  +You'll need Docker installed and running to use this. You will also need to build the container located at `packages/techdocs-container` under the tag `mkdocs:local-dev` (for now until we deploy the container to a centralized Docker registry), as you can see in the commands from below:
  ```bash
  docker build packages/techdocs-container -t mkdocs:local-dev
  ```
  -Once that is built, you'll need to manually create an `alias` for running the CLI locally:
  -
  -```bash
  -cd packages/techdocs-cli
  -echo "$(pwd)/bin/techdocs"
  -
  -# Copy the value from above and add it in [HERE] below
  -# For more convenience, add it to your ~/.zshrc or ~/.bash_profile
  -# otherwise you'll lose it when you open a new Terminal
  -alias techdocs="[HERE]"
  -```
  -
  -From that point, you can invoke `techdocs` from any project with a docs folder. Try out our example!
  -
  ```bash
  cd packages/techdocs-container/mock-docs
  -techdocs serve
  +npx techdocs serve
  ```
  You should have a `localhost:3000` serving TechDocs in Backstage, as well as `localhost:8000` serving Mkdocs (which won't open up and be exposed to the user).
