+= {project-name} - Live Coding
+
+One of the major productivity problems that face most Java developers is traditional Java
+development workflow. For most web developers this will generally be:
+
+_Write Code_ -> _Compile_ -> _Deploy_ -> _Refresh Browser_ -> _Repeat_
+
+This can be a major drain on productivity, as the compile + redeploy cycle can often take
+up to a minute or more. {project-name} aims to solve this problem with its _Live Coding_
+feature. When running in development mode the workflow is simply:
+
+_Write Code_ -> _Refresh Browser_ -> _Repeat_
+
+This will work out of the box, with no special setup required. This works for Java file, application config,
+and static resources.
+
+== How it works
+
+When you run `mvn compile quarkus:dev` {project-name} will launch in development mode. When
+it receives a HTTP request it will hold the request, and check to see if any application source
+files have been changed. If they have it will transparently compile the changed files, redeploy
+the application with the changed files, and then the HTTP request will continue to the redeployed
+application. {project-name} redeploys are much faster than a traditional app server, so for all but the largest
+applications this should take well under a second.
