+# Gitea-tanslator
+The module can be used by importing `inputs.self.nixosModules.malobeo.gitea-translator`
+
+This module starts a python server that fetches the gitea pull request api and translates it to a file that hydra understands.   
+To use, just set the parameters of the gitea server, then send a GET request to either `http://${host}:${port}/` or `http://${host}:${port}/gitea-pulls-sorted.json`
+
+## Module config
+##### enable (default = false) - enables the module  
+##### baseurl (default = "git.dynamicdiscord.de") - Base URL of the Gitea instance   
+##### owner (default = "malobeo") - Repository owner   
+##### repo (default = "infrastructure") - Repository name   
+##### host (default = "127.0.0.1") - Address the server binds to   
+##### port (default = 27364) - Port the server listens on   
+
+## Hydra config
+If you change the default port or host, the file `.hydra/spec.json` has to be modified accordingly.
+With the module running on the hydra host, create a new hydra project, then:
+
+    - Set `Declarative spec file` to `.hydra/spec.json`
+    - Change declaritive input type to `Git checkout`
+    - Set your git repo location in the field below that
