=== Importing into IntelliJ IDEA
The separate Maven import process that IntelliJ IDEA uses to parse a project structure
requires more memory. Before importing the project, we recommend increasing the memory
allocation in `Preferences | Build, Execution, Deployment | Build Tools | Maven |
Importing`. Set the `VM options for importer` option to `-Xmx2g`.

To open the project in IntelliJ IDEA, select "`File`" -> "`Open`" and then click on the
root `pom.xml`.
**Please, do this first!**
Go to `Preferences | Build, Execution, Deployment | Build Tools | Maven | Importing`
and set `VM options for importer` to `-Xmx2g` to allocate sufficient memory for IntelliJ IDEA's
Maven import process to parse the Spring Boot project structure. _Not doing so could
mean the import fails silently, leaving the project setup incomplete._

For the actual import use "`File`" -> "`Open`" and select the root `pom.xml`, or the
`spring-boot-project/pom.xml` if you only want the Spring Boot project sources.
