+
+* Introduction
+
+Pamhyr2 is free and open source software (FOSS) graphical user
+interface (GUI) for 1D hydro-sedimentary modelling of rivers developed
+in Python (with version 3.8). It use PyQt at version 5 and matplotlib
+in version 3.4.1 or later for the user insterface (see
+{{{file(/requirements.txt)}}} for details). The architecture of
+project code follow the Qt Model/View architecture [fn:qt-arch] (see
+details in section [[Architecture]]). Pamhyr2 packages can be build
+manually (see section [[Building packages]]), but there are automatically
+build with the gitlab-ci (see the section [[Setup the CI
+environment]]). Documentation files are written with org-mode[fn:org],
+let see section [[Documentation files]]. Finally, to see the contribution
+rules, see the section [[How to contribute?]].

+** TODO View
+*** TODO UI file
+*** TODO Window class
+** TODO UndoCommand
+** TODO Table
+** TODO Plot
+** TODO Solver
+** TODO Unit tests
+** TODO The debug mode
+* TODO Build the project
+
+The project uses gitlab-ci runners to build packages, but it is possible
+to build packages manually.
+
+** Building packages
+
+If you need an hand made package, you can script available in
+{{{file(packages)}}} directory.
+
+*** GNU/Linux
+
+On GNU/Linux building GNU/Linux packages is easy, you just need python
+in version 3.8 must be installed with venv and pyinstaller packages
+(see Listing [[linux-env-deb]] for Debian and derived system). Finally,
+run the {{{file(linux.sh)}}} script (see Listing [[linux-pkg]]).
+
+#+NAME: linux-env-deb
+#+CAPTION: Install environment on GNU/Linux
+#+begin_src shell
+sudo apt install python3.8
+python3 -m pip install venv
+python3 -m pip install pyinstaller
+#+end_src
+
+#+NAME: linux-pkg
+#+CAPTION: Build GNU/Linux package
+#+begin_src shell
+cd packages
+./linux.sh
+#+end_src
+
+*** Windows
+
+To make the Windows packages you have two choice: If you use Windows
+you can use the script {{{file(packages/windows.bat)}}}, other else
+you can use the script {{{file(packages/wine.sh)}}}. Each script need
+a specific software environment.
+
+On windows, you needs python on version 3.8, pyinstaller and
+NSIS[fn:nsis] installed. On GNU/Linux you need wget, wine and
+winetricks installed.
+
+[fn:nsis] The NSIS web site: https://sourceforge.net/projects/nsis/
+
+** TODO Setup the CI environment
+* Documentation files
+
+This document and the user documentation are org files. This text file
+format is formatted so that it can be exported in different formats:
+PDF (with latex), ODT, HTML, etc. It was originally designed for the
+GNUEmacs[fn:emacs] text editor, but can be edited with any text editor. Here we
+take a look at the different features used in these documents.
+
+[fn:org] The org-mode website: https://orgmode.org/ (last access
+2023-09-15)
+[fn:emacs] The GNUEmacs project website: https://gnu.org/s/emacs/
+(last access 2023-09-15)
+
+** Org-mode
+*** Document structure
+
+Org uses the =*= character to define a new document section. To add a
+sub-section, you can add an additional =*= to the current section[fn::
+See document structure documentation:
+https://orgmode.org/org.html#Headlines (last access 2023-09-15)].
+
+#+BEGIN_EXAMPLE
+ * Top level headline
+ ** Second level
+ *** Third level
+     some text
+ *** Third level
+     more text
+ * Another top level headline
+#+END_EXAMPLE
+
+*** Format
+
+Org-mode is a markup file, using markup in the text to modify the
+appearance of a portion of text[fn:: See markup documentation:
+https://orgmode.org/org.html#Emphasis-and-Monospace (last access
+2023-09-15)].
+
+| Markup             | Results          |
+|--------------------+------------------|
+| =*Bolt*=           | *Bolt*           |
+| =/Italic/=         | /Italic/         |
+| =_underline_=      | _underline_      |
+| ==verbatim==       | =verbatim=       |
+| =~code~=           | ~code~           |
+| =+strike-through+= | +strike-through+ |
+
+*** Source code blocks
+
+You can add some code blocks[fn:: See org-mode documentation for
+source code: https://orgmode.org/org.html#Working-with-Source-Code
+(last access 2023-09-15)] in the document.
+
+Here is an example for python source code:
+#+BEGIN_EXAMPLE
+#+CAPTION: Get os type name in Python code
+#+begin_src python
+import os
+
+print(f"Document build on system: {os.name}")
+#+end_src
+#+END_EXAMPLE
+
+If you use GNUEmacs, it is also possible to run the code inside a
+block and export (or not) the reuslts in the document.
