+# Building
+
+Resourcify uses stonecutter to compile against multiple Minecraft versions and loaders at once, this changes a bit about
+how the mod is built. For more info about stonecutter, see their [wiki](https://stonecutter.kikugie.dev/).
+
+Before your first build you need to run the following command to put the access wideners in the correct places, you will
+need to run this every time you update an access widener.
+
+```shell
+./gradlew setupChiseledBuild
+```
+
+Then to build the mod run the following command, the mod jars will be in the `jars` folder after the build has finished.
+
+```shell
+./gradlew chiseledBuild
+```
