-Úvod
-----
-Tento dokument vás má za účel provést po aplikaci a pomoci vám se v ní
-zorientovat. Popis úkonů se přednostně vztahuje na operační systém Microsoft
-Windows, do jisté míry je však platný i pro jiné operační systémy.
-
-Získání aplikace
-----------------
-Nejnovější verzi aplikace je možné stáhnout na následující webové adrese:
-https://git.janouch.name/p/logdiag.
-
-[[gitea-download]]
-.Nabídka pro stahování na stráncách projektu
-image::gitea.png[]
-
-Až se ocitnete na webu, vyhledejte v záhlaví záložku s nápisem ``Releases'' a
-klepněte na ni. Zobrazí se přehled vydání a pod hlavičkami ``Downloads''
-související soubory ke stažení. Instalační soubor pro Microsoft Windows nese
-název ve stylu ``logdiag-__verze__-Windows-x86.exe''.
-
-Instalace
----------
-Proces instalace je velmi přímočarý. Po úvodní obrazovce je vyžadován souhlas s
-licencí. Pokud nerozumíte anglicky, její stručné shrnutí zní, že aplikaci smíte
-v nezměněné formě zcela volně používat a redistribuovat, ale nejsou vám
-poskytovány žádné záruky. Následuje výběr složky, do které chcete aplikaci
-nainstalovat, a složky pro umístění ve Start menu. V případě, že nenastala žádná
-náhlá chyba, už jen stačí potvrdit úspěšnou instalaci.
-
-WARNING: Pokud aplikaci instalujete do složky, kde se nachází již existující
-instalace, mohou nastat potíže. Ačkoliv je to možné, nepokoušejte se z těch
-samých příčin instalovat ani více kopií vedle sebe. Nejdříve stávající instalaci
-odstraňte, například pomocí zástupce umístěného ve Start menu.
-
-Operace s objekty
------------------
-
-////

-TODO: zkusit restrukturalizovat na:
-
-4. Operace s objekty
-   4.1 Základní operace
-       4.1.1 Výběr
-       4.1.2 Přesun
-       4.1.3 Odstranění
-   4.2 Značky
-       4.2.1 Vložení
-       4.2.2 Otáčení
-   4.3 Spojení
-       4.3.1 Tvorba
-
-////
-
-Každý diagram je tvořen z objektů, a s těmi se sdružují dále popsané operace.
-Budete-li chtít momentálně prováděnou operaci zrušit, můžete tak obvykle učinit
-stiskem klávesy Escape.
-
-Výběr objektů
-~~~~~~~~~~~~~
-Jednotlivé objekty můžete vybírat levým kliknutím myší. Ty se v reakci na to
-vyznačí červenou barvou. Chcete-li vybrat objektů více, držte během klikání
-stisknutou klávesu Shift.
-
-// XXX: nelze zarovnat obrázek na střed zároveň s caption
-[[select-objects]]
-.Výběr objektů v oblasti
-image::select-objects.png[]
-
-Alternativně můžete táhnout myší z volné oblasti diagramu do prostoru, viz
-<<select-objects>>. Vyberou se objekty obsažené ve vytvořeném obdélníku. Výběr
-lze zrušit klepnutím na prázdné místo.
-
-Přesun objektů
-~~~~~~~~~~~~~~
-Přesun objektů se provede tažením objektů myší na požadované místo. Pokud jsou
-tyto objekty součástí výběru, přesune se celý výběr. Ten lze též přesouvat
-pomocí kurzorových kláves.
-
-Odstranění objektů
-~~~~~~~~~~~~~~~~~~
-Objekty odstraníte stisknutím klávesy Delete, případně z menu aplikace.
-
-Vložení značky
-~~~~~~~~~~~~~~
-_Značky_ představují nejdůležitější druh objektů. Do diagramu je vložíte výběrem
-z nabídky značek umístěné po levé straně hlavního okna aplikace a přetažením
-myší do diagramu na požadované umístění.
-
-Otáčení značek
-~~~~~~~~~~~~~~
-Otočit značku vloženou do diagramu můžete přes pravé tlačítko myši.
-
-Propojení terminálů
-~~~~~~~~~~~~~~~~~~~
-_Terminálem_ se nazývá bod určený pro tvorbu spojení mezi značkami nebo jinými
-spojeními. Abyste z něj spojení vyvedli, nejdříve na něj najeďte kurzorem myši
-tak, aby se viditelně vyznačil kroužkem. Pak stiskněte levé tlačítko myši a
-přetáhněte kurzor myši na místo, kde chcete, aby spojení končilo.
-
-// XXX: nelze sloučit do jedné figure
-[[create-connection]]
-.Propojení terminálů dvou značek
-image:create-connection-begin.png[]
-&nbsp;...&nbsp;
-image:create-connection-end.png[]
-
-Časté problémy
---------------
-
-Nelze otevřít uložený diagram
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Při ukládání se ujistěte, že zadaný název souboru obsahuje příponu ``.ldd''. V
-opačném případě se nezobrazí v dialogu pro otevření diagramu. Pokud jste nějaký
-soubor již bez přípony uložili, napravíte to dodatečným přidáním přípony k jeho
-názvu.
-
-Jak můžu diagram vytisknout?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Současná verze aplikace není schopná přímo tisknout. Pro vytištění vytvořeného
-diagramu můžete klávesou PrintScreen sejmout snímek obrazovky, vložit jej
-například do aplikace Malování, oříznout požadovanou část a vytisknout ji z
-tohoto grafického editoru.
-
-Schází mi popisky
-~~~~~~~~~~~~~~~~~
-Obdobně jako v předchozím případě tato funkcionalita zatím neexistuje, ale je
-možné tento nedostatek obejít přes běžný grafický editor.

