows much more detailed information
-for each dive, the mobile version allows one to have a more accessible dive log
-on a dive trip, useful for proving dive experience to dive shops or to review
-previous dives.</p></div>
-<div class="paragraph"><p><em>Subsurface-mobile</em> allows one to:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Download existing dive log information from the Internet.
-</p>
-</li>
-<li>
-<p>
-View this information on an Android device.
-</p>
-</li>
-<li>
-<p>
-Edit many of the dive log data fields, e.g. divemaster, buddy,
- equipment or notes about a dive.
-</p>
-</li>
-<li>
-<p>
-Create and add new dive records to one&#8217;s dive log.
-</p>
-</li>
-<li>
-<p>
-Store the updated dive log on the Internet.
-</p>
-</li>
-<li>
-<p>
-Record, store and apply GPS positions of dives.
-</p>
-</li>
-<li>
-<p>
-View the localities of recorded GPS positions and of dives
- on a map.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>These items are discussed in greater detail in the following text.
-What <em>Subsurface-mobile</em> does not support (at this time) is downloading
-dive data directly from a dive computer. That still has to happen with
-<em>Subsurface</em> on a desktop or laptop computer. We are investigating ways
-to support downloading from a subset of the supported dive computers on
-Android devices, but this is not yet ready for testing.</p></div>
-</div>
-</div>
-<div class="sect1">
-<h2 id="_installing_em_subsurface_mobile_em_on_an_android_device">2. Installing <em>Subsurface-mobile</em> on an Android device</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>Find <em>Subsurface-mobile</em> in the <em>Google
-Play Store</em>. Search for <em>Subsurface-mobile</em> and install it.</p></div>
-</div>
-</div>
-<div class="sect1">
-<h2 id="_using_em_subsurface_mobile_em_for_the_first_time">3. Using <em>Subsurface-mobile</em> for the first time</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>Upon starting <em>Subsurface-mobile</em> for the first time, a Subsurface
-splash screen is shown while the program loads. On some devices this
-may take several seconds. After loading, the <em>Cloud Credentials screen</em> appears
-(see image below).</p></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="mobile-images/landingscreen.jpg" alt="FIGURE: Mobile landing screen" />
-</div>
-</div>
-<div class="paragraph"><p>Since <em>Subsurface</em> is largely dependent on a dive log saved on the Internet,
-provide a user-ID and password for access to the <em>Subsurface Cloud</em>. These
-credentials are obtained by opening the desktop version of <em>Subsurface</em> and
-by clicking <em>File &#8594; Preferences &#8594; Network</em>, explained in detail in the
-user manual for the <em>Subsurface</em> desktop version. Once the account has
-been created and verified using the desktop version one can use <em>Subsurface-mobile</em>.</p></div>
-<div class="paragraph"><p>When entering a password, it is possible to check
-a checkbox that enables the text of the password to be shown. Checking the
-check box labelled "Remember" allows <em>Susburface-mobile</em> to keep the
-credentials for subsequent logins (see image above).
-Having entered the credentials, tap the disk icon at the bottom of the screen.
-<em>Subsurface-mobile</em> attempts to download the existing dive log from the_Subsurface_ cloud
-server. Appropriate messages are shown onscreen. Finally
-a list of dives are shown.</p></div>

