+Import the `additionalFiles` build extension and use it in your `trigger.config.ts` file:
+
+```ts
+import { defineConfig } from "@trigger.dev/sdk/v3";
+import { additionalFiles } from "@trigger.dev/build/extensions/core";
+
+export default defineConfig({
+  project: "<project ref>",
+  // Your other config settings...
+  build: {
+    extensions: [
+      additionalFiles({ files: ["wrangler/wrangler.toml", "./assets/**", "./fonts/**"] }),
+    ],
+  },
+});
+```
+
+This will copy the files specified in the `files` array to the build directory. The `files` array can contain globs. The output paths will match the path of the file, relative to the root of the project.
+
+This extension effects both the `dev` and the `deploy` commands, and the resulting paths will be the same for both.
+
+<Note>The root of the project is the directory that contains the trigger.config.ts file</Note>

+Import the `additionalPackages` build extension and use it in your `trigger.config.ts` file:
+
+```ts
+import { defineConfig } from "@trigger.dev/sdk/v3";
+import { additionalPackages } from "@trigger.dev/build/extensions/core";
+
+export default defineConfig({
+  project: "<project ref>",
+  // Your other config settings...
+  build: {
+    extensions: [additionalPackages({ packages: ["wrangler"] })],
+  },
+});
+```
+
+This allows you to include additional packages in the build that are not automatically included via imports. This is useful if you want to install a package that includes a CLI tool that you want to invoke in your tasks via `exec`. We will try to automatically resolve the version of the package but you can specify the version by using the `@` symbol:
+
+```ts
+import { defineConfig } from "@trigger.dev/sdk/v3";
+
+export default defineConfig({
+  project: "<project ref>",
+  // Your other config settings...
+  build: {
+    extensions: [additionalPackages({ packages: ["wrangler@1.19.0"] })],
+  },
+});
+```
+
+This extension does not do anything in `dev` mode, but it will install the packages in the build directory when you run `deploy`. The packages will be installed in the `node_modules` directory in the build directory.

+You can install system packages into the deployed image using the `aptGet` extension:
+
+```ts
+import { defineConfig } from "@trigger.dev/sdk/v3";
+import { aptGet } from "@trigger.dev/build/extensions/core";

+});
+```
+
+If you want to install a specific version of a package, you can specify the version like this:
+
+```ts
+import { defineConfig } from "@trigger.dev/sdk/v3";
+
+export default defineConfig({
+  project: "<project ref>",
+  // Your other config settings...

+
+Previously, we installed [Audio Waveform](https://github.com/bbc/audiowaveform) in the build image. That's been moved to a build extension:
+
+```ts
