 A PaaS system is a complete platform for deploying and running certain types of applications.
 
-* The benefit of using a PaaS system is convenience: developers don't have to worry about the many details of deployment: everything just works.
-* The drawback of using a PaaS system is lack of flexibility: only certain types of applications are supported.

+- The drawback of using a PaaS system is lack of flexibility: only certain types of applications are supported.
 
 As an application grows, it is almost certain to outgrow the capabilities of a PaaS system, leaving no choice but to look for alternatives. A good strategy is to choose the right platform for each component. Some components continue to run on a PaaS system; others run on specialized infrastructure. This strategy can be implemented with Dagger: each component gets its own deployment plan expressed as code, and Dagger glues it all together into a single workflow.

 Most applications don't fit entirely in any major PaaS system. Instead they are deployed by a patchwork of tools, usually glued together by an artisanal script.

 ## Dagger vs. CI (Github Actions, Gitlab, CircleCI, Jenkins, etc.)
 
-*Summary: Dagger can be used with or without a CI system.*
+_Summary: Dagger can be used with or without a CI system._
 
 Dagger is not a replacement for a CI system. It can be used to deploy applications directly from the terminal,
 or automatically as part of a CI script.

-*Summary: Dagger can be used with or without a build system.*
+_Summary: Dagger can be used with or without a build system._
 
 Most deployment workflows involve building: the process of producing executable artifacts from source code. Build systems are highly specific to the type of application, the programming language in use, etc.
