A walkthrough and more details are available on Google Drive SDK docs.

1. Download and install ASP.NET MVC 3.

2. Configure IIS (or another web server) to publish your ASP.NET application to a publicly-accessible URI (e.g. http://www.example.com).

3. Clone DrEdit's git repo and init submodules:

   git clone [email protected]:googledrive/dredit.git && cd dredit
   git submodule init
   git submodule update --recursive
   

4. Create an API project in the Google APIs Console.

5. Select the Services tab in your API Project, and enable the Drive API and Drive SDK.

6. Select the API Access tab in your API Project, click Create an OAuth 2.0 client ID.

7. In the Branding Information section, provide a name for your application (e.g. "DrEdit"), and click Next. Providing a product logo or a homepage URL is optional.

8. In the Client ID Settings section, do the following:

   1. Select Web application for the Application type
   2. Click the more options link next to the heading, Your site or hostname.
   3. List the hostname of the web server configured in step 2 in the Authorized Request URIs and JavaScript Origins fields.
   4. Click Create Client ID.

9. Register DrEdit as described in Enable the Drive SDK using the following values:

   1. Set the default MIME types text/plain and text/html, and the default extensions txt and html.
   2. Ensure that the set of redirect URIs includes the URI of your web server. The same URL must be provided for the Open URL and Create URL fields.
   3. Add the Google API Scopes of https://www.googleapis.com/auth/userinfo.email, https://www.googleapis.com/auth/userinfo.profile and https://www.googleapis.com/auth/drive.install.
   4. For icons, use the example icons provided in the chromewebstore directory.

10. Open the dotnet\DrEdit.sln solution in Visual Studio.

11. Edit Models\ClientCredentials.cs and replace CLIENT_ID, CLIENT_SECRET and REDIRECT_URI with the values from the Google APIs Console under the API Access tab for the project.

12. Edit Scripts\app.js and replace YOUR_APP_ID with the value of the CLIENT_ID from the Google APIs Console under the API Access tab for the project.

13. Build the solution and deploy it on the web server configured in step 2.

14. Test the app by browsing to the web server URI (e.g. http://www.example.com).
