# TYPO3 administration {#typo3-administration}

**Installation**

Learn about the different ways to install TYPO3 and choose the method
that best matches your technical requirements and experience level.

-   [TYPO3 installation overview](https://docs.typo3.org/permalink/t3coreapi:installation-index@13.4)
-   [Composer-based](https://docs.typo3.org/permalink/t3coreapi:installation-composer@13.4)

**Deployment**

The deployment guide highlights some of solutions available that can
help automate the process of deploying TYPO3 to
a remote server.

-   [Configuring environments](https://docs.typo3.org/permalink/t3coreapi:environment-configuration@13.4)
-   [CI/CD and Automatic deployment](https://docs.typo3.org/permalink/t3coreapi:ci-cd-for-typo3-projects@13.4)

**Production environment**

This chapter contains information on how to configure and optimize the infrastructure
running TYPO3 for production.

**[Running TYPO3 in Docker](https://docs.typo3.org/permalink/t3coreapi:admin-docker-index@13.4)**

Learn how to run TYPO3 using Docker containers for local development and testing,
including step-by-step guides for plain Docker, Docker Compose, and DDEV.

**Directory structure**

The folder layout of your TYPO3 project depends on how TYPO3 was installed.
Composer-based installations use a modern structure that separates code from
public files—ideal for deployment workflows and version control. Classic mode
keeps everything in a single folder and is easier to set up for beginners.

Both methods are fully supported for production use, however there are
security consideration regarding
[file access](https://docs.typo3.org/permalink/t3coreapi:security-restrict-access-server-level@13.4)
when using the classic structure.
