 ## Compiling and installing libimg manually
 
-Building libimg for the calculator requires a SuperH compiler. If you have `sh-elf-gcc`, then you're ready to go. libimg will be compiled for both fx-9860G (Graph 35+E-like) and fx-CG 50 (Graph 90+E), and it will install itself in the proper compiler-managed directory.
+libimg should be built with the [fxSDK](/Lephenixnoir/fxsdk), which provides the tools and settings needed to compile for the calculator.
 
 ```
-% make
-% make install
+% fxsdk build-fx install
+% fxsdk build-cg install
 ```
 
-If you have an older setup with `sh3eb-elf` and/or `sh4eb-elf`, edit the configuration file `libimg.conf` before building, as follows:
-
-* Set either the `target-fx` or `target-cg` line to use the proper compiler.
-* If you need to completely disable one of the platforms, comment out the line that sets `lib-fx` or `lib-cg`.
-
 Additionally, this repository has a simple testing system for Linux in the `testing` folder.
 
 * Use `make` from that folder to compile `main.c` into a `libimg` executable that reads RGB565 bitmap files into `img_t` images and performs a few transforms.
