Before we can build & test our example app with `dagger`, we need to have Docker running.
You most likely already have Docker set up.
If not, [Docker Desktop](https://www.docker.com/products/docker-desktop) makes this easy.
With Docker running, we are ready to download our example app and run its CI/CD pipeline.
Still in your `Command Prompt` terminal:
```shell
git clone https://github.com/dagger/dagger
cd dagger
git checkout v0.2.0
cd pkg/universe.dagger.io/examples/todoapp
```
With everything in place, we run the CI/CD pipeline locally:
```shell
dagger do build
```
With an empty cache, installing all dependencies, then testing & generating a build for this example app completes in just under a minute:
```shell
[✔] client.filesystem.".".read 0.2s
[✔] actions.deps 55.2s
[✔] actions.test.script 0.1s
[✔] actions.test 1.8s
[✔] actions.build.run.script 0.1s
[✔] actions.build.run 8.6s
[✔] actions.build.contents 0.4s
[✔] client.filesystem.build.write 0.2s
```
Since this is a static application, we can open the files which are generated in `actions.build.contents` in a browser.
The last step copies the build result into the `build` directory on the host.
On Windows, we run `start build/index.html` in our `Command Prompt` terminal and see the following app preview:
![todoapp preview](/img/getting-started/todoapp.png)
One of the big advantages to this approach is that we did not have to install any dependencies specific to this application.
Dagger managed all the intermediary steps, and we ended up with the end-result on our host, without any of the transient dependencies.
Now that we have everything running locally, let us make a change and get a feel for our local CI/CD loop.
The quicker we can close this loop, the quicker we can learn what actually works.
With Dagger, we can close this loop locally, without committing and pushing our changes.
And since every action is cached, subsequent runs will be quicker.
In the todoapp directory, edit line `25` of `src/components/Form.js` and save the file.
I change this line to `What must be done today?` and run the build locally again:
```shell
dagger do build
INF upgrading buildkit have host network=true version=v0.10.0
[✔] client.filesystem.".".read 0.1s
[✔] actions.deps 15.0s
[✔] actions.test.script 0.0s
[✔] actions.test 1.8s
[✔] actions.build.run.script 0.0s
[✔] actions.build.run 8.9s
[✔] actions.build.contents 0.4s
[✔] client.filesystem.build.write 0.1s
```
Being able to re-run the test & build loop locally in `26.3s`, without adding any extra dependencies to our host, is likely to change our approach to iterating on changes.
It becomes even more obvious when the change is not as straightforward as knowing _exactly_ which line to edit.
