+# conllu (exporter)
+
+This module exports a graph in CoNLL-U format.
+
+## Configuration
+
+###  doc
+
+This key is used to determine nodes that whose part-of subgraph constitutes a document, i. e. the entire input for a file.
+Default is `annis::doc`, or `{ ns = "annis", name = "doc" }`.
+
+Example:
+```toml
+[export.config]
+doc = "annis::doc"
+```
+
+###  groupby
+
+This optional annotation key is used to identify annotation spans, that constitute a sentence. Default is no export of sentence blocks.
+Default is `annis::doc`, or `{ ns = "annis", name = "doc" }`.
+
+Example:
+```toml
+[export.config]
+groupby = "norm::sentence"
+```
+
+###  ordering
+
+The nodes connected by this annotation component are used as nodes defining a line in a CoNLL-U file. Usually you want to use an ordering.
+Default is `{ ctype = "Ordering", layer = "annis", name = "" }`.
+
+Example:
+```toml
+[export.config]
+ordering = { ctype = "Ordering", layer = "annis", name = "norm" }
+```
+
+###  form
+
+This annotation key is used to write the form column.
+Default is `{ ns = "annis", name = "tok" }`.
+
+Example:
+```toml
+[export.config]
+form = { ns = "norm", name = "norm" }
+```
+
+###  lemma
+
+This annotation key is used to write the lemma column.
+Default is `{ ns = "", name = "tok" }`.
+
+Example:
+```toml
+[export.config]
+lemma = { ns = "norm", name = "lemma" }
+```
+
+###  upos
+
+This annotation key is used to write the upos column.
+Default is `{ ns = "", name = "upos" }`.
+
+Example:
+```toml
+[export.config]
+upos = { ns = "norm", name = "pos" }
+```
+
+###  xpos
+
+This annotation key is used to write the xpos column.
+Default is `{ ns = "", name = "xpos" }`.
+
+Example:
+```toml
+[export.config]
+upos = { ns = "norm", name = "pos_spec" }
+```
+
+###  features
+
+This list of annotation keys will be represented in the feature column.
+Default is the empty list.
+
+Example:
+```toml
+[export.config]
+features = ["Animacy", "Tense", "VerbClass"]
+```
+
+###  dependency_component
+
+The nodes connected by this annotation component are used to export dependencies.
+Default is none, so nothing will be exported.
+
+Example:
+```toml
+[export.config]
+dependency_component = { ctype = "Pointing", layer = "", name = "dependencies" }
+```
+
+###  dependency_anno
+
+This annotation key is used to write the dependency relation, which will be looked for on the dependency edges.
+Default is none, so nothing will be exported.
+
+Example:
+```toml
+[export.config]
+dependency_anno = { ns = "", name = "deprel" }
+```
+
+###  enhanced_components
+
+The listed components will be used to export enhanced dependencies. More than
+one component can be listed.
+Default is the empty list, so nothing will be exported.
+
+Example:
+```toml
+[export.config]
+enhanced_components = [{ ctype = "Pointing", layer = "", name = "dependencies" }]
+```
+
+###  enhanced_annos
+
+This list of annotation keys defines the annotation keys, that correspond to the
+edge labels in the component listed in `enhanced_components`. The i-th element of
+one list belongs to the i-th element in the other list. Default is the empty list.
+
+Example:
+```toml
+[export.config]
+enhanced_annos = ["func"]
+```
+
+###  misc
+
+This list of annotation keys will be represented in the misc column.
+Default is the empty list.
+
+Example:
+```toml
+[export.config]
+misc = ["NoSpaceAfter", "Referent"]
+```
