 # Vim AppImage Repository
 
-This is a project for building a 64bit Gvim AppImage from the latest Vim snapshots.
-AppImage is a form of cross-distribution packaging format that can be run
-everywhere by simply downloading the image and starting it. For more
-information about the package format see here: [AppImage](https://appimage.org).
+**Note**: this is a *fork* of the [official vim/vim-appimage](https://github.com/vim/vim-appimage/) repo. It uses a newer Ubuntu base image (22.04 "jammy" — avoiding some warnings when running GVim on current Linux distros) and compiles Vim with dynamic Python 3 interfaces (currently unavailable in the original repo).
 
-The image is based on Ubuntu LTS ~~18.04 bionic~~ 20.04 "focal" (since PR #47,
-because Github retired the Ubuntu 18.04 images in April 2023).
+This project builds 64bit Vim & Gvim AppImage releases from the latest Vim snapshots.  AppImage is a form of cross-distribution packaging format that runs from a single file on "any" system (in practice, "too different" distros might not be compatible). https://appimage.org/ has more information about the format.
 
-[Download](https://github.com/vim/vim-appimage/releases) and execute the most
-recent GVim AppImage file to run GVim. It most likely won't work on older
-distributions — you could try the [last Ubuntu 18.04-based release
-(v9.0.1413)](https://github.com/vim/vim-appimage/releases/tag/v9.0.1413).
+[Download](releases) and execute the most recent GVim AppImage to run GVim (previous releases in this repo go back to Vim `v9.1.0228`). On older distributions, it most likely won't work — you could try the [last Ubuntu 18.04-based release (v9.0.1413)](https://github.com/vim/vim-appimage/releases/tag/v9.0.1413) from the [vim/vim-appimage](https://github.com/vim/vim-appimage/) repo.
 
-For terminal Vim, create a symbolic link with a name starting with "vim" to the
-GVim AppImage, as explained in the release notes; or download a Vim AppImage
-(with no X11 features) instead from the most recent release.
+See the release notes for running
+* terminal Vim from the GVim appimage
+* the separate Vim AppImage built with no X11 dependencies (but no X11 support)
+* locally-extracted AppImages
 
-The vim / gvim included in the AppImage was built with Perl, Python2, Ruby and
-Lua support. See the release notes for details.
