+# Contributing
+
+Thank you for your interest in FINAL CUT!
+
+We welcome contributions of all kinds, including patches to code and 
+documentation, bug reports, or just neat feedback. If you ever think that 
+something could be better or different, please give us feedback on it. Do 
+you have problems with FINAL CUT, or are you looking for support in using 
+the library in your project? Feel free to open a new issue if there is not 
+already one on your topic. If you have problems with an application that 
+uses FINAL CUT and have no idea of the cause, please contact the author 
+first.
+
+Github hosts the source code of FINAL CUT. You can make a local copy from 
+the repository using git clone:
+
+```bash
+> git clone git://github.com/gansm/finalcut.git
+```
+
+
+## Submitting patches
+
+The FINAL CUT project accepts both 
+[GitHub pull requests](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request) 
+and patches that reach me via other channels. GitHub pull requests are 
+preferred. Please follow our [coding style](doc/coding-style.txt) standard.
+
+
+### Explain your work
+
+When submitting a patch, you should include a description of the problem 
+you are trying to solve, how you solved it, and why you chose the solution 
+you implemented. When you submit a bug fix, it is often helpful to include 
+a reproducible description for the problem in your explanation. Important 
+would be instructions on how to test the error and verify its elimination.
+
+
+### Test your code
+
+Run the FINAL CUT unit tests if you have installed 
+[CppUnit](https://freedesktop.org/wiki/Software/cppunit/). 
+Proceed as follows:
+
+The easy way
+
+```bash
+> make distclean
+> ./build.sh unit-test
+```
+
+or
+
+```bash
+> make distclean
+> ./configure --prefix=/usr CXXFLAGS="-g -O0 -DDEBUG -DUNIT_TEST" --with-unit-test
+> make test
+```
+
+If you have created uncovered code, I would be very grateful for 
+complementary test code in the existing unit tests.
+
+
+## Issue Tracking
+
+We currently use the 
+[issue tracker on Github](https://github.com/gansm/finalcut/issues).
+
+
+## How to help
+
+### What FINAL CUT needs
+
+* We want your feedback, your opinion, your advice, and to hear what you 
+think!
+* Help make FINAL CUT better known. Tell others about this project. A large 
+user base also means a better and more stable codebase.
+* Help maintain and improve the library.
+* Write unit tests for untested code.
+
+### What would be helpful
+
+* **Improve documentation:** <br />
+Fix typos or grammar mistakes. Revise sections that need improvement or 
+add missing sections.
+* **Translations into other languages:** <br />
+For many people, reading the documentary in their native language will 
+certainly make getting started with FINAL CUT much easier and more 
+attractive.
+* **Better tests:** <br />
+High code coverage gives us a stable base that prevents breaking code due 
+to a small patch.
+* **Publication in repositories:** <br />
+Advocate for the inclusion of FINAL CUT in your preferred distribution.
+* **Support for other platforms:** <br />
+There are still platforms on which FINAL CUT is not yet executable.
+* **Do you like to help other people?** <br />
+Answer questions in open issues or help moderate discussion forums or 
+other communication channels.
+
+Please help us make the FINAL CUT widget toolkit the best library for 
+text-based user interfaces.

-### Description
+FINAL CUT is a C++ class library and widget toolkit with full [mouse](doc/mouse-control.md#title-bar-actions-on-mouse-clicks) support for creating a [text-based user interface](https://en.wikipedia.org/wiki/Text-based_user_interface). The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen.
-The FINAL CUT is a C++ class library and widget toolkit with full mouse support for creating a [text-based user interface](https://en.wikipedia.org/wiki/Text-based_user_interface). The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen.
 
 The structure of the Qt framework was originally the inspiration for the C++ class design of FINAL CUT. It provides common controls like dialog boxes, push buttons, check boxes, radio buttons, input lines, list boxes, status bars and so on.

+# Security policy
+
+## Dealing with security vulnerabilities
+
+There is no separate process for handling security vulnerabilities in FINAL CUT. Security vulnerabilities are fixed and published like all other bugs. Nevertheless, from the moment they are brought to our attention, we try to close them as soon as possible.
+
+## Reporting a security vulnerability
+
+Preferably report a vulnerability via email to "guru.mail" + "@" + "muenster.de" or open an issue in the GitHub repository, the latter meaning that you made the vulnerability public before it was fixed.
+
+If you already have a solution for the security problem, please submit a pull request.

