+@@ -53,12 +53,18 @@ On Windows, SameBoy also requires:
+ To compile, simply run `make`. The targets are:
+  * `cocoa` (Default for macOS)
+  * `sdl` (Default for everything else)
+- * `lib` (Creates libsameboy.o and libsameboy.a for statically linking SameBoy, as well as a headers directory with corresponding headers; currently not supported on Windows due to linker limitations)
++ * `lib` (Creates libsameboy.o, libsameboy.a and libsameboy.so for linking SameBoy, as well as a headers directory with corresponding headers; currently not supported on Windows due to linker limitations)
+  * `ios` (Plain iOS .app bundle), `ios-ipa` (iOS IPA archive for side-loading), `ios-deb` (iOS deb package for jailbroken devices)
+  * `libretro`
+  * `bootroms`
+  * `tester` 
+ 
++For convenience, when installing the static and shared libraries is
++desired, you can specify the LIBRARY=1 make variable to have the
++libraries built as part of the default target, as well as installed,
++along the headers. Alternatively, `LIBRARY=shared` will install just
++the shared library, while `LIBRARY=static` only the static one.
++
+ You may also specify `CONF=debug` (default), `CONF=release`, `CONF=native_release` or `CONF=fat_release`  to control optimization, symbols and multi-architectures. `native_release` is faster than `release`, but is optimized to the host's CPU and therefore is not portable. `fat_release` is exclusive to macOS and builds x86-64 and ARM64 fat binaries; this requires using a recent enough `clang` and macOS SDK using `xcode-select`, or setting them explicitly with `CC=` and `SYSROOT=`, respectively. All other configurations will build to your host architecture, except for the iOS targets. You may set `BOOTROMS_DIR=...` to a directory containing precompiled boot ROM files, otherwise the build system will compile and use SameBoy's own boot ROMs.
+ 
+ The SDL port will look for resource files with a path relative to executable and inside the directory specified by the `DATA_DIR` variable. If you are packaging SameBoy, you may wish to override this by setting the `DATA_DIR` variable during compilation to the target path of the directory containing all files (apart from the executable, that's not necessary) from the `build/bin/SDL` directory in the source tree. Make sure the variable ends with a `/` character. On FreeDesktop environments, `DATA_DIR` will default to `/usr/local/share/sameboy/`. `PREFIX` and `DESTDIR` follow their standard usage and default to an empty string an `/usr/local`, respectively
