+
+Follow the *[Get Stared](../../get-started/microservice.md)* guide to create a new layered web application with the following configuration:
+
+* **Solution name**: `CloudCrm`
+* **UI Framework**: ASP.NET Core MVC / Razor Pages
+* **Database Provider**: Entity Framework Core
+* **Public website**: Selected
+
+You can select the other options based on your preference.
+
+> **Please complete the [Get Stared](../../get-started/layered-web-application.md) guide and run the web application before going further.**
+
+The initial solution structure should be like the following in ABP Studio's *[Solution Explorer](../../studio/solution-explorer.md)*:
+
+![abp-studio-solution-explorer-initial-cloud-crm-microservice-solution](images/abp-studio-solution-explorer-initial-cloud-crm-microservice-solution.png)
+
+> ABP Studio will perform a few additional steps after creating your solution. **Please wait until all the background tasks are completed** before going further.
+
+Initially you see three folders (`apps`, `gateways` and `services`) and ~10 ABP Studio modules (depends on your preferences while creating the solution) under the `CloudCrm` ABP Studio solution. Some of these modules represent microservices, some of them represent web applications and some others represent API gateways in our system.
+
+> An **ABP Studio module** is typically a .NET solution and an **ABP Studio solution** is an umbrella concept for multiple .NET Solutions (see the *[Concepts](../../studio/concepts.md)* document for more).
+
+You can see the *[Microservice Solution Template](../../solution-templates/microservice/index.md)* document later if you want to understand the initial solution structure with all its details. However, it is not needed to follow this tutorial.
+
+## Summary
+
+In this part, you've created the initial microservice solution which already contains a few infrastructure services. We will create our first business service in the [next part](part-02.md).