+User Themes
+===========
+
+FINAL CUT supports color themes. That makes it possible to change the color 
+of all elements of a widget in the program. Also, you can adjust the color 
+palette to your preferences. If you want to switch back to the default 
+themes, you can always call the method `FApplication::setDefaultTheme()` 
+or `FApplication::setDarkTheme()` for the dark theme.
+
+
+Widget Color Theme
+------------------
+
+FINAL CUT uses a default color scheme that the user can override in a 
+derived class of `FWidgetColors`. All widget colors are redefined in the 
+constructor by the method `setColorTheme()`.
+
+```cpp
+class myWidgetColors final : public finalcut::FWidgetColors
+{
+  public:
+    myWidgetColors()
+    {
+      myWidgetColors::setColorTheme();
+    }
+
+    ~myWidgetColors() override
+    { }
+
+    finalcut::FString getClassName() const override
+    {
+      return "myWidgetColors";
+    }
+
+    void myWidgetColors() override
+    {
+      ...  // Color definitions
+    }
+};
+```
+
+For setting the widget colors, it is recommended to call the method 
+`FWidget::setColorTheme()` via the `FApplication` object to create a 
+new instance of the theme and assign it to the application.
+
+```cpp
+finalcut::FApplication app(argc, argv);
+app.setColorTheme<myWidgetColors>();
+```
+
+In the following example, we will create the `BeeColorTheme`. For this 
+purpose, we will first create an include file that can be easily included 
+later in your application.
+
+**File:** *widget-color-theme.h*

+Color Palette Theme
+-------------------
+
+FINAL CUT has four color tables for the 16 standard colors in the terminal. 
+These are a redefinition of the 16 ANSI colors. You can address the colors 
+via indexes values from 0 to 15. They correspond to the following colors:
+
+| Index  | Color name                     |
+|:------:|:-------------------------------|
+|    0   | finalcut::FColor::Black        |
+|    1   | finalcut::FColor::Blue         |
+|    2   | finalcut::FColor::Green        |
+|    3   | finalcut::FColor::Cyan         |
+|    4   | finalcut::FColor::Red          |
+|    5   | finalcut::FColor::Magenta      |
+|    6   | finalcut::FColor::Brown        |
+|    7   | finalcut::FColor::LightGray    |
+|    8   | finalcut::FColor::DarkGray     |
+|    9   | finalcut::FColor::LightBlue    |
+|   10   | finalcut::FColor::LightGreen   |
+|   11   | finalcut::FColor::LightCyan    |
+|   12   | finalcut::FColor::LightRed     |
+|   13   | finalcut::FColor::LightMagenta |
+|   14   | finalcut::FColor::Yellow       |
+|   15   | finalcut::FColor::White        |
+
+You can define your color as an 8-bit value based on its red, green, and 
+blue components. To create a color palette, create a derived class of 
+`FColorPalette`. The constructor gets as argument the function to set 
+a palette color. This function must have the following structure:
+
+```cpp
+setPalette(finalcut::FColor index, int red, int green, int blue);
+```
+
+A possible implementation could look as follows:
+
+```cpp
+class myColorPalette final : public finalcut::FColorPalette
+{
+  public:
+    explicit myColorPalette (const FSetPalette& f)
+      : FColorPalette(f)
+    { }
+
+    ~myColorPalette()
+    { }
+
+    finalcut::FString getClassName() const override
+    {
+      return "myColorPalette";
+    }
+
+    void setColorPalette() override
+    {
+      ...  // Palette definitions
+    }
+
+    void resetColorPalette() override
+    {
+      setVGAdefaultPalette();
+    }
+};
+```
+To set the colors of a palette theme, you should use the method 
+`FTerm::setColorPaletteTheme()`. This method creates a new instance and 
+saves it in the `FTerm` object.
+
+```cpp
+finalcut::FTerm::setColorPaletteTheme<myColorPalette>();
+```
+The standard VGA palette is part of the `FColorPalette` class. To set it, 
+use the method `setVGAdefaultPalette()`. You can use it to reset the color 
+palette of terminals that cannot reset to default values with escape 
+sequences.
+<figure class="image">
+  <img src="user-theme-vga-palette.svg" alt="VGA palette">
+  <figcaption>Figure 1.  VGA palette</figcaption>
+</figure>
+<br /><br />
+
+The FINAL CUT eight-color palette `default8ColorPalette` is optimized for 
+the eight-color widget theme `default8ColorTheme`. It is for terminals 
+that cannot display more than eight colors.
+<figure class="image">
+  <img src="user-theme-fc8-palette.svg" alt="FINAL CUT 8-color palette">
+  <figcaption>Figure 2.  FINAL CUT 8-color palette</figcaption>
+</figure>
+<br /><br />
+
+The FINAL CUT palette `default16ColorPalette` is the default 16-color 
+palette. It is optimized for the widget color theme `default16ColorTheme`.
+<figure class="image">
+  <img src="user-theme-fc16-palette.svg" alt="FINAL CUT 16-color palette">
+  <figcaption>Figure 3.  FINAL CUT 16-color palette</figcaption>
+</figure>
+<br /><br />
+
+The second 16-color palette in FINAL CUT is for the dark theme. It was 
+adjusted for the widget color themes `default8ColorDarkTheme` and 
+`default16ColorDarkTheme`.
+<figure class="image">
+  <img src="user-theme-fc16-dark-palette.svg" alt="FINAL CUT 16-color dark palette">
+  <figcaption>Figure 4.  FINAL CUT 16-color dark palette</figcaption>
+</figure>
+<br /><br />
+
+In the following example, we want to create the palette them 
+`BeeColorPalette`. For this purpose, we generate an include file again, 
+in which we implement the new palette class.
+<figure class="image">
+  <img src="user-theme-bee-palette.svg" alt="Bee palette">

