+# Hardcoded Resources
+
+Files in this folder can be hardcoded into every build. If updating should populate via
+
+```sh
+yarn ts-node tools/workflows/populateResourceContents.ts --skip-nx-cache
+```
+
+## Previewing Changes
+
+By default resources only update on new version release. This can temporarily be bypassed by commenting out the corresponding service code
+
+```ts
+const assetsCacheVersion = this.getAssetResourcesVersion();
+if (assetsCacheVersion === APP_VERSION.number) {
+  return;
+}
+```