-<div class="sect1">
-<h2 id="_local_copy_of_the_dive_log_and_synchronisation_with_internet">4. Local copy of the dive log and synchronisation with Internet</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>Once the dive
-list has been downloaded from the Internet, <em>Subsurface-mobile</em> keeps a local
-copy on the mobile device. This means that, if there is no Internet connection
-at a dive site, one can still access the local copy and view and manipulate
-dive information. If there is Internet connectivity, <em>Subsurface-mobile</em> accesses
-the Internet-based dive log to verify that the local copy is still the
-same as the Internet-stored copy. If not, the local copy and the copy on
-the server are synchronised.</p></div>
-</div>
-</div>
-<div class="sect1">
-<h2 id="_a_few_remarks_about_the_user_interface">5. A Few Remarks About The User Interface</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>At the bottom of many Subsurface-mobile screens is a round button that provides for
-several actions and which allows the selection of the main affirmative action
-(see image above and image below).
-On Android devices, use the Android Back
-button for "cancel", "discard" or "back" actions. For example, when
-editing dive information, tapping the action button saves the changes, the
-Android back button can be used to cancel the edit without saving changes.</p></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="mobile-images/actionbutton.jpg" alt="FIGURE: Action Button" />
-</div>
-</div>
-<div class="paragraph"><p>Instead of the more traditional "hamburger" menu button in the top left or
-right corner of the screen to open menus, <em>Subsurface-mobile</em> uses a
-different user interaction philosophy based on the Kirigami framework
-developed by the Plasma developers. To open the main menu one has
-three options:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Tap on the right-arrow symbol in the lower left corner of the screen
- (easy to reach for hand held devices)
-</p>
-</li>
-<li>
-<p>
-Swipe towards the right across the left edge of the screen
-</p>
-</li>
-<li>
-<p>
-Drag the action button visible on most screens with the main action to
- the right
-</p>
-</li>
-</ul></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="mobile-images/menu.jpg" alt="FIGURE: Dive management subpanel" />
-</div>
-</div>
-<div class="paragraph"><p>The images above indicate some of the important features of the menu system.
-On the left is the main menu that is activated as described above. In the middle is
-the menu that opens if one taps the <em>GPS</em> option on the main menu. On the right is
-the menu that opens if one taps the <em>Manage Dives</em> option on the main menu.</p></div>
-<div class="paragraph"><p>Similarly, the context menu (currently only available on the dive details screen) can be
-opened one of these three ways:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Tap on the left-arrow symbol in the lower right corner of the screen
-</p>
-</li>
-<li>
-<p>
-Swipe to the left across the right edge of the screen
-</p>
-</li>

-<p>
-Drag the action button to the left

-dive list. While the dive list is loading from the cloud,
-a message appears at the bottom of the screen, indicating that the cloud is
-being accessed (see image on left, below). Once the list is loaded one can scroll up and down.
-Tapping a dive on the list brings up a display of <em>Details View</em> for that dive (see image on right below).

-one taps the handle (the three horisontal stripes on the right, see image on left, below) and
-then drags the specific item to the left (image on right, below). This exposes two
-options. Tapping the dustbin deletes this particular GPS location. Tapping the
-teardrop-shaped icon (actually a Google Maps pin) opens up Google Maps with a pin
-indicating the exact map position of the GPS record being viewed. The two above

-<div class="paragraph"><p>Assuming that all the dives have been entered into the dive log or have
-been downloaded from the <em>Subsurface</em> cloud, one can apply the GPS positions to
-these dives. GPS positions can therefore only be applied to dives in the dive list.
-From the GPS subpanel, tap <em>Apply GPS fixes</em>. The dive list contains the start
-and end times of each dive. Now, <em>Subsurface-mobile</em> applies the first
-GPS position that falls within the dive period of each dive. This results
-in a GPS position for each dive that is saved as part of the dive list.</p></div>

