+### ⭐️ Upload large files with Git LFS
 
+If you are using [Git LFS](https://git-lfs.github.com/) as an option to manage files larger than 100MB in your repository, you can push these to the deployed site.
+
+It is expected that you would run your checkout action with `lfs` enabled (see below for an example).
+
+You will also need to make sure that your build tool includes the `.gitattributes` file in its output.
+
+```yaml
+name: GitHub Pages
+
+on:
+  push:
+    branches:
+      - main
+    tags:
+      - 'v*.*.*'
+
+jobs:
+  deploy:
+    runs-on: ubuntu-20.04
+    permissions:
+      contents: write
+    concurrency:
+      group: ${{ github.workflow }}-${{ github.ref }}
