Different things may not work well and it can corrupt the data present on your hard disk. It is HIGHLY recommended to test ReactOS on a virtual machine or on a computer with no sensitive or critical data! 51 52## Building 53 54 [![rosbewin.badge]][rosbewin.link] [![rosbeunix.badge]][rosbeunix.link] [![coverity.badge]][coverity.link] 55 56To build the system it is strongly advised to use the _ReactOS Build Environment (RosBE)._ 57Up-to-date versions for Windows and for Unix/GNU-Linux are available from our download page at: ["Build Environment"](https://reactos.org/wiki/Build_Environment). 58 59Alternatively one can use Microsoft Visual C++ (MSVC) version 2015+. Building with MSVC is covered here: ["Visual Studio or Microsoft Visual C++"](https://reactos.org/wiki/CMake#Visual_Studio_or_Microsoft_Visual_C.2B.2B). 60 61See ["Building ReactOS"](https://reactos.org/wiki/Building_ReactOS) article for more details. 62 63### Binaries 64 65To build ReactOS you must run the `configure` script in the directory you want to have your build files. Choose `configure.cmd` or `configure.sh` depending on your system. Then run `ninja <modulename>` to build a module you want or just `ninja` to build all modules. 66 67### Bootable images 68 69To build a bootable CD image run `ninja bootcd` from the build directory. This will create a CD image with a filename `bootcd.iso`. 70 71You can always download fresh binary builds of bootable images from the ["Daily builds"](https://reactos.org/getbuilds/) page. 72 73## Installing 74 75By default, ReactOS currently can only be installed on a machine that has a FAT16 or FAT32 partition as the active (bootable) partition. 76The partition on which ReactOS is to be installed (which may or may not be the bootable partition) must also be formatted as FAT16 or FAT32. 77ReactOS Setup can format the partitions if needed. 78 79Starting with 0.4.10, ReactOS can be installed using the BtrFS file system. But consider this as an experimental feature and thus regressions not triggered on FAT setup may be observed. 80 81To install ReactOS from the bootable CD distribution, extract the archive contents. Then burn the CD image, boot from it, and follow the instructions. 82 83See ["Installing ReactOS"](https://reactos.org/wiki/Installing_ReactOS) Wiki page or [INSTALL](INSTALL) for more details. 84 85## Testing 86 87If you discover a bug in ReactOS search on JIRA first - it might be reported already. If not report the bug providing logs and as much information as possible. 88 89See ["File Bugs"](https://reactos.org/wiki/File_Bugs) for a guide. 90 91__NOTE:__ The bug tracker is _not_ for discussions. Please use our [official chat](https://chat.reactos.org/) or our [forum](https://reactos.org/forum/). 92 93## Contributing [![prwelcome.badge]](https://reactos.org/wiki/Commiting_Changes) 94 95We are always looking for developers! Check [how to contribute](CONTRIBUTING.md) if you are willing to participate. 96 97__Legal notice__: If you have seen proprietary Microsoft Windows source code (including but not limited to the leaked Windows NT 3.5, NT 4, 2000 source code and the Windows Research Kernel), your contribution won't be accepted because of potential copyright violation. 98 99Try out cloud-based ReactOS development using Gitpod and Docker: 100 101[](https://gitpod.io/#https://github.com/reactos/reactos) 102 103You can also support ReactOS by [donating](https://reactos.org/donate/)! We rely on our backers to maintain our servers and accelerate development by [hiring full-time devs](https://reactos.org/contributing/#paid-jobs). 104 105## More information 106 107ReactOS is a Free and Open Source operating system based on the Windows architecture, 108providing support for existing applications and drivers, and an alternative to the current dominant consumer operating system. 109 110It is not another wrapper built on Linux, like WINE. It does not attempt or plan to compete with WINE; in fact, the user-mode part of ReactOS is almost entirely WINE-based and our two teams have cooperated closely in the past. 111 112ReactOS is also not "yet another OS". It does not attempt to be a third player like any other alternative OS out there. People are not meant to uninstall Linux and use ReactOS instead; ReactOS is a replacement for Windows users who want a Windows replacement that behaves just like Windows. 113 114More information is available at: [reactos.org](https://reactos.org/). 115 116Also see the [media/doc](/media/doc/) subdirectory for some sparse notes. 117 118## Who is responsible 119 120Active devs are listed as members of [GitHub organization](https://github.com/orgs/reactos/people). 121See also the [CREDITS](CREDITS) file for others. 122 123## Code mirrors 124 125The main development is done on [GitHub](https://github.com/reactos/reactos). We have an [alternative mirror](https://git.reactos.org/?p=reactos.git) in case GitHub is down. 126 127There is also an obsolete [SVN archive repository](https://svn.reactos.org/reactos/) that is kept for historical purposes. 128 129[coverity.badge]: https://scan.coverity.com/projects/205/badge.svg?flat=1 130[rosbewin.badge]: https://img.shields.io/badge/RosBE_Windows-2.2.0-0688CB.svg 131[rosbeunix.badge]: https://img.shields.io/badge/RosBE_Unix-2.2-0688CB.svg 132[prwelcome.badge]: https://img.shields.io/badge/PR-welcome-0688CB.svg 133 134[coverity.link]: https://scan.coverity.com/projects/205 135[rosbewin.link]: https://sourceforge.net/projects/reactos/files/RosBE-Windows/i386/2.2.0/ 136[rosbeunix.link]: https://sourceforge.net/projects/reactos/files/RosBE-Unix/2.2/ 137
