You can also speed up your launch time by pre-building your Docker Containers with GitHub Actions, so that Binder is only pulling the container and not forced to a full build.

You can use the [repo2docker action](https://github.com/machine-learning-apps/repo2docker-action) to accomplish this, particularly you want to set the option `MYBINDERORG_CACHE: true`

An example would be to drop the following file `.github/workflows/binder.yaml` into your repo:

```auto
name: Build Notebook Container
on: [push] # You may want to trigger this Action on other things than a push.
jobs:
  build:
    runs-on: ubuntu-latest
    steps:

    - name: checkout files in repo
      uses: actions/checkout@master

    - name: update jupyter dependencies with repo2docker
      uses: machine-learning-apps/repo2docker-action@master
      with:
        DOCKER_USERNAME: ${{ secrets.DOCKER_USERNAME }}
        DOCKER_PASSWORD: ${{ secrets.DOCKER_PASSWORD }}
        MYBINDERORG_CACHE: true

```

This will **offload the building of Docker Images on GitHub entirely, thus speeding up your Binder launches incredibly**.

How does this work? See the [README](https://github.com/machine-learning-apps/repo2docker-action).

Please let me know if there are any questions.
