 # angelscript_vita
 A work-in-progress re-port of AngelScript 2.32.0 from the old "SN Systems ProDG" (Official Dev Kit) to the GCC-based unofficial VITASDK
+
+## Building
+Ensure you have VITASDK installed and configured correctly. You also need VITASDK in your path.
+This version of AngelScript for PS Vita compiles as a static library. 
+
+**PLEASE** use the CMake project files for ease of configuration and building.
+
+1. Clone repo
+2. cd into repo (`cd angelscript_vita`)
+3. cd into library CMake Project folder (`cd sdk/angelscript/project/cmake`)
+4. mkdir for build files (`mkdir build_vita && cd build_vita`)
+5. CMake Configuration: `cmake -DCMAKE_TOOLCHAIN_FILE=$VITASDK/share/vita.toolchain.cmake [-DCMAKE_BUILD_TYPE=Debug|Release] ../`
+6. Build: `make -j4 && make install`
+7. ???
+8. Test out some projects! Statically link `libangelscript.a`. The `game` sample is the only one that's been modified to build Vita VPK (does NOT display anything, just a small test for loading AngelScript files & testing multiple files, references, etc.), try that one out if you have debugnet installed & know how to use it. 
+
+## Misc. Information
+
+Ported to the unofficial PS Vita SDK by Axiom.
+Axiom does NOT own AngelScript.
+
+Modifications are documented when & where they can be!
