 # textsender-auth
 A service that handles the authorization aspect of the textsender project.
+
+
+## Getting started
+Assumes that the postgresql database has already been created with privileges to
+create and drop databases. Copy the `.env.sample` file to `.env`. Within the `.env`
+file, update the database keys. The `SECRET_KEY` is used for token generation.
+
+
+### Building api
+```
+make build
+```
+
+
+### Resetting the database
+```
+./textsender-auth -reset-db
+```
+
+
+Generate API documentation
+```
+go install github.com/swaggo/swag/cmd/swag@latest
+go get -u github.com/swaggo/http-swagger/v2
+
+swag init --generalInfo main.go --dir ./cmd/api,./internal/handler --output docs/ --parseDependency --parseInternal
+```
+
+The API documentation can be viewed from `http://localhost:9080/swagger/index.html`.
