+# {project.artifact-id} project
+
+This project uses Quarkus, the Supersonic Subatomic Java Framework.
+
+If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
+
+## Running the application in dev mode
+
+You can run your application in dev mode that enables live coding using:
+```shell script
+{buildtool.cmd.dev}
+```
+
+## Packaging and running the application
+
+The application can be packaged using:
+```shell script
+{buildtool.cmd.package}
+```
+It produces the `{project.artifact-id}-{project.version}-runner.jar` file in the `/{buildtool.build-dir}` directory.
+Be aware that it’s not an _über-jar_ as the dependencies are copied into the `{buildtool.build-dir}/lib` directory.
+If you want to build an _über-jar_, just add the `--uber-jar` option to the command line:
+```shell script
+{buildtool.cmd.package-uberjar}
+```
+
+The application is now runnable using `java -jar {buildtool.build-dir}/{project.artifact-id}-{project.version}-runner.jar`.
+
+## Creating a native executable
+
+You can create a native executable using: 
+```shell script
+{buildtool.cmd.package-native}
+```
+
+Or, if you don't have GraalVM installed, you can run the native executable build in a container using: 
+```shell script
+{buildtool.cmd.package-native-container}
+```
+
+You can then execute your native executable with: `./{buildtool.build-dir}/{project.artifact-id}-{project.version}-runner`
+
+If you want to learn more about building native executables, please consult {buildtool.guide}.

+= Quarkus - Codestarts
+
+This guide explains how to create and configure a Quarkus Codestart for an extension.
+
+== Description
+
+"Codestarts" is the name we gave to our Quarkus quickstart code generation system. 
+Codestarts provide a personalized Quarkus getting started experience and really show the Quarkus breadth.
+A Quarkus extension are able to provide one or more well defined codestarts which will contain the necessary resources and code examples required to get started using that particular extension.
+
+== How it works
+
+There are two kinds of codestarts contributing to the generation of a project, the kind where we want to have only one for a project (called Base) and the rest (called Extra).
+
+Base:
+
+* project: The project skeleton (e.g. a Quarkus project)
+* buildtool: The build tool (e.g. Maven, Gradle, Gradle with Kotlin DSL)
+* language: The coding language (e.g. Java, Kotlin, Scala)
+* config: The config type (e.g. yaml, properties)
+
+Extra:
+
+* tooling: Anything that can be added to improve the project (e.g. dockerfiles)
+* example: Any Quarkus extension can provide example code. The user can decide to activate it or not.
+
+Each codestart consists of:
+
+. A codestart unique name, ie `my-codestart`
+. A directory for the codestart files, ie `my-codestart/`
+. A `codestart.yml` file
+. Optionally some templates which following a common structure and naming conventions
+
+*NOTE* The `codestart.yml` file and the directory structure follow the same principle, it can optionally contain a base and/or some language overrides.
+
+=== Project generation
+
+When generating a Quarkus project:
+
+. Codestarts to use are resolved depending on the input
+. The Codestarts' `shared-data` (defined in the different codestart.yml) is merge together and made available to all codestarts
+. The relevant files are processed:
+** Only the files that are related to the selected language are processed
+** The files are processed differently based on a naming convention.
+** The data is used to render Qute templates
+** We always process in this order: 
+
+. language
+. project
+. buildtool
+. config
+. tooling
+. example
+
+
+The data used to generate a specific codestart is a merge of:
+
+. The data of the codestart to generate
+. All codestarts "shared" data
+. The user input
+. Some specific post processing (e.g. adding dependencies)
+
+*NOTE* The data (shared or not) can also be specific to a language.
+
+=== Directory Structure
+
+*NOTE* `codestart.yml` is the only required file.
+
+* `codestart.yml` must be at the root of the codestart
+* `./base` contains all the files that will be processed
+* `./[languageName]` contains all the files that will be processed if the specified language has been selected (overriding base)
+
+=== codestart.yml
+
+codestart.yml:
+[source,yaml]
+----
+name: the unique name - REQUIRED
+ref: the reference name (not unique) to use for extension matching (else the name is used)
+type: the type [example (default), project, buildtool, language, config] or any custom type
+fallback: flag to indicate that it should be selected as fallback when no codestart has been selected with type - Only for base types
+preselected: flag to indicate that it should be pre-selected - Only for extra types.
+spec:
+  [base or language name]: the specification (base, java, ...)
+    data: a map of data to use only for this codestart
+    shared-data: a map of data to use accross all codestarts
+    dependencies: a list of dependencies to add when this is selected
+    test-dependencies: a list of test dependencies to add when this is selected
+----
+
+=== Naming Convention for files
+
+* `.tpl.qute` will be processed with Qute (`.tpl.qute` will be removed from the output file name).
+* `.include.qute` is used as a Qute template for inclusion (only available to the codestart, not listed in the generated project ).
+
+  Example: When using `{#include [name]}` in a template, it will look for `[name].include.qute` in the language dir, then in the base dir or the codestart.
+
+* an output strategy can be defined for specific files, it defines some specific logic on how to deal with those files.
