If you have a question or want to discuss the best way to do something with Vim, you can use [StackExchange](https://vi.stackexchange.com/) or one of the [Maillists](https://www.vim.org/community.php). ## What is Vim? ## Vim is a greatly improved version of the good old UNIX editor [Vi](https://en.wikipedia.org/wiki/Vi). Many new features have been added: multi-level undo, syntax highlighting, command line history, on-line help, spell checking, filename completion, block operations, script language, etc. There is also a Graphical User Interface (GUI) available. Still, Vi compatibility is maintained, those who have Vi "in the fingers" will feel at home. See [`runtime/doc/vi_diff.txt`](runtime/doc/vi_diff.txt) for differences with Vi. This editor is very useful for editing programs and other plain text files. All commands are given with normal keyboard characters, so those who can type with ten fingers can work very fast. Additionally, function keys can be mapped to commands by the user, and the mouse can be used. Vim runs under MS-Windows (XP, Vista, 7, 8, 10), macOS, Haiku, VMS and almost all flavours of UNIX. Porting to other systems should not be very difficult. Older versions of Vim run on MS-DOS, MS-Windows 95/98/Me/NT/2000, Amiga DOS, Atari MiNT, BeOS, RISC OS and OS/2. These are no longer maintained. For Vim9 script see [README_VIM9](README_VIM9.md). ## Distribution ## You can often use your favorite package manager to install Vim. On Mac and Linux a small version of Vim is pre-installed, you still need to install Vim if you want more features. There are separate distributions for Unix, PC, Amiga and some other systems. This `README.md` file comes with the runtime archive. It includes the documentation, syntax files and other files that are used at runtime. To run Vim you must get either one of the binary archives or a source archive. Which one you need depends on the system you want to run it on and whether you want or must compile it yourself. Check http://www.vim.org/download.php for an overview of currently available distributions. Some popular places to get the latest Vim: * Check out the git repository from [GitHub](https://github.com/vim/vim). * Get the source code as an [archive](https://github.com/vim/vim/releases). * Get a Windows executable from the [vim-win32-installer](https://github.com/vim/vim-win32-installer/releases) repository. ## Compiling ## If you obtained a binary distribution you don't need to compile Vim. If you obtained a source distribution, all the stuff for compiling Vim is in the [`src`](/src) directory. See [`src/INSTALL`](src/INSTALL) for instructions. ## Installation ## See one of these files for system-specific instructions. Either in the [READMEdir directory](./READMEdir/) (in the repository) or the top directory (if you unpack an archive): README_ami.txt Amiga README_unix.txt Unix README_dos.txt MS-DOS and MS-Windows README_mac.txt Macintosh README_haiku.txt Haiku README_vms.txt VMS There are other `README_*.txt` files, depending on the distribution you used. ## Documentation ## The Vim tutor is a one hour training course for beginners. Often it can be started as `vimtutor`. See `:help tutor` for more information. The best is to use `:help` in Vim. If you don't have an executable yet, read [`runtime/doc/help.txt`](/runtime/doc/help.txt). It contains pointers to the other documentation files. The User Manual reads like a book and is recommended to learn to use Vim. See `:help user-manual`. ## Copying ## Vim is Charityware. You can use and copy it as much as you like, but you are encouraged to make a donation to help orphans in Uganda. Please read the file [`runtime/doc/uganda.txt`](runtime/doc/uganda.txt) for details (do `:help uganda` inside Vim). Summary of the license: There are no restrictions on using or distributing an unmodified copy of Vim. Parts of Vim may also be distributed, but the license text must always be included. For modified versions a few restrictions apply. The license is GPL compatible, you may compile Vim with GPL libraries and distribute it. ## Sponsoring ## Fixing bugs and adding new features takes a lot of time and effort. To show your appreciation for the work and motivate Bram and others to continue working on Vim please send a donation. Since Bram is back to a paid job the money will now be used to help children in Uganda. See [`runtime/doc/uganda.txt`](runtime/doc/uganda.txt). But at the same time donations increase Bram's motivation to keep working on Vim!
