+### Embedding ToS checkbox
+
+A ToS acceptance checkbox can be added to any release page to gate binary
+downloads behind a user acknowledgement. The feature is opt-in per page.
+
+**1. Add the checkbox macro** above the content you want to protect:
+
+```md
+{{ tos_checkbox("unique-section-id") }}
+```
+
+**2. Wrap the protected content** in an HTML div with a matching `id`:
+
+```md
+<div id="unique-section-id" class="tos-gate-content" markdown="1" style="display: none">
+
+...binary download buttons and related content...
+
+</div>
+```
+
+`tos_checkbox` accepts an optional `tos_url` argument to override the default
+Terms of Service link:
+
+```md
+{{ tos_checkbox("unique-section-id", tos_url="https://example.com/terms") }}
+```
+
+For pages with multiple release sections, use a distinct `section-id` per
+release (e.g. `vendor-board-v100-binaries`, `vendor-board-v090-binaries`). See
+[`docs/variants/gigabyte_mz33-ar1/releases.md`][tos-example] for example.

 ## Building
 
-!!! Error "STOP"
+To build Dasharo (coreboot+UEFI) firmware image, first clone the coreboot
+repository:
 
-    Building the firmware from source is currently only available after
-    purchasing the product from [our
-    shop](https://shop.3mdeb.com/product/full-build-gigabyte-mz33-ar1-with-dasharo-corebootuefi-pro-package-for-servers/)
-    and agreeing to the terms of service.
+```bash
+git clone https://github.com/Dasharo/coreboot.git
+```
+
+then follow the steps below:
+
+1. To build a specific version checkout to the version's tag.
+    Skip this step otherwise.
+
+    ```bash
+    cd coreboot
+    git checkout gigabyte_mz33_ar1_<version>
+    ```
+
+    For example
+
+    ```bash
+    git checkout gigabyte_mz33_ar1_v0.9.0
+    ```
+
+2. Checkout submodules:
+
+    ```bash
+    git submodule update --init --checkout
+    ```
+
+3. Download the package with necessary blobs and put it in proper directory:
+
+{{ tos_checkbox("gigabyte-mz33-ar1-v090-blobs") }}
+
+<div id="gigabyte-mz33-ar1-v090-blobs"
+     class="tos-gate-content" markdown="1"
+     style="display: none">
+
+- Download the [blobs
+package](https://dl.3mdeb.com/open-source-firmware/Dasharo/gigabyte_mz33_ar1/uefi/v0.9.0/Turin.zip).
+- Then unzip it to the following directory:
+
+    ```bash
+    unzip Turin.zip -d 3rdparty/blobs/soc/amd/
+    ```
+
+</div>
+
+Now build the firmware:
+
+```bash
+./build.sh mz33_ar1
+```
+
+The resulting coreboot image will be placed in the coreboot directory as
+`asrock_spc741d8_<version>.rom` and
