+##Build instructions for Qt Creator 2.7 under Ubuntu 14.04
+
+###Prepare
+
+* Install git by command **sudo apt-get install git** in Terminal
+* Install g++ by command **sudo apt-get install g++** in Terminal
+* Install Qt Creator from Ubuntu Software Center
+
+###Prepare folder
+
+Choose a folder for the future build, for example **/home/user/TBuild** There you will have two folders, **Libraries** for third-party libs and **tdesktop** (or **tdesktop-master**) for the app.
+
+###Clone source code
+
+By git – in Terminal go to **/home/user/TBuild** and run
+
+     git clone https://github.com/telegramdesktop/tdesktop.git
+
+or download in ZIP and extract to **/home/user/TBuild** rename **tdesktop-master** to **tdesktop** to have **/home/user/TBuild/tdesktop/Telegram/Telegram.pro** project
+
+###Prepare libraries
+
+####OpenSSL 1.0.1g
+
+http://www.openssl.org/source/ > Download [**openssl-1.0.1h.tar.gz**](http://www.openssl.org/source/openssl-1.0.1h.tar.gz) (4.3 Mb)
+
+Extract openssl-1.0.1h.tar.gz to **/home/user/TBuild/Libraries**
+
+#####Building library
+
+In Terminal go to **/home/user/TBuild/Libraries/openssl-1.0.1h** and there run
+
+    ./config
+    make
+    sudo make install
+
+####liblzma
+
+http://tukaani.org/xz/ > Download [**xz-5.0.5.tar.gz**](http://tukaani.org/xz/xz-5.0.5.tar.gz)
+
+Extract to **/home/user/TBuild/Libraries**
+
+#####Building library
+
+In Terminal go to **/home/user/TBuild/Libraries/xz-5.0.5** and there run
+
+    ./configure
+    make
+    sudo make install
+
+####zlib 1.2.8
+
+http://zlib.net/ > Download [**zlib source code, version 1.2.8, tar.gz format**](http://zlib.net/zlib-1.2.8.tar.gz)
+
+Extract to **/home/user/TBuild/Libraries**
+
+#####Building library
+
+In Terminal go to **/home/user/TBuild/Libraries/zlib-1.2.8** and there run
+
+    ./configure
+    make
+    sudo make install
+
+####libexif 0.6.20
+
+Get sources from https://github.com/telegramdesktop/libexif-0.6.20, by git – in Terminal go to **/home/user/TBuild/Libraries** and run
+
+    git clone https://github.com/telegramdesktop/libexif-0.6.20.git
+
+or download in ZIP and extract to **/home/user/TBuild/Libraries**, rename **libexif-0.6.20-master** to **libexif-0.6.20** to have **/home/user/TBuild/Libraries/libexif-0.6.20/configure** script
+
+#####Building library
+
+In Terminal go to **/home/user/TBuild/Libraries/libexif-0.6.20** and there run
+
+    ./configure
+    make
+    sudo make install
+
+####Qt 5.3.1, slightly patched
+
+http://download.qt-project.org/official_releases/qt/5.3/5.3.1/single/qt-everywhere-opensource-src-5.3.1.tar.gz
+
+Extract to **/home/user/TBuild/Libraries**, rename **qt-everywhere-opensource-src-5.3.1** to **QtStatic** to have **/home/user/TBuild/Libraries/QtStatic/qtbase** folder
+
+Apply patch – copy (with overwrite!) everything from **/home/user/TBuild/tdesktop/\_qt\_5\_3\_1\_patch/** to **/home/user/TBuild/Libraries/QtStatic/**
+
+#####Building library
+
+Install some packages for Qt (see **/home/user/TBuild/Libraries/QtStatic/qtbase/src/plugins/platforms/xcb/README**)
+
+    sudo apt-get install libxcb-image0-dev
+    sudo apt-get install libxcb-keysyms1-dev
+    sudo apt-get install libxcb-icccm4-dev
+    sudo apt-get install libxcb-render-util0-dev
+    sudo apt-get install libxrender-dev
+    sudo apt-get install libpulse-dev
+
+In Terminal go to **/home/user/TBuild/Libraries/QtStatic** and there run
+
+    ./configure -release -opensource -no-opengl -static -nomake examples -skip qtquick1 -skip qtdeclarative
+    y
+    make
+    sudo make install
+
+building (**make** command) will take really long time.
+
+In Ubuntu under Parallels Desktop there was a problem with libGL, bad symlink **/usr/lib/x86_64-linux-gnu/mesa/libGL.so** to unexisting file, had to fix it manually like this
+
+    sudo ln -sf libGL.so.1 /usr/lib/x86_64-linux-gnu/mesa/libGL.so
+
+because only **/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1** existed.
+
+#####Building pulseaudio plugin
+
+In Terminal go to **/home/user/TBuild/Libraries/QtStatic/qtmultimedia/src/plugins/pulseaudio** and run
+
+    qmake pulseaudio.pro
+    make
+
+###Building Telegram Desktop
+
+* Launch Qt Creator, all projects will be taken from **/home/user/TBuild/tdesktop/Telegram**
+* Tools > Options > Build & Run > Qt Versions tab > Add > File System /usr/local/Qt-5.3.1/bin/qmake > **Qt 5.3.1 (Qt-5.3.1)** > Apply
+* Tools > Options > Build & Run > Kits tab > Desktop (default) > change **Qt version** to **Qt 5.3.1 (Qt-5.3.1)** > Apply
+* Open MetaStyle.pro, configure project with paths **/home/user/TBuild/tdesktop/Linux/DebugIntermediateStyle** and **/home/user/TBuild/tdesktop/Linux/ReleaseIntermediateStyle** and build for Debug
+* Open MetaEmoji.pro, configure project with paths **/home/user/TBuild/tdesktop/Linux/DebugIntermediateEmoji** and **/home/user/TBuild/tdesktop/Linux/ReleaseIntermediateEmoji** and build for Debug
+* Open MetaLang.pro, configure project with paths **/home/user/TBuild/tdesktop/Linux/DebugIntermediateLang** and **/home/user/TBuild/tdesktop/Linux/ReleaseIntermediateLang** and build for Debug
+* Open Telegram.pro, configure project with paths **/home/user/TBuild/tdesktop/Linux/DebugIntermediate** and **/home/user/TBuild/tdesktop/Linux/ReleaseIntermediate** and build for Debug
+* Open Updater.pro, configure project with paths **/home/user/TBuild/tdesktop/Linux/DebugIntermediateUpdater** and **/home/user/TBuild/tdesktop/Linux/ReleaseIntermediateUpdater** and build for Debug
+* Release Telegram build will require removing **CUSTOM_API_ID** definition in Telegram.pro project and may require changing paths in **/home/user/TBuild/tdesktop/Telegram/FixMake.sh** for static library linking fix
