## Implementation details
For `amd64`, prebuilt images are used everywhere (because all images are available for this architecture).
For `amd64`, prebuilt container images (see the [container images we use](container-images.md)) are used everywhere, because all images are available for this architecture.
For other architectures, components which have a prebuilt image make use of it. If the component is not available for the specific architecture, [self-building](self-building.md) will be used. Not all components support self-building though, so your mileage may vary.

**Caution: self-building does not have to be used on its own. See the [Alternative Architectures](alternative-architectures.md) page.**
The playbook supports the self-building of various components, which don't have a container image for your architecture. For `amd64`, self-building is not required.
The playbook supports self-building of various components, which don't have a container image for your architecture (see the [container images we use](container-images.md)). For `amd64`, self-building is not required.
For other architectures (e.g. `arm32`, `arm64`), ready-made container images are used when available. If there's no ready-made image for a specific component and said component supports self-building, an image will be built on the host. Building images like this takes more time and resources (some build tools need to get installed by the playbook to assist building).
To make use of self-building, you don't need to do anything besides change your architecture variable (e.g. `matrix_architecture: arm64`). If a component has an image for the specified architecture, the playbook will use it. If not, it will build the image.
To make use of self-building, you don't need to do anything besides change your architecture variable (e.g. `matrix_architecture: arm64`). If a component has an image for the specified architecture, the playbook will use it directly. If not, it will build the image on the server itself.
Note that **not all components support self-building yet**.
List of roles where self-building the Docker image is currently possible:
- `matrix-synapse`
- `matrix-synapse-admin`
