+# Conquest Save File Patcher
+
+BSP scrips that work on Pokemon Conquest save data
+
+## Download the patch script
+
+(todo: add releases page)
+
+## Building the project yourself
+
+On Linux, Mac, or WSL:
+
+    git clone --recurse-submodules https://github.com/MathyFurret/conquestsavefiletools
+    cd conquestsavefiletools
+    make
+
+This builds conquestsavefiletools.bsp. GCC is used to build the BSP compiler; to use a different C compiler, simply run a command that builds `bsp/bspcomp` yourself.
+
+## Patching your save
+
+Go to https://aaaaaa123456789.github.io/bsp/. Drop the .bsp under "Patch file" and your save file under "Input file", then click "Begin patching" and select the patch you want.