+<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em>, advanced dive logging software with
+extensive infrastructure to describe, organize, interpret and print scuba
+and free dives. <em>Subsurface</em> offers many advantages over other similar
+software solutions, including compatibility with Windows, Mac-OS/X, Linux (many
+distributions) and Android (iOS under development). In addition, <em>Subsurface</em> is
+open-source software that allows downloading dive
+information from most dive computers.</p></div>
+<div class="sect1">
+<h2 id="_introducing_subsurface_mobile">1. Introducing Subsurface-mobile</h2>
+<div class="sectionbody">
+<div class="paragraph"><p><em>Subsurface-mobile</em> is an extension of <em>Subsurface</em> on laptop and
+tabletop computers. It runs on Android smartphone and tablet devices and is a
+tool for viewing or sharing dive information at dive sites where a larger
+computer is not useful. <em>Subsurface-mobile</em> also allows
+the gathering of GPS locations where dives are performed.</p></div>
+<div class="paragraph"><p>A version of <em>Subsurface-mobile</em> for iOS is under development but not yet
+ready for testing.</p></div>
+<div class="paragraph"><p>While <em>Subsurface-mobile</em> allows one to enter and save dive information
+using an Android device, users of <em>Subsurface-mobile</em> typically use the
+mobile app as an extension of the laptop/desktop version of <em>Subsurface</em>.
+This allows the storage of dive logs on the Internet and which
+can be shared by the Android version as well as the desktop version.
+While the desktop version of <em>Subsurface</em> shows much more detailed information
+for each dive, the mobile version allows one to have a more accessible dive log
+on a dive trip, useful for proving dive experience to dive shops or to review
+previous dives.</p></div>
+<div class="paragraph"><p><em>Subsurface-mobile</em> allows one to:</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+Download existing dive log information from the Internet.
+</p>
+</li>
+<li>
+<p>
+View this information on an Android device.
+</p>
+</li>
+<li>
+<p>
+Edit many of the dive log data fields, e.g. divemaster, buddy,
+ equipment or notes about a dive.
+</p>
+</li>
+<li>
+<p>
+Create and add new dive records to one&#8217;s dive log.
+</p>
+</li>
+<li>
+<p>
+Store the updated dive log on the Internet.
+</p>
+</li>
+<li>
+<p>
+Record, store and apply GPS positions of dives.
+</p>
+</li>
+<li>
+<p>
+View the localities of recorded GPS positions and of dives
+ on a map.
+</p>
+</li>
+</ul></div>
+<div class="paragraph"><p>These items are discussed in greater detail in the following text.
+What <em>Subsurface-mobile</em> does not support (at this time) is downloading
+dive data directly from a dive computer. That still has to happen with
+<em>Subsurface</em> on a desktop or laptop computer. We are investigating ways
+to support downloading from a subset of the supported dive computers on
+Android devices, but this is not yet ready for testing.</p></div>

+<div class="sect1">
+<h2 id="_using_em_subsurface_mobile_em_for_the_first_time">3. Using <em>Subsurface-mobile</em> for the first time</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>Upon starting <em>Subsurface-mobile</em> for the first time, a Subsurface
+splash screen is shown while the program loads. On some devices this
+may take several seconds. After loading, the <em>Cloud Credentials screen</em> appears
+(see image below).</p></div>
+<div class="imageblock" style="text-align:center;">
+<div class="content">
+<img src="mobile-images/landingscreen.jpg" alt="FIGURE: Mobile landing screen" />
+</div>
+</div>
+<div class="paragraph"><p>Since <em>Subsurface</em> is largely dependent on a dive log saved on the Internet,
+provide a user-ID and password for access to the <em>Subsurface Cloud</em>. These
+credentials are obtained by opening the desktop version of <em>Subsurface</em> and
+by clicking <em>File &#8594; Preferences &#8594; Network</em>, explained in detail in the
+user manual for the <em>Subsurface</em> desktop version. Once the account has
+been created and verified using the desktop version one can use <em>Subsurface-mobile</em>.</p></div>
+<div class="paragraph"><p>When entering a password, it is possible to check
+a checkbox that enables the text of the password to be shown. Checking the
+check box labelled "Remember" allows <em>Susburface-mobile</em> to keep the
+credentials for subsequent logins (see image above).
+Having entered the credentials, tap the disk icon at the bottom of the screen.
+<em>Subsurface-mobile</em> attempts to download the existing dive log from the_Subsurface_ cloud
+server. Appropriate messages are shown onscreen. Finally
+a list of dives are shown.</p></div>

+<h2 id="_local_copy_of_the_dive_log_and_synchronisation_with_internet">4. Local copy of the dive log and synchronisation with Internet</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>Once the dive
+list has been downloaded from the Internet, <em>Subsurface-mobile</em> keeps a local
+copy on the mobile device. This means that, if there is no Internet connection
+at a dive site, one can still access the local copy and view and manipulate
+dive information. If there is Internet connectivity, <em>Subsurface-mobile</em> accesses
+the Internet-based dive log to verify that the local copy is still the
+same as the Internet-stored copy. If not, the local copy and the copy on
+the server are synchronised.</p></div>

