+## Documentation
+- [PlusLib API documentation](http://perk-software.cs.queensu.ca/plus/doc/nightly/dev/): generated nightly from the latest code version.
+- [Plus devices](https://plustoolkit.github.io/devicecode): description of the steps requires to implement a new device interface.
+- Notepad++ log file syntax highlighting is available via [this user-defined language](https://plustoolkit.github.io/files/PlusLog_NotepadPP_Language.xml).
+
+## Testing dashboards
+
+- [PlusLib dashboard](http://perkdata.cs.queensu.ca/CDash/index.php?project=PlusLib): results of automatic tests of the Plus library
+- [PlusApp dashboard](http://perkdata.cs.queensu.ca/CDash/index.php?project=PlusApp): results of automatic tests of the Plus applications
+
+
+## Build instructions
+
+Plus library files and all required libraries and toolkits are automatically downloaded, configured, and built using CMake "superbuild" method (using CMake external project infrastructure). Build instructions are available in [PlusBuild repository](https://github.com/PlusToolkit/PlusBuild/blob/master/README.md).
+
+Supported platforms:
+- 32/64-bit builds: Plus can be built in either 32-bit or 64-bit mode. 64-bit applications have the advantage of larger available memory space (which is useful for certain applications, such as recording a large number of frames in memory, or reconstructing high-resolution volumes), but only a few hardware devices have 64-bit compatible drivers. If available memory is not a concern  then use only 32-bit builds. If lots of memory is needed, and the application does not have to use tracking or imaging hardware devices directly then 64-bit build of Plus can be used. If both hardware support and lots of memory is needed then a 32-bit build of Plus can be used for data acquisition and the acquired data can be passed on to a 64-bit Plus or other application for further processing.
+- Windows 7 32-bit/64-bit, Windows 10 32-bit/64-bit, Windows XP 32-bit embedded, Ubuntu 16.04, and MacOSX operating systems are fully supported and regularly tested.
+- Running on Linux and MacOS: Unfortunately, many of the drivers written for devices are Windows specific, and thus capture cannot be done on a Linux or MacOSX machine. It is recommended to do the data acquisition on Windows and stream the acquired data to the Linux or MacOS computer for further processing.
