+* **[ru.auroraos.DocumentConverter.pro](application/ru.auroraos.DocumentConverter.pro)** file
+describes the project that contains two subprojects where the first is responsible
+for building the libreoffice, and the second describes the structure of the application for
+the qmake build system.
+* **[upstream](upstream)** directory contains source code LibreOffice (git submodule).
+* **[tarballs](tarballs)** directory of dependencies in the form of archives necessary for the build LibreOffice.
+* **[libs](libs)** directory of dependencies in the form of source codes necessary for the build LibreOffice.
+
+## Compatibility
+
+The project is compatible with all the current versions of the Aurora OS.
+
+## Project Building
+
+### Clear building
+
+1. Make sure that you have 32 GB of RAM and SDK with docker (don't use VB for building this example).
+1. Open a terminal or command prompt.
+1. Navigate to the directory that contains your Git repository.
+1. Execute the command "git lfs pull" to download any files tracked by LFS.
+1. Execute the command "git submodule update --init --recursive" to update and initialize submodules in the repository.
+1. Execute the command "mb2 -t AuroraOS-5.0.0.60-base-armv7hl build-init" to initialize the build environment.
+1. Execute the command "mb2 -t AuroraOS-5.0.0.60-base-armv7hl prepare" to apply the patches needed for the build.
+1. Execute the command "mb2 -t AuroraOS-5.0.0.60-base-armv7hl build" to start building the package.
+1. Execute the command to sign the rpm-package:
+```
+sfdk engine exec rpmsign-external sign  \
+    --key absolute/path/to/key/file.pem \
+    --cert absolute/path/to/cert/file.pem \
+      absolute/path/to/rpm/package.rpm
+```
+The target rpm-package is in the RPMS directory of the project.
+
+### Solutions of possible problems
+
+If building is failed with the next error
+```
+ aclocal -I <path/to>/DocumentConverter/upstream/m4
+autom4te: error: need GNU m4 1.4 or later: /usr/bin/m4
+aclocal: error: echo failed with exit status: 1
+```
+then enter into the target and install the m4 dependency manually.
+
+### Repeated building for another target
+
+The build is run in the same directory as the application sources so it's necessary to delete the previous building results before a new build for another target.
+
+Run the next commands from the project root directory:
+1. `rm -fr libs_build`
+2. `rm -fr upstream/workdir`
+3. `rm -f application/Makefile`
+4. `cd libs/liblangtag && make distclean`

+        * Каталог **[src](application/src)** содержит исходный код на C++.
+          * Файл **[main.cpp](application/src/main.cpp)** является точкой входа в приложение.
+    * Файл **[ru.auroraos.DocumentConverter.desktop](application/ru.auroraos.DocumentConverter.desktop)** 
+        определяет отображение и параметры запуска приложения.

+* Каталог **[tarballs](tarballs)** содержит зависимости в форме архивов, необходимые для сборки библиотеки LibreOffice.
+* Каталог **[libs](libs)** содержит зависимости в форме исходного кода, необходимые для сборки библиотеки LibreOffice.
+
+## Совместимость
+
+Проект совместим с актуальными версиями ОС Аврора.
+
+## Сборка проекта
+
+### Чистовая сборка
+
+1. Убедитесь, что у вас есть 32 ГБ оперативной памяти и SDK с docker (не используйте VB для сборки этого примера).
+1. Откройте терминал или командную строку.
+1. Перейдите в каталог, содержащий ваш Git-репозиторий.
+1. Выполните команду "git lfs pull", чтобы загрузить все файлы, отслеживаемые LFS.
+1. Выполните команду "git submodule update --init --recursive", чтобы обновить и инициализировать все подмодули в репозитории.
+1. Выполните команду "mb2 -t AuroraOS-5.0.0.60-base-armv7hl build-init", чтобы инициализировать окружение сборки.
+1. Выполните команду "mb2 -t AuroraOS-5.0.0.60-base-armv7hl prepare", чтобы применить патчи, необходимые для сборки.
+1. Выполните команду "mb2 -t AuroraOS-5.0.0.60-base-armv7hl build", чтобы начать сборку пакета.
+1. Выполните команду для подписи rpm-пакета:
+```
+sfdk engine exec rpmsign-external sign  \
+    --key absolute/path/to/key/file.pem \
+    --cert absolute/path/to/cert/file.pem \
+      absolute/path/to/rpm/package.rpm
+```
+Целевой rpm-пакет находится в каталоге RPMS.
+
+### Решение возможных проблем
+
+Если сборка проекта упала со следующей ошибкой
+```
+ aclocal -I <path/to>/DocumentConverter/upstream/m4
+autom4te: error: need GNU m4 1.4 or later: /usr/bin/m4
+aclocal: error: echo failed with exit status: 1
+```
+
+то требуется зайти в таргет и установить вручную зависимость m4.
+
+### Повторная сборка под другой таргет
+
+Поскольку сборка проходит в той же самой директории, что и основной исходный код, перед сборкой под новый таргет требуется удалить результат предыдущий сборки.
+Для этого требуется выполнить следующие команды из корня проекта:
+1. `rm -fr libs_build`
+2. `rm -fr upstream/workdir`
+3. `rm -f application/Makefile`
+4. `cd libs/liblangtag && make distclean`
