 ## Usage
 
-gifski is a command-line tool. There is no GUI for Windows or Linux (there is one for [macOS](https://sindresorhus.com/gifski)).
+gifski is a command-line tool. If you're not comfortable with a terminal, try the GUI version for [Windows][winmsi] or for [macOS][macapp].
 
-The recommended way is to first export video as PNG frames. If you have `ffmpeg` installed, you can run in terminal:

+
+### From ffmpeg video
+
+> Tip: Instead of typing file paths, you can drag'n'drop files into the terminal window!
+
+If you have ffmpeg installed, you can use it to stream a video directly to the gifski command by adding `-f yuv4mpegpipe` to `ffmpeg`'s arguments:
+
+```sh
+ffmpeg -i video.mp4 -f yuv4mpegpipe | gifski -o anim.gif -
+```
+
+Replace "video.mp4" in the above code with actual path to your video.
+
+Note that there's `-` at the end of the command. This tells `gifski` to read from standard input. Reading a `.y4m` file from disk would work too, but these files are huge.
+
+`gifski` may automatically downsize the video if it has resolution too high for a GIF. Use `--width=1280` if you can tolerate getting huge file sizes.
+
+### From PNG frames
+
+A directory full of PNG frames can be used as an input too. You can export them from any animation software. If you have `ffmpeg` installed, you can also export frames with it:
 
 ```sh
 ffmpeg -i video.webm frame%04d.png

-You can also resize frames (with `-W <width in pixels>` option). If the input was ever encoded using a lossy video codec it's recommended to at least halve size of the frames to hide compression artefacts and counter chroma subsampling that was done by the video codec.
+Note that `*` is a special wildcard character, and it won't work when placed inside quoted string (`"*"`).

-The tool optionally supports decoding video directly, but unfortunately it relies on ffmpeg 4.x, which may be *very hard* to get working, so it's not enabled by default.
+The tool optionally supports decoding video directly, but unfortunately it relies on ffmpeg 6.x, which may be *very hard* to get working, so it's not enabled by default.
 
 You must have `ffmpeg` and `libclang` installed, both with their C headers installed in default system include paths. Details depend on the platform and version, but you usually need to install packages such as `libavformat-dev`, `libavfilter-dev`, `libavdevice-dev`, `libclang-dev`, `clang`. Please note that installation of these dependencies may be quite difficult. Especially on macOS and Windows it takes *expert knowledge* to just get them installed without wasting several hours on endless stupid installation and compilation errors, which I can't help with. If you're cross-compiling, try uncommenting `[patch.crates-io]` section at the end of `Cargo.toml`, which includes some experimental fixes for ffmpeg.
