3 CMSIS Version 5.0.1 release is now available. The [pre-built documentation](http://arm-software.github.io/CMSIS_5/General/html/index.html) is available under http://arm-software.github.io/CMSIS_5/General/html/index.html
5 Note that this repository gives our users and partners contiguous access to the CMSIS development. It allows you to review the work and provide feedback or create pull requests for contributions.
7 This GitHub repository development branch reflects our current state of development and is constantly updated.
8 A [pre-built documentation](http://www.keil.com/pack/doc/CMSIS_Dev/index.html) is updated from time to time, but may be generated also using the instructions published under [Generate CMSIS Pack for Release](https://github.com/ARM-software/CMSIS_5#generate-cmsis-pack-for-release).

50 ## Generate CMSIS Pack for Release
52 This GitHub development repository contains already pre-build libraries of various libraries (DSP, RTOS, RTOS2).
53 These libraries are validated for release.
55 To build a complete CMSIS pack for installation the following additional tools are required:
56 - **doxygen.exe** Version: 1.8.6 (Documentation Generator)
57 - **mscgen.exe** Version: 0.20 (Message Sequence Chart Converter)
58 - **7z.exe (7-Zip)** Version: 16.02 (File Archiver)
60 Using these tools, you can generate on a Windows PC:
61 - **CMSIS Software Pack** using the batch file **gen_pack.bat** (located in ./CMSIS/Utilities). This batch file also generates the documentation.
63 - **CMSIS Documentation** using the batch file **genDoc.bat** (located in ./CMSIS/Doxygen).
65 The file ./CMSIS/DoxyGen/How2Doc.txt describes the rules for creating API documentation.