+Use of Themes
+-------------
+
+If you include the two include files above in your application, you can use 
+the widget color theme and the color palette theme. In the main function of 
+your application, the object instances of both classes are created and set.

+3C0h:  Attribute Controller: Address register
+bit 0-4  Address of data register to write to port 3C0h or read from port 3C1h
+         (Reads only on VGA).
+      5  If set screen output is enabled and the palette can not be modified,
+         if clear screen output is disabled and the palette can be modified.
+
+
+Port 3C0h is special in that it is both address and data-write register.
+Data reads happen from port 3C1h. An internal flip-flop remembers whether it
+is currently acting as address or data register.
+Accesses to the attribute controller must be separated by at least 250ns.
+Reading port 3dAh will reset the flip-flop to address mode.
+
+
+3C0h index 0-Fh  (r/W):  Attribute: Palette

+3C4h index  4  (r/W):  Sequencer: Memory Mode Register
+bit   0  Set if in an alphanumeric mode, clear in graphics modes.
+      1  Set if more than 64kbytes on the adapter.
+      2  Enables Odd/Even addressing mode if set. Odd/Even mode places all odd

+      3  (VGA Only)  If set address bit 0-1 selects video memory planes
+         (256 color mode), rather than the Map Mask and Read Map Select

+
+3C4h index 7 (R/W):  Sequencer Horizontal Character Counter Reset Register.
+                                                                   (VGA  Only)
+Note: Undocumented by IBM. May not be available in all clones.
+      A write to this register will cause the Horizontal Character Counter
+      to be held reset (=0) until a write happens to any of the Sequencer
+      registers index 0..6.
+      The Vertical Line counter is clocked by a signal derived from the
+      Horizontal Display Enable (which does not occur if the Horizontal
+      Character Counter is held reset).
+      Thus a write to index 7 during Vertical Retrace can stop the display
+      timing and allow software to start the next frame reasonably
+      synchronous to an external event.
+
+3C6h (R/W):  PEL Mask                                               (VGA Only)

+3C7h (R):  DAC State Register                                       (VGA Only)
+bit 0-1  0 indicates the DAC is in Read Mode and 3 indicates write mode.
+
+3C7h (W):  PEL Address Read Mode                                    (VGA Only)
+bit 0-7  The PEL data register (0..255) to be read from 3C9h.
+Note: After reading the 3 bytes at 3C9h this register will increment,
+      pointing to the next data register.
+
+3C8h (R/W):  PEL Address Write Mode                                 (VGA Only)
+bit 0-7  The PEL data register (0..255) to be written to 3C9h.
+Note: After writing the 3 bytes at 3C9h this register will increment, pointing
+      to the next data register.
+
+3C9h (R/W):  PEL Data Register                                      (VGA Only)
+bit 0-5  Color value
+Note:  Each read or write of this register will cycle through first the
+       registers for Red, Blue and Green, then increment the appropriate
+       address register, thus the entire palette can be loaded by writing 0 to
+       the PEL Address Write Mode register 3C8h and then writing all 768 bytes
+       of the palette to this register.
+
+3CAh (R):  Feature Control Register                                 (VGA Only)
+Bit   3  Vertical Sync Select. If set Vertical Sync to the monitor is the
+         logical OR of the vertical sync and the vertical display enable.
+Note: This register is written to port 3dAh and read from 3CAh.