+<div class="sect1">
+<h2 id="_a_few_remarks_about_the_user_interface">5. A Few Remarks About The User Interface</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>At the bottom of many Subsurface-mobile screens is a round button that provides for
+several actions and which allows the selection of the main affirmative action
+(see image above and image below).
+On Android devices, use the Android Back
+button for "cancel", "discard" or "back" actions. For example, when
+editing dive information, tapping the action button saves the changes, the
+Android back button can be used to cancel the edit without saving changes.</p></div>
+<div class="imageblock" style="text-align:center;">
+<div class="content">
+<img src="mobile-images/actionbutton.jpg" alt="FIGURE: Action Button" />
+</div>
+</div>
+<div class="paragraph"><p>Instead of the more traditional "hamburger" menu button in the top left or
+right corner of the screen to open menus, <em>Subsurface-mobile</em> uses a
+different user interaction philosophy based on the Kirigami framework
+developed by the Plasma developers. To open the main menu one has
+three options:</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+Tap on the right-arrow symbol in the lower left corner of the screen
+ (easy to reach for hand held devices)
+</p>
+</li>
+<li>
+<p>
+Swipe towards the right across the left edge of the screen
+</p>
+</li>
+<li>
+<p>
+Drag the action button visible on most screens with the main action to
+ the right
+</p>
+</li>
+</ul></div>

+<div class="content">
+<img src="mobile-images/menu.jpg" alt="FIGURE: Dive management subpanel" />
+</div>
+</div>
+<div class="paragraph"><p>The images above indicate some of the important features of the menu system.
+On the left is the main menu that is activated as described above. In the middle is
+the menu that opens if one taps the <em>GPS</em> option on the main menu. On the right is
+the menu that opens if one taps the <em>Manage Dives</em> option on the main menu.</p></div>
+<div class="paragraph"><p>Similarly, the context menu (currently only available on the dive details screen) can be
+opened one of these three ways:</p></div>
+<div class="ulist"><ul>
+<li>
+<p>
+Tap on the left-arrow symbol in the lower right corner of the screen
+</p>
+</li>
+<li>

+<h2 id="_viewing_the_dive_list">6. Viewing the Dive List</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>Most of the actions of <em>Subsurface-mobile</em> center around the dives on the
+dive list. While the dive list is loading from the cloud,
+a message appears at the bottom of the screen, indicating that the cloud is
+being accessed (see image on left, below). Once the list is loaded one can scroll up and down.
+Tapping a dive on the list brings up a display of <em>Details View</em> for that dive (see image on right below).
+This includes the dive profile as well as additional information and notes.</p></div>
+<div class="imageblock" style="text-align:center;">
+<div class="content">
+<img src="mobile-images/divelist.jpg" alt="FIGURE: Dive list screen" />
+</div>
+</div>
+<div class="paragraph"><p>One can view other dives by swiping the <em>Details view</em> to the right (for the
+previous dive) or to the left (following dive).</p></div>

+<div class="sect1">
+<h2 id="_editing_dive_details">7. Editing dive details.</h2>
+<div class="sectionbody">
+<div class="paragraph"><p>At the bottom of the dive details screen the <em>Action Button</em> contains a pencil (image on right, above).
+Tapping the button brings up a panel with edit boxes that allows one to
+change the existing dive information, e.g. adding text to the dive notes
+or changing the names or values of some of the information (see image below).
+It may be necessary to scroll the window to access all the information.
+At the bottom of the edit screen is a <em>Save</em> action button. Tap this to save
+the new information. Having saved the data, the dive list screen is
+updated and shown. To cancel any edits, tap the Android Back Button.</p></div>

+<div class="sectionbody">
+<div class="paragraph"><p>It is also possible to add an additional dive to the existing dive list. On the
+main menu tap <em>Manage dives &#8594; Add dive manually</em>. This opens a screen that is
+identical to the editing screen discussed above. When a dive is added manually, one
+cannot directly add a dive profile from a dive computer. However, if one does not use a
+dive computer, the duration, depth and several other bits of information about
+the new dive can be entered. The <em>Action button</em> at the bottom of the screen
+contains a disk symbol. Tap this to save the new dive. To cancel any edits, tap the Android Back Button.
+The left-hand image below shows a screenshot of a dive being created and the right-hand image shows

+<div class="sectionbody">
+<div class="paragraph"><p>A central part of <em>Subsurface-mobile</em> is the ability to store the dive
+log using the <em>Subsurface</em> cloud storage.
+This provides security against loss or damage to the dive information caintained in a local copy of
+the dive log and allows the desktop version of <em>Subsurface</em> to
+access changes made using the mobile device. This ability is accessed
+throug the main menu (by dragging the Action Button to the right, or
+alternatively tap the right angle button at the bottom left of the screen).
