+# Generators
+
+Generators are functions which return a promise that resolves once the generator
+has finished its scaffolding work.
+
+> **Note:** By the term *generator* we refer to a design concept within this project,
+not to the JavaScript language feature with the same name.
+
+## Writing generators
+
+Generator logic typically comprises a few common logical steps:
+
+- Ask questions (interactive dialog)
+- take an answer object and create a context-object
+    - with an `answers` key pointing on the user's answer object. If necessary derive further answers or transform existing answers.
+    - optional: with config keys for subsequent tasks
+- copy a template folder using `copyTemplate` task. Any `<%= ... %>` placeholders will be matched against `answers` and replaced if a key with the same name exists.
+- optional: process snippet comments in selected source or config files to insert statements based on user answers. Any `{{ ... }}` placeholders will be mateched against `answers` and replaced if a key with the same name exists.
+
+We use [inquirer](github.com/) to ask questions. Answers will be written into
+properties of an answer object.
+
+```javascript
+ return inquirer.prompt([
+        {type: "input",   name: "workspace", message: "Workspace:"},
+        {type: "input",   name: "proj_name", message: "Project name (kebab-case):"},
+ ])
+ .then((answers) => {
+    // map / compute further answers ...
+    // configure subsequent processing steps
+    let context = {
+        answers: answers,
+        copyTemplate: {
+            //...
+        },
+        processSnippets: {
+            // ...
+        }
+    }
+    return context;
+ })
+ .then(copyTemplate)
+ .then(processSnippets);
+```

-Based on answers by a user we may compute further answers. Computation and mapping
-happens inside the inquirer callback prior to copying and processing the templates.
-When all answers are computed a template can be copied and placeholders
-replaced.