+3CAh (W):  Graphics 2 Position                                      (EGA Only)
+bit 0-1  Select which bit planes should be controlled by Graphics Controller
+         #2. Always set to 1.
+
+3CCh (R):  Miscellaneous Output Register                            (VGA Only)
+bit   0  If set Color Emulation. Base Address=3Dxh else Mono Emulation. Base
+         Address=3Bxh.
+      1  Enable CPU Access to video memory if set
+    2-3  Clock Select. 0= 25MHz, 1= 28MHz, 2= Reserved
+      5  When in Odd/Even modes Select High 64k bank if set
+      6  Horizontal Sync Polarity. Negative if set
+      7  Vertical Sync Polarity. Negative if set
+         Bit 6-7 indicates the number of lines on the display:
+            0=Reserved, 1=400, 2=350, 3=480.
+Note: This register is written to port 3C2h and read from port 3CCh.
+
+3CCh (W):  Graphics 1 Position                                      (EGA Only)
+bit 0-1  Select which bit planes should be controlled by Graphics Controller
+         #1. Always set to 0.
+
+3CEh index  0  (r/W):  Graphics: Set/Reset Register
+bit   0  If in Write Mode 0 and bit 0 of 3CEh index 1 is set a write to
+         display memory will set all the bits in plane 0 of the byte to this
+         bit, if the corresponding bit is set in the Map Mask Register (3CEh
+         index 8).
+      1  Same for plane 1 and bit 1 of 3CEh index 1.
+      2  Same for plane 2 and bit 2 of 3CEh index 1.
+      3  Same for plane 3 and bit 3 of 3CEh index 1.
+
+3CEh index  1  (r/W):  Graphics: Enable Set/Reset Register
+bit   0  If set enables Set/reset of plane 0 in Write Mode 0.
+      1  Same for plane 1.
+      2  Same for plane 2.
+      3  Same for plane 3.
+
+3CEh index  2  (r/W):  Graphics: Color Compare Register
+bit 0-3  In Read Mode 1 each pixel at the address of the byte read is compared
+         to this color and the corresponding bit in the output set to 1 if
+         they match, 0 if not. The Color Don't Care Register (3CEh index 7)
+         can exclude bitplanes from the comparison.
+
+3CEh index  3  (r/W):  Graphics: Data Rotate
+bit 0-2  Number of positions to rotate data right before it is written to
+         display memory. Only active in Write Mode 0.
+    3-4  In Write Mode 2 this field controls the relation between the data
+         written from the CPU, the data latched from the previous read and the
+         data written to display memory:
+           0: CPU Data is written unmodified
+           1: CPU data is ANDed with the latched data
+           2: CPU data is ORed  with the latch data.
+           3: CPU data is XORed with the latched data.
+
+3CEh index  4  (r/W):  Graphics: Read Map Select Register
+bit 0-1  Number of the plane Read Mode 0 will read from.
+
+3CEh index  5  (r/W):  Graphics: Mode Register
+bit 0-1  Write Mode: Controls how data from the CPU is transformed before
+         being written to display memory:
+           0: Mode 0 works as a Read-Modify-Write operation.
+              First a read access loads the data latches of the EGA/VGA with
+              the value in video memory at the addressed location. Then a
+              write access will provide the destination address and the CPU
+              data byte. The data written is modified by the function code in
+              the Data Rotate register (3CEh index 3) as a function of the CPU
+              data and the latches, then data is rotated as specified by the
+              same register.
+           1: Mode 1 is used for video to video transfers.
+              A read access will load the data latches with the contents of
+              the addressed byte of video memory. A write access will write
+              the contents of the latches to the addressed byte. Thus a single
+              MOVSB instruction can copy all pixels in the source address byte
+              to the destination address.
+           2: Mode 2 writes a color to all pixels in the addressed byte of
+              video memory. Bit 0 of the CPU data is written to plane 0 et
+              cetera. Individual bits can be enabled or disabled through the
+              Bit Mask register (3CEh index 8).
+           3: (VGA Only) Mode 3 can be used to fill an area with a color and
+              pattern. The CPU data is rotated according to 3CEh index 3 bits
+              0-2 and anded with the Bit Mask Register (3CEh index 8). For
+              each bit in the result the corresponding pixel is set to the
+              color in the Set/Reset Register (3CEh index 0 bits 0-3) if the
+              bit is set and to the contents of the processor latch if the bit
+              is clear.
+      2  (EGA Only) Forces all outputs to a high impedance state if set.
+      3  Read Mode
+           0: Data is read from one of 4 bit planes depending on the Read Map
+              Select Register (3CEh index 4).
