+# Homework 6 Template
+
+## Getting started
+
+1.  Fork a repository for yourself with the github `Fork` button.
+
+1.  Clone your repository to your local machine.
+
+1.  If command line utility `gcloud` is not available, download and install
+    [Google Cloud SDK](https://cloud.google.com/sdk/docs/quickstarts) (Japanese
+    guides evailable).
+
+    -   Then install App Engine components for the programming language of your
+        choice.
+        -   Go: `gcloud components install app-engine-go`
+        -   Python: `gcloud components install app-engine-python
+            app-engine-python-extras`
+    -   Run `gcloud init` to initialize the SDK and create a new Cloud Platform
+        project. This newly created Cloud Platform project will allow you to try
+        many Google Cloud Platform products, but we will only use Google App
+        Engine for this homework.
+    -   If you already have Google Cloud SDK installed, run `gcloud components
+        update` to update to the latest version.
+
+1.  Start a local App Engine server with `dev_appserver.py go/` or
+    `dev_appserver.py python-flask/` (depending on whether you're using Go or
+    Python).
+
+1.  Add functionality and test your app by viewing the local instance at
+    http://localhost:8080.
+
+1.  Deploy your app to App Engine with `gcloud app deploy go/` or `gcloud app
+    deploy python-flask/`.
+
+    -   The first time you deploy an App Engine app to your Cloud Platform
+        project, you will be asked to select a region for the location of your
+        App Engine app. Select `asia-northeast1` (Tokyo), `asia-northeast2`
+        (Osaka) or
+        [a region](https://cloud.google.com/compute/docs/regions-zones/) that is
+        close to you.
+    -   Use `--version` flag to specify a version string manually, e.g. `gcloud
+        app deploy python-flask/ --version=python-flask-20190612`.
+
+1.  Test your app in production by accessing the target url shown in the command
+    line console. To access a specific app version, use
+    `https://{VERSION}-dot-{PROJECT_NAME}.appspot.com`, e.g.
+    https://python-flask-20190612-dot-my-project-name.appspot.com.
+
+1.  To stream production server logs in the command prompt console, run `gcloud
+    app logs tail -s default`. You can also use
+    [the web console](https://console.cloud.google.com/logs/viewer) to
+    view/stream server logs for debugging and troubleshooting.
+
+1.  `git add .` and `git commit` and `git push` to upload your changes to your
+    GitHub repository.
+
+1.  Send email to the STEP mailing list to show everyone your awesome app!
+
+Feel free to repeat steps 4-10 as much as you like!
