+1. Read the [Hacktoberfest guide](https://hacktoberfest.com/participation/).
+2. Check the [documentation](https://www.axemsolutions.io/dem_doc/index.html) and try out DEM to get 
+familiar with the tool.
+3. Look for issues with the `hacktoberfest` label in the 
+[issue tracker](https://github.com/axem-solutions/dem/issues).
+4. Read the [Code of Conduct](https://github.com/axem-solutions/dem?tab=coc-ov-file#readme) and the 
+[Contribution Guide](https://github.com/axem-solutions/.github/blob/4bdc1be72b0a2c97da19408c59d6dd5d1845a469/CONTRIBUTING.md).

 ## The Concept in a Nutshell
 A set of software tools used for a specific development project is called a Development Environment.
 These tools for example can be the build system, debugger, test framework, etc...  
 
 The idea is to pack the tools separately into container images, which are then can be stored in 
 registries.
 
+> How is DEM different from other container-based development environments?  
+Instead of putting all the tools into a single image and then the user must enter the container 
+using an interactive shell, DEM creates a separate one for each tool. This means the user can work 
+on their host system, with their usual setup, but the Development Environment specific tools are 
+isolated in containers.
+
 Each Development Environment has a descriptor. A descriptor, like a blueprint, indicates which tools 
 are required in the project, and the place their container images are stored.
