# OpenTitan

This repository contains hardware, software and utilities written as part of the
OpenTitan project. It is structured as monolithic repository, or "monorepo",
where all components live in one repository.

## Documentation

The project contains comprehensive documentation of all IPs and tools. You can
either access it [online](https://docs.opentitan.org/) or build it
locally by following the steps below.

1. Download and install [`hugo-extended`](https://gohugo.io/getting-started/installing/).

2. Ensure that you have the required Python modules installed (to be executed
in the repository root):

```command
$ sudo apt install python3 python3-pip
$ pip3 install --user -r python-requirements.txt
```

3. Execute the build script:

```command
$ ./util/build_docs.py --preview
```

This compiles the documentation into `./build/docs` and starts a local
server, which allows you to access the documentation at
[http://127.0.0.1:1313](http://127.0.0.1:1313).
