-# concept
-
-The concept behind coursebuilder is to store curricula descriptions in `YAML` files that can be versioned in a git repository. Unlike classic databases, an observable and well defined versioning is paramount in these descriptions as they are the legal foundation for study and exam regulations.
-
-The following pieces play together here:
-
-- `schema` files, usually a `schema.yaml`
-- `mod` files, usually something along the lines of `mod.coursecode.yaml`
-- `book` files describing a whole regulation set and course global details
-- some sort of transformation with `coursebuilder` into Markdown that is piped through [pandoc](https://pandoc.org) in order to generate PDF, HTML and other representation from this code
-
-# schema files
-
-Schema files are responsible to describe the used structures in a database. The following datatypes are supported:
-
-- `str` a simple string, can be accompanied with a `template`
-- `enum` a classic enum datatype with a fixed set of values
-- `num` a numeric datatype
-- `multinum` an array type with the possibility to `spec` each value
-- `multikey` a key-value type with additional numeric data associated with each key instance
-
-# mod files (modules)
-
-Modules describe a course in detail and implement an instance of the schema file. Especially `strings` and `enums` are translatable One of the plan is to use a validator to find inconsistencies automatically, like workloads that are not following the 30h = 1ECTS rule.
-
-
-# datatypes
-
-## `str` datatype
-
-```yaml
-# this would reside in a schema field on top level
-# a field of name 'id'
-id: # name of the field
-    type: str # sets the datatype to str
-    translatable: false # enforces the value is not translatable (default is true)
-    label: { # label describes the meaning of the datatype in regards of the schema
-        de: "Kürzel",   # translation of the label in German (de)
-        en: "code" # translation of the label in English (en)
-    }

-      **What is it**
-
-      Lorem Ipsum is simply dummy text of the printing and typesetting 
-      industry. Lorem Ipsum has been the industry's standard dummy text 
-      ever since the 1500s, when an unknown printer took a galley of type 
-      and scrambled it to make a type specimen book. It has survived not only 
-      five centuries, but also the leap into electronic typesetting, remaining 
-      essentially unchanged. It was popularised in the 1960s with the release 
-      of Letraset sheets containing Lorem Ipsum passages, and more recently with
-      desktop publishing software like Aldus PageMaker including versions of 
-      Lorem Ipsum.

-      **Where did it come from**
-
-      Contrary to popular belief, Lorem Ipsum is not simply random text. 
-      It has roots in a piece of classical Latin literature from 45 BC, 
-      making it over 2000 years old. Richard McClintock, a Latin professor 
-      at Hampden-Sydney College in Virginia, looked up one of the more 
-      obscure Latin words, consectetur, from a Lorem Ipsum passage, and 
-      going through the cites of the word in classical literature, 
-      discovered the undoubtable source. Lorem Ipsum comes from sections 
-      1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The 
-      Extremes of Good and Evil) by Cicero, written in 45 BC. This book 
-      is a treatise on the theory of ethics, very popular during the 
-      Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor 
-      sit amet..", comes from a line in section 1.10.32.
