 Install the **devkitARM** toolchain of [devkitPro](https://devkitpro.org/wiki/Getting_Started) and add its environment variables. For Windows versions without the Linux subsystem, the devkitPro [graphical installer](https://github.com/devkitPro/installer/releases) includes a preconfigured MSYS2 environment, thus the steps below are not required.

 ## Installation
 
 To set up the repository:
 
-	git clone https://github.com/pret/pokefirered
-	git clone https://github.com/pret/agbcc
+    git clone https://github.com/pret/pokefirered
+    git clone https://github.com/pret/agbcc
 
-	cd ./agbcc
-	sh build.sh
-	sh install.sh ../pokefirered
+    cd ./agbcc
+    sh build.sh
+    sh install.sh ../pokefirered
 
-	cd ../pokefirered
+    cd ../pokefirered
 
 To build **pokefirered.gba**:
 
-	make -j$(nproc)
+    make -j$(nproc)
 
 To confirm it matches the official ROM image while building, do this instead:
 
-	make compare -j$(nproc)
+    make compare -j$(nproc)
 
 If only `.c` or `.s` files were changed, turn off the dependency scanning temporarily. Changes to any other files will be ignored and the build will either fail or not reflect those changes.
 
-	make -j$(nproc) NODEP=1
+    make -j$(nproc) NODEP=1
