 # vips-ffm
 
-A thin wrapper to let Java/JVM projects use [libvips](https://github.com/libvips/libvips), via the
-"Foreign Function & Memory API" ([JEP 454](https://openjdk.org/jeps/454)) released in JDK 22.
+[libvips](https://github.com/libvips/libvips) bindings for JVM projects, using the "Foreign Function & Memory API"
+([JEP 454](https://openjdk.org/jeps/454)) released in JDK 22. The combination of libvips and FFM makes for performant, safe, and ergonomic image
+manipulation in JVM systems, supporting a vast range of image formats, including HEIC, JXL, WebP, PNG, JPEG, and more.
+Pronounced "vips (like zips) eff-eff-emm".
 
-Incubating in [Photo Fox](https://github.com/lopcode/photo-fox). Pronounced "vips (like hips) eff-eff-emm".
+Bindings are automatically generated using `jextract`, and enhanced with some helpful wrapper functions to make usage
+more idiomatic.

 ## Project goals
 
 * Publish to GitHub Packages via Gradle, so that using the library is as easy as
-`implementation("app.photofox:vips-ffm-core:$version")`
-* Automate as much as possible, including API generation via `jextract`, so upstream changes can be rapidly integrated
-* Core module should only include this automated output, with a minimum of extra things that can break as ImageMagick
-changes
+`implementation("app.photofox:vips-ffm-core:$version")` (TODO)
+* Automate as much as possible, including API generation via [jextract](https://github.com/openjdk/jextract), so
+  upstream changes can be rapidly integrated ✅
+* Core module should only include this automated output, with a minimum of extra things that can break as upstreams
+  change ✅
 * If helpers are required, publish in another artifact
 * Incubate in Photo Fox with some "real world" usage
 
-## Proof of concept
+## Samples
+
+Samples are included that show various usages of the `libvips` bindings. They include validations, and run on GitHub
+Actions to validate new versions during development.
 
-This project includes a proof of concept that only runs on macOS. To run it:
+To get set up to run samples (on macOS):
 * `brew install vips`
 * `sdk use java 22-open`
 * `./setup_lib_symlinks.sh`
 * (Optional, to regenerate bindings) `./generate_ffm_bindings.sh`
-* Run `VipsFfm` in IntelliJ to run samples and validations
-
-### Example output
+* Then either:
+  * Run `./run_samples.sh` in your terminal
+  * Run `VipsFfm` in IntelliJ to run samples and validations
