This means that ReactOS is under heavy development, things may not work well and it can corrupt the data present on your hard disk. It is recommended to test ReactOS on a virtual machine or on a computer with no sensitive or critical data!*** 48 49## Building 50 51 [![rosbewin.badge]][rosbewin.link] [![rosbeunix.badge]][rosbeunix.link] [![coverity.badge]][coverity.link] 52 53To build the system it is strongly advised to use the _ReactOS Build Environment (RosBE)._ 54Up-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). 55 56Alternatively 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). 57 58See ["Building ReactOS"](https://reactos.org/wiki/Building_ReactOS) article for more details. 59 60### Binaries 61 62To 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. 63 64### Bootable images 65 66To build a bootable CD image run `ninja bootcd` from the build directory. This will create a CD image with a filename `bootcd.iso`. 67 68You can always download fresh binary builds of bootable images from the ["Daily builds"](https://reactos.org/getbuilds/) page. 69 70## Installing 71 72By default, ReactOS currently can only be installed on a machine that has a FAT16 or FAT32 partition as the active (bootable) partition. 73The 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. 74ReactOS Setup can format the partitions if needed. 75 76Starting 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. 77 78To install ReactOS from the bootable CD distribution, extract the archive contents. Then burn the CD image, boot from it, and follow the instructions. 79 80See ["Installing ReactOS"](https://reactos.org/wiki/Installing_ReactOS) Wiki page or [INSTALL](INSTALL) for more details. 81 82## Testing 83 84If 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. 85 86See ["File Bugs"](https://reactos.org/wiki/File_Bugs) for a guide. 87 88__NOTE:__ The bug tracker is _not_ for discussions. Please use our [official chat](https://chat.reactos.org/) or our [forum](https://reactos.org/forum/). 89 90## Contributing [![prwelcome.badge]](https://reactos.org/wiki/Commiting_Changes) 91 92We are always looking for developers! Check [how to contribute](CONTRIBUTING.md) if you are willing to participate. 93 94__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. 95 96Try out cloud-based ReactOS development using Gitpod and Docker: 97 98[](https://gitpod.io/#https://github.com/reactos/reactos) 99 100You 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). 101 102## More information 103 104ReactOS is a Free and Open Source operating system based on the Windows architecture, 105providing support for existing applications and drivers, and an alternative to the current dominant consumer operating system. 106 107It 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. 108 109ReactOS 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. 110 111More information is available at: [reactos.org](https://reactos.org/). 112 113Also see the [media/doc](/media/doc/) subdirectory for some sparse notes. 114 115## Who is responsible 116 117Active devs are listed as members of [GitHub organization](https://github.com/orgs/reactos/people). 118See also the [CREDITS](CREDITS) file for others. 119 120## Code mirrors 121 122The 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. 123 124There is also an obsolete [SVN archive repository](https://svn.reactos.org/reactos/) that is kept for historical purposes. 125 126[coverity.badge]: https://scan.coverity.com/projects/205/badge.svg?flat=1 127[rosbewin.badge]: https://img.shields.io/badge/RosBE_Windows-2.2.0-0688CB.svg 128[rosbeunix.badge]: https://img.shields.io/badge/RosBE_Unix-2.2-0688CB.svg 129[prwelcome.badge]: https://img.shields.io/badge/PR-welcome-0688CB.svg 130 131[coverity.link]: https://scan.coverity.com/projects/205 132[rosbewin.link]: https://sourceforge.net/projects/reactos/files/RosBE-Windows/i386/2.2.0/ 133[rosbeunix.link]: https://sourceforge.net/projects/reactos/files/RosBE-Unix/2.2/ 134
