The flow performs all ASIC implementation steps from RTL all the way down to GDSII.\n\nYou can check out the documentation, including in-depth guides and reference manuals at [ReadTheDocs](https://openlane.readthedocs.io/).\n\n## Installation, the short version\nThe short version is, to install the OpenLane environment...\n\n\u003e On Windows, install and launch the [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install) before doing anything. We recommend and provide instructions for Ubuntu 20.04.\n\n\u003e On macOS, get [brew](https://brew.sh).\n\n1. [Get Docker](https://docs.docker.com/get-docker/) (or a compatible container engine)\n    * On Ubuntu, follow the [Docker post install instructions](https://docs.docker.com/engine/install/linux-postinstall/) after you install Docker.\n2. Get Python 3.6 or higher ([macOS](https://formulae.brew.sh/formula/python3) | [Ubuntu](https://packages.ubuntu.com/focal/python3))\n    * On Ubuntu, you may also need to install venv: `apt-get install python3-venv`\n3. Get git ([macOS](https://formulae.brew.sh/formula/git) | [Ubuntu](https://packages.ubuntu.com/focal/git))\n4. Get GNU Make ([macOS](https://formulae.brew.sh/formula/make) | [Ubuntu](https://packages.ubuntu.com/focal/make))\n\n\nRun the following commands in your command-line prompt:\n\n```sh\ncd $HOME\ngit clone https://github.com/The-OpenROAD-Project/OpenLane\ncd OpenLane\nmake\nmake test\n```\n\nIf everything's gone smoothly, that's it. OpenLane is set up on your computer. To enter the OpenLane environment, `cd $HOME/OpenLane` and then `make mount`.\n\n## Installation, the long version\nSee the installation docs at https://openlane.readthedocs.io/en/latest/getting_started/installation/index.html.\n\n## Usage\nAfter entering the OpenLane environment, you can start hardening chips: the following command, for example, runs the included [spm design](./designs/spm).\n\n```sh\n./flow.tcl -design spm\n```\n\n## Need more help?\nYou can join the [Open Source Silicon Slack](https://invite.skywater.tools), where you can ask thousands of other open source hardware enthusiasts for help with setting up or running OpenLane.\n\n## Publication\nIf you use OpenLane in your research, please cite the following paper.\n\n* M.
