 ### Compile
 
-Install ImageMagick7, MuPDF and libheif (with libaom) libraries and headers and then install to GOBIN:
+You must have `CGO_ENABLED=1`. Note that `Go` will disable cgo when cross-compiling.
 
-`go install -tags extlib github.com/gen2brain/cbconvert/cmd/cbconvert@latest`
+Install to `GOBIN` (you can point `GOBIN` to e.g. `/usr/local/bin` or `~/.local/bin`):
+
+`go install github.com/gen2brain/cbconvert/cmd/cbconvert@latest`
+
+For GUI app, check [IUP](https://github.com/gen2brain/iup-go) requirements, and then install:
+
+`go install github.com/gen2brain/cbconvert/cmd/cbconvert-gui@latest`
+
+### Build tags
+
+* `extlib` - use external `libmupdf` and `libunarr` libraries
+* `pkgconfig` - enable pkg-config (used with `extlib`)