+
+#+OPTIONS: float:nil
+#+CAPTION: Get os type name in Python code
+#+begin_src python :python python3 :results output :exports both :noweb yes
+import os
+
+print(f"Document build on system: {os.name}")
+#+end_src
+
+#+RESULTS:
+: Document build on system: posix
+
+*** LaTeX
+
+If we export the file to PDF, org-mode use {{{latex}}}. So we can add
+some piece of {{{latex}}} into the document[fn:: See {{{latex}}} part
+in documentation: https://orgmode.org/org.html#Embedded-LaTeX (last
+access 2023-09-15)]. For exemple, we can add math formula like
+=$E=mc^2$= ($E=mc^2$) or =\[E=mc^2\]=:
+
+\[E=mc^2\]
+
+But we can also add every type of {{{latex}}}:
+
+#+BEGIN_EXAMPLE
+# Add latex in line
+#+LATEX: <my line of latex>
+
+# Add multiple line of LaTeX
+#+BEGIN_EXPORT latex
+<my latex here>
+#+END_EXPORT
+#+END_EXAMPLE
+
+It is also possible to add specific {{{latex}}} file header with
+=#+LATEX_HEADER=. In this document we use the file
+{{{file(doc/tools/latex.org)}}} for all {{{latex}}} headers.
+
+*** Macro
+
+In this document, we use a few macros[fn:: See marcos documentation
+https://orgmode.org/org.html#Macro-Replacement (last access
+2023-09-15)] to simplify writing. They allow you to define sequences
+of text to be replaced, so that the macro name is replaced by its
+value. They are defined in the {{{file(doc/tools/macro.org)}}}
+file. Once defined, they can be used in the document as follows:
+={{{<macro-name>}}}=. You can also have macros with arguments, in this
+case: ={{{<macro-name>(arg1,...)}}}=. Les macros peuvent aussi
+utiliser du code emacs-lisp.
+
+#+BEGIN_EXAMPLE
+# Exemple of macro définition
+
+#+MACRO: toto               tata
+#+MACRO: add                \(($1 + $2)\)
+#+MACRO: emacs-version      (eval (nth 2 (split-string (emacs-version))))
+#+END_EXAMPLE
+
+#+MACRO: toto               tata
+#+MACRO: add                \(($1 + $2)\)
+#+MACRO: emacs-version      (eval (nth 2 (split-string (emacs-version))))
+
+Macro apply:
+- Marco ={{{toto}}}=: {{{toto}}}
+- Marco ={{{add(x,y)}}}=: {{{add(x,y)}}}
+- Marco ={{{emacs-version}}}=: {{{emacs-version}}}
+
+*** Footnotes
+
+Footnote in org-mode is define with marker =[fn:...]=[fn:: Create
+footnotes in org-mode documentation
+https://orgmode.org/org.html#Creating-Footnotes (last access
+2023-09-15)]:
+#+BEGIN_EXAMPLE
+The Org website[fn:1] now looks a lot better than it used to.
+...
+[fn:1] The link is: https://orgmode.org
+#+END_EXAMPLE
+or:
+#+BEGIN_EXAMPLE
+The Org website[fn:: The link is: https://orgmode.org] now looks
+a lot better than it used to.
+...
+#+END_EXAMPLE
+
+*** References
+
+The references use the {{{latex}}} bibtex tools. The bib file is in
+{{{file(/doc/tools/ref.bib)}}} and use for developers and user
+documentation. In document, use ={{{cite(<name>)}}}= to cite a paper.
+
+** Export
+
+To export the files, a {{{file(build.sh)}}} script is available in the org
+files directories. On GNU/Linux system you can build the documentation
+PDF file with the command =./build.sh=. Texlive package must be
+installed, you can install only needed packages or all texlive
+packages, for example on Debian (and some derived system) use command
+Listing [[texlive-install]].
+
+#+NAME: texlive-install
+#+CAPTION: Installation command for texlive full on Debian system
+#+begin_src shell
+  sudo apt install texlive-full
+#+end_src
+
+Some org-mode configuration used in documentations files are define in
+=/doc/tools/=:
+- {{{file(PamhyrDoc.cls)}}}: The {{{latex}}} document class
+- {{{file(macro.org)}}}: Available macro
+- {{{file(latex.org)}}}: {{{latex}}} configutation for documentations
+  files
+- {{{file(setup.el)}}}: GNUEmacs configuration to build documentations
+- {{{file(ref.bib)}}}: Bibtex files for documentations files