+s licencí. Pokud nerozumíte anglicky, její stručné shrnutí zní, že aplikaci
+smíte v nezměněné formě zcela volně používat a redistribuovat, ale nejsou vám
+poskytovány žádné záruky. Následuje výběr složky, do které chcete aplikaci
+nainstalovat, a složky pro umístění ve Start menu. V případě, že nenastala žádná
+náhlá chyba, už jen stačí potvrdit úspěšnou instalaci.
+
+<p><b>Pozor</b>: Pokud aplikaci instalujete do složky, kde se nachází již
+existující instalace, mohou nastat potíže. Ačkoliv je to možné, nepokoušejte se
+z těch samých příčin instalovat ani více kopií vedle sebe. Nejdříve stávající
+instalaci odstraňte, například pomocí zástupce umístěného ve Start menu.
+
+<h2>Operace s objekty</h2>
+<p>Každý diagram je tvořen z objektů, a s těmi se sdružují dále popsané operace.
+Budete-li chtít momentálně prováděnou operaci zrušit, můžete tak obvykle učinit
+stiskem klávesy Escape.

+
+<h3>Výběr objektů</h3>
+<p>Jednotlivé objekty můžete vybírat levým kliknutím myší. Ty se v reakci na to
+vyznačí červenou barvou. Chcete-li vybrat objektů více, držte během klikání
+stisknutou klávesu Shift.
+
+<p class="figure" id="select-objects">
+<img src="select-objects.png" alt="Výběr objektů">
+<br>Obrázek 2: Výběr objektů v oblasti
+
+<p>Alternativně můžete táhnout myší z volné oblasti diagramu do prostoru, viz
+<a href="#select-objects">Obrázek 2</a>. Vyberou se objekty obsažené
+ve vytvořeném obdélníku. Výběr lze zrušit klepnutím na prázdné místo.
+
+<h3>Přesun objektů</h3>
+<p>Přesun objektů se provede tažením objektů myší na požadované místo. Pokud
+jsou tyto objekty součástí výběru, přesune se celý výběr. Ten lze též přesouvat
+pomocí kurzorových kláves.
+
+<h3>Odstranění objektů</h3>
+<p>Objekty odstraníte stisknutím klávesy Delete, případně z menu aplikace.
+
+<h3>Vložení značky</h3>
+<p><i>Značky</i> představují nejdůležitější druh objektů. Do diagramu je vložíte
+výběrem z nabídky značek umístěné po levé straně hlavního okna aplikace
+a přetažením myší do diagramu na požadované umístění.
+
+<h3>Otáčení značek</h3>
+<p>Otočit značku vloženou do diagramu můžete přes pravé tlačítko myši.
+
+<h3>Propojení terminálů</h3>
+<p><i>Terminálem</i> se nazývá bod určený pro tvorbu spojení mezi značkami nebo
+jinými spojeními. Abyste z něj spojení vyvedli, nejdříve na něj najeďte kurzorem
+myši tak, aby se viditelně vyznačil kroužkem. Pak stiskněte levé tlačítko myši
+a přetáhněte kurzor myši na místo, kde chcete, aby spojení končilo.

