  title: Running Backstage Locally
  ---
  +## Prerequisites
  +
  +- Node.js
  +
  First make sure you are using NodeJS with an Active LTS Release, currently v12.
  This is made easy with a version manager such as
  [nvm](https://github.com/nvm-sh/nvm) which allows for version switching.
  ```bash
  -# Checking your version
  -node --version
  -> v14.7.0
  -
  -# Adding a second node version
  +# Installing a new version
  nvm install 12
  > Downloading and installing node v12.18.3...
  > Now using node v12.18.3 (npm v6.14.6)
  +
  +# Checking your version
  +node --version
  +> v12.18.3
  ```
  +- yarn
  +
  +Please refer to the
  +[installation instructions for yarn](https://classic.yarnpkg.com/en/docs/install/).
  +
  +- Docker
  +
  +We use Docker for few of our core features. So, you will need Docker installed
  +locally to use features like Software Templates and TechDocs. Please refer to
  +the
  +[installation instructions for Docker](https://docs.docker.com/engine/install/).
  +
  +## Clone and Build
  +
  To get up and running with a local Backstage to evaluate it, let's clone it off
  of GitHub and run an initial build.
