+# Tuugen
+
+Tuugen takes a tuugen.yml and a grpc proto definition to generate common boiler plate logic. Some of the common boiler plate it generates is http routes, grpc service, data model structs and a main file with some default plumbing.
+
+Tuugen adds an interactor package which the http and grpc transport layers use for business logic.
+
+Feel free to pull the repo and play around with the example_project.
+
+## Using Tuugen.
+
+```
+go install github.com/cubixle/tuugen
+```
+
+And the run `tuugen` in the root dir of your project or wherever you have your tuugen and proto file.
+
+## Example tuugen file
+```yaml
+project: tuugen_test_project
+import_path: github.com/cubixle/tuugen/example_project
+proto_file: service.proto
+grpc_file: internal/pb/service/service_grpc.pb.go
+service_name: Service
+data_models:
+  - name: User
+    properties:
+      - name: id
+        type: varchar
+        autoinc: true
+      - name: team_id
+        type: varchar
+      - name: name
+        type: varchar
+      - name: email