+
+ Example: in the Quarkus project `codestart.yml`:
+[source,yaml]
+----
+output-strategy:
+  "pom.xml": smart-pom-merge # smartly merge pom.xml contents together
+  "README.md": append # they are appended together
+  "readme.md": forbidden # it will fail if found in any codestart
+  "README.adoc": forbidden
+  "readme.adoc": forbidden
+  ".gitignore": append
+  "src/main/resources/application.yml": smart-config-merge # smartly merge config together and automatically converted to the selected config type (yaml or properties)
+  "src/main/resources/application.yaml": forbidden # should use yml instead
+  "src/main/resources/application.properties": forbidden # should use yml instead
+  "*": fail-on-duplicate # it will fail if a duplicate is found for all other files
+----
+
+* other files are just copied as is.
+
+
+=== Writing Example Code for an Extension
+
+Let's imagine we are writing the example codestart for my "foo" extension. As we discussed before, the base of the project is already provided so we can focus on the example code.
+
+1. Create your `codestart.yml`:
+
+codestart.yml:
+[source,yaml]
+----
+---
+name: foo-example
+ref: foo
+type: example
+missing-languages:
+  - kotlin
+  - scala
+spec:
+  base:
+    data:
+      # Some data for my templates which gives could be overridden by the user input
+      some:
+        data:
+          here: bar
+          there: foo
+    dependencies:
+      # the dependencies needed for my codestart (note that the extension dependency is auto-added if missing)
+      - io.quarkus:quarkus-foo
+      - io.quarkus:quarkus-resteasy
+      # ... you can also provide a version (when it's not part of the platform bom)
+      - group:artifact:version
+    test-dependencies:
+      # test dependencies
+      - io.rest-assured:rest-assured
+----
+
+*NOTE* You don't need to add `pom.xml` or `build.gradle`, it is going to be auto generated. It will include the dependencies provided in the `codestart.yml`.
+
+2. Add you example code in java, kotlin or scala
+
+* java/src/main/java/org/acme/foo/Foo.java:
+[source,java]
+----
+package org.acme.foo
+
+import javax.ws.rs.GET
+import javax.ws.rs.Path
+import javax.ws.rs.Produces
+import javax.ws.rs.core.MediaType
+
+@Path("foo")
+class ExampleResource {
+
+    @GET
+    @Produces(MediaType.TEXT_PLAIN)
+    fun hello() = "Hello foo"
+}
+----
+
+* kotlin/src/main/kotlin/org/acme/foo/Foo.kt
+* scala/src/main/scala/org/acme/foo/Foo.kt
+
+*NOTE* Just add `.tpl.qute` if you want it to be rendered with qute and use some data and simple logic
+
+*NOTE* Most of the time you won't need it for code, but you can use a `base` directory to add files to process for all languages.
+
+
+2. Add some configuration (if needed)
+
+The `base/src/main/resources/application.yml` file is going to be merged with the other codestarts config and automatically converted to the selected config type (yaml or properties).
+
+Note: if it's specific to a language, you can put the config in each languages folders
+
+* base/src/main/resources/application.yml (using quarkus yaml config convention):
+[source,yaml]
+----
+quarkus:
+  http:
+    port: 8081
+----
+
+3. Create a readme section (if needed)
+
+This will be appended to all different selected examples.
+
+* base/README.md
+[source,markdown]
+----
+# FOO Example
+
+The Foo Example shows...
+----
+
+=== Tips for writing extension example code
+
+- Your example must/should be independent from buildtool and dockerfiles
+- Use the package `org.acme.[unique-name]` for your sources.
+- Use the path `/unique-name/...` for your REST paths
+- Write tests for your examples
+- Examples in different codestarts must be independent, only the config and the build file are merged.
+- Write the config in `src/main/resources/application.yml`.
+It is going to be merged with the other codestarts config and automatically converted to the selected config type (yaml or properties).
+- you can add languages independently
+
+== Problems to solve
+
+- How to test that (in combinations)?
+- Dependencies conflicts?
+- Config conflicts?
+- Versioning?
+- Dynamic paths for dynamic package names (should or should not do)?
+    - `/{project.package-name}` or auto-replace `org.acme`
+- We could add `foo.data.qute` processed and made available in data `foo` as a collection to other templates

-# ${project_artifactId} project
-
-This project uses Quarkus, the Supersonic Subatomic Java Framework.
-
-If you want to learn more about Quarkus, please visit its website: https://quarkus.io/ .
-
-## Running the application in dev mode
-
-You can run your application in dev mode that enables live coding using:
-```
-./gradlew quarkusDev
-```
-
-## Packaging and running the application
-
-The application can be packaged using `./gradlew quarkusBuild`.
-It produces the `${project_artifactId}-${project_version}-runner.jar` file in the `build` directory.
-Be aware that it’s not an _über-jar_ as the dependencies are copied into the `build/lib` directory.
-
-The application is now runnable using `java -jar build/${project_artifactId}-${project_version}-runner.jar`.
-
-If you want to build an _über-jar_, just add the `--uber-jar` option to the command line:
-```
-./gradlew quarkusBuild --uber-jar
-```
-
-## Creating a native executable
-
-You can create a native executable using: `./gradlew build -Dquarkus.package.type=native`.
-
-Or, if you don't have GraalVM installed, you can run the native executable build in a container using: `./gradlew build -Dquarkus.package.type=native -Dquarkus.native.container-build=true`.
-
-You can then execute your native executable with: `./build/${project_artifactId}-${project_version}-runner`
-
-If you want to learn more about building native executables, please consult https://quarkus.io/guides/gradle-tooling#building-a-native-executable.
