 It's safe and efficient to call `gifski_add_frame_*` in a loop as fast as you can get frames,
 because it blocks and waits until previous frames are written.
+
+To cancel processing, make progress callback return 0 and call `gifski_finish()`. The write callback
+may still be called between the cancellation and `gifski_finish()` returning.
+
+To build as a library:
+
+```bash
+cargo build --release --lib
+```
+
+it will create `target/release/libgifski.a` (static library)
+and `target/release/libgifski.so`/`dylib` or `gifski.dll` (dynamic library)
+
+Static is recommended.
+
+To build for iOS:
+
+```bash
+rustup target add aarch64-apple-ios
+cargo build --release --lib --target aarch64-apple-ios
+```
+
+it will build `target/aarch64-apple-ios/release/libgifski.a` (ignore the warning about cdylib).
