+# Trivial Tracer
+
+To compile the project run `make compile`.
+To start the tracers run `make run`.
+
+Run options can be passed through environment variables, the are:
+- `CORNEL=true` : Run the cornel room example instead of the spheres room.
+- `PATH_TRACE=true` : Uses a path tracer instead of a ray tracer.
+- `THREADS=true` : Enables multi-threading. 
+
+#### Examples:
+```shell
+$ make run
+$ CORNEL=true make run
+$ PATH_TRACE=true make run
+$ CORNEL=true PATH_TRACE=true THREADS=true make run
+```
