## Getting Started ## Build
OpenSTA can be run as a [Docker](https://www.docker.com/) container OpenSTA is built with CMake.
or built as local executable with CMake.
### Run using Docker
* Install Docker on [Windows](https://docs.docker.com/docker-for-windows/), [Mac](https://docs.docker.com/docker-for-mac/) or [Linux](https://docs.docker.com/install/).
* Navigate to the directory where you have the input files.
* Run OpenSTA as a binary using
````
docker run -it -v $(pwd):/data openroad/opensta
````
4. From the interactive terminal, use OpenSTA commands. You can read input files from `/data` directory inside the docker container (e.g. `read_liberty /data/liberty.lib`). You can use OpenSTA in non-interactive mode by passing a command file using the `-f` flag as follows.
```
docker run -it -v $(pwd):/data openroad/opensta -f /data/cmd_file
```
Note that the path after `-f` is the path inside container, not on the guest machine.
