# Installing Aizen

The Aizen installation consists of installing the Aizen infrastructure and then installing the Aizen core components:

* [installing-the-core-components](https://aizen-corp.gitbook.io/docs/installation/installing-aizen/installing-the-core-components "mention")

If you are doing model training on GPU nodes, you will need to install Aizen remote components. See [installing-aizen-remote-components](https://aizen-corp.gitbook.io/docs/installation/installing-aizen-remote-components "mention"). You may also want to install optional components after installing Aizen. See [installing-optional-components](https://aizen-corp.gitbook.io/docs/installation/installing-optional-components "mention").

Before you start the installation, make sure that you meet all hardware requirements (see [hardware-requirements](https://aizen-corp.gitbook.io/docs/installation/setting-up-your-environment/hardware-requirements "mention")) and that you have installed all the required software on your cluster. See [software-requirements](https://aizen-corp.gitbook.io/docs/installation/installing-aizen/software-requirements "mention"). Also, make sure that you have added the Aizen Helm charts and have obtained credentials for the Aizen microservice images. See [#adding-the-aizen-helm-charts](https://aizen-corp.gitbook.io/docs/installation/software-requirements#adding-the-aizen-helm-charts "mention") and [#getting-credentials-for-the-aizen-microservice-images](https://aizen-corp.gitbook.io/docs/installation/software-requirements#getting-credentials-for-the-aizen-microservice-images "mention").