+
+<h2>Časté problémy</h2>
+<h3>Nelze otevřít uložený diagram</h3>
+<p>Při ukládání se ujistěte, že zadaný název souboru obsahuje příponu
+<q>.ldd</q>. V opačném případě se nezobrazí v dialogu pro otevření diagramu.
+Pokud jste nějaký soubor již bez přípony uložili, napravíte to dodatečným
+přidáním přípony k jeho názvu.
+
+<h3>Schází mi popisky</h3>
+<p>Tato funkcionalita zatím neexistuje, ale je možné tento nedostatek obejít
+buď sejmutím snímku obrazovky klávesou PrintScreen a jeho vložením například
+do aplikace Malování, nebo obdobně doplněním vašich textů do <q>vytištěného</q>
+PDF souboru.

-
-Introduction
-------------
-This document will guide you through the application and help to familiarize you
-with it. The description of tasks mainly targets the Microsoft Windows
-operating system, though it's also valid for other operating systems to
-a certain extent.
-
-Getting the application
------------------------
-Download the newest version of the application at the following web address:
-https://git.janouch.name/p/logdiag.
-
-[[gitea-download]]
-.The download menu on the project site
-image::gitea.png[]
-
-While on the web, look for a tab entitled ``Releases'' and click on it. A list
-of versions will appear with files for download listed under ``Downloads''
-headings.  The installation file for Microsoft Windows is named in the style of
-``logdiag-__version__-Windows-x86.exe''.
-
-Installation
-------------
-The installation process is quite straight-forward. After the initial screen a
-license agreement is required. Next, choose a folder in which to install the
-application and another one for placement in the Start menu. So long as no
-unexpected errors have occurred, all that's left is confirming a successful
-installation.
-
-WARNING: If the application is installed into a folder where a previous
-installation is already located, problems may arise. Although it is possible to
-do so, don't try to install multiple copies parallely either, for the same
-reasons. Remove the current installation first, for example by using the
-shortcut located in the Start menu.

-Operations with objects

-
-Each diagram consists of objects, and these are accompanied by the operations
-described below. To cancel any current operation, press the Escape key.
-
-Selecting objects
-~~~~~~~~~~~~~~~~~
-Select single objects by left-clicking on them. They will get highlighted with
-red color in reaction to this. To select multiple objects, hold the Shift key
-while clicking.
-
-// XXX: nelze zarovnat obrázek na střed zároveň s caption
-[[select-objects]]
-.Selecting objects inside an area
-image::select-objects.png[]
-
-Alternatively drag the mouse from free space within the diagram into the area,
-see <<select-objects>>. Objects contained in this rectangle will be
-selected. The selection may later be dismissed by just clicking into free space.
-
-Moving objects
-~~~~~~~~~~~~~~
-Moving of objects is done by dragging them with the mouse onto the desired
-place. If these objects form a part of the current selection, the whole
-selection is moved. The selection may also be moved using cursor keys.
-
-Removing objects
-~~~~~~~~~~~~~~~~
-Remove objects either by pressing the Delete key or from the application menu.
-
-Inserting symbols
-~~~~~~~~~~~~~~~~~
-_Symbols_ constitute the most important kind of objects. Insert them into the
-diagram by choosing one from the symbol menu located on the left side of the
-main application window and dragging it onto the diagram where you want the
-symbol to be placed.
-
-Rotating symbols
-~~~~~~~~~~~~~~~~
-Rotate a symbol inserted into the diagram by right-clicking on it.
-
-Connecting terminals
-~~~~~~~~~~~~~~~~~~~~
-A point intended for creation of connections between symbols or other
-connections is called a _terminal_. To lead a connection out of it, first
-hover it with the mouse pointer, so it gets visibly highlighted with a circle.
-Then press the left mouse button and drag the pointer onto the place where you
-want the connection to end.
-
-// XXX: nelze sloučit do jedné figure
-[[create-connection]]
-.Interconnecting terminals of two symbols
-image:create-connection-begin.png[]
-&nbsp;...&nbsp;
-image:create-connection-end.png[]
-
-Frequent problems
------------------
-
-Can't open a saved diagram
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-When saving, ensure that the filename you've typed in contains the ``.ldd''
-suffix. If not, it won't show up in the dialog for opening diagrams. In case
-you've already saved a file without an extension, you may fix this situation by
-adding the suffix to its name.
-
-How do I print a diagram?
-~~~~~~~~~~~~~~~~~~~~~~~~~
-The current version of application is not able to print directly. To print out a
-created diagram, you may use the PrintScreen key to capture a screenshot, then
-insert it to, for example, Paint, and print it from inside the graphics editor.
-
-I miss labels
-~~~~~~~~~~~~~
-Similarly to the previous case, this functionality doesn't exist yet, but it is
-possible to get around this limitation using a graphics editor.
