+# Traceroute Internet Mapper - TIM
+
+## Development
+
+```sh
+# Install all dependencies. `pipenv` was used previously:
+pipenv --python 3.11
+pipenv install
+pipenv shell
+
+# Start dev server
+fastapi dev app/main.py
+
+# Start posting data to the tracing endpoint:
+traceroute git.rauhala.info -q1 | http POST localhost:8000/trace/MYHOSTNAME
+```
+
+## URLs of interest
+
+- http://localhost:8000/
+  - API Index, nothing to see.
+
+- http://localhost:8000/docs/
+  - Autogenerated API docs, mildy interesting
