We want to move our hard-coded "Hello world" greeting into Tina, so it can be accessed and edited via the Tina editor, without needing to touch the code.

Before we can do this, we first need to define a Tina schema which will control the "shape" of the data that we will receive from Tina.

1. Go to the /tina/config.ts file and locate the schema field. It should look like this:

This is a sample schema that's provided out-of-the-box, but we're going to build our own.

schema: {
    collections: [
      {
        name: "post",
        label: "Posts",
        path: "content/posts",
        fields: [
          {
            type: "string",
            name: "title",
            label: "Title",
            isTitle: true,
            required: true,
          },
          {
            type: "rich-text",
            name: "body",
            label: "Body",
            isBody: true,
          },
        ],
        ui: {
          // This is an DEMO router. You can remove this to fit your site
          router: ({ document }) => `/demo/blog/${document._sys.filename}`,
        },
      },
    ],
  },

2. Replace the schema with a basic entry that contains a single field for our amazing Hello World message:

schema: {
   collections: [
     {
       name: "my_first_collection",
       label: "My first collection",
       path: "content/first",
       fields: [
         {
           type: "string",
           name: "title",
           label: "Title",
           isTitle: true,
           required: true,
         }
       ],
       // Comment this out for now. We will come back to this later!
       // ui: {
       //   // This is an DEMO router. You can remove this to fit your site
       //   router: ({ document }) => `/demo/blog/${document._sys.filename}`,
       // },
     },
   ],
 },

3. Now a schema has been defined, it's time to add some data to our new CMS schema!

4. Start your app and go to http://localhost:3000/admin/index.html

5. Notice on the left, we now have a "My first collection" menu item!

6. Click on that menu item.

7. Click the "Add Files" button

8. You can see the single field we described in our Schema - the Title field. Add your amazing title "Hello World!" into it.

9. Click "Save"

If we jump back into the code, you will see a new file has been created. Look in content/ and you'll find a first folder, that contains our new markdown content! The first folder is what we defined in our path field in the schema. All content we create in the "My first collection" collection will be created in this directory.
