+## How to use
+
+Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:
+
+```bash
+npx create-next-app --example cms-sitefinity cms-sitefinity-app
+```
+
+```bash
+yarn create next-app --example cms-sitefinity cms-sitefinity-app
+```
+
+```bash
+pnpm create next-app --example cms-sitefinity cms-sitefinity-app
+```
+
+## Configuration
+
+### Step 1. Setup the CMS locally (version >=14.27922)
+
+First, [install](https://www.progress.com/documentation/sitefinity-cms/install-sitefinity) and run the CMS Locally.
+
+### Step 2. Import the ready to use dynamic module 'Posts'
+
+For the purpose of this demo a ready to use dynamic module was build containing two types - 'Post' and 'Author'.
+
+In order to install it:
+
+1. Open the CMS Administration under (/Sitefinity)
+2. Open the Export/Import screen under (/Sitefinity/Administration/Packaging)
+3. Click on Import Zip file and import the file from the [sitefinity folder](./sitefinity/SitefinityExport.zip)
+
+### Step 3. Enable the web service
+
+By default the web services are not allowed for anonymous users, so the yhave to be enabled.
+
+Go to /sitefinity/Administration/WebServices and edit the 'Default' web service to allow it to be accessible by 'Everyone'
+
+### Step 4. Install the GraphQL package
+
+1. Add the [Sitefinity CMS nugget source](https://www.progress.com/documentation/sitefinity-cms/sitefinity-cms-nuget-packages-repository)
+2. Install the [Progress.Sitefinity.GraphQL](https://nuget.sitefinity.com/#/package/Progress.Sitefinity.GraphQL) package (enable prerelease filter).
+
+### Step 5. Set up environment variables
+
+Copy the `.env.local.example` file in this directory to `.env.local` (which will be ignored by Git):
+
+```bash
+cp .env.local.example .env.local
+```
+
+Then set each variable on `.env.local`
+
+- `SF_API_URL` - This is the url of the 'Default' web service that we configured earlier. E.g. http://locahost/api/default/
+- `SF_URL` - This is the URL of the CMS itself. E.g. http://localhost/
+
+### Step 6. Run Next.js in development mode
+
+```bash
+npm install
+npm run dev
+
+# or
+
+yarn
+yarn dev
+```
+
+Your blog should be up and running on [http://localhost:3000](http://localhost:3000)! If it doesn't work, post on [GitHub discussions](https://github.com/vercel/next.js/discussions).
