 # Empty solution example for the S23DR competition
 
-This repo provides a minimalistic example of a valid, but empty submission to S23DR competition.
-We recommend to take a look at the [another example](https://huggingface.co/usm3d/handcrafted_baseline_submission),
-which implement some primitive algorithm and provides useful I/O and visualization functions.
-
-This one, though, containt the minimal code, which succeeds at reading the dataset and producing a solution, which consists of two vertices at the origin and edge of zero length connecting them.
+## Prerequisites
+*You must install hoho tools before running this script*
+```bash
+pip install git+http://hf.co/usm3d/tools.git
+```
 
+This repo provides a minimalistic example of a valid, but empty submission to S23DR competition.
+We recommend you also take a look at [this example](https://huggingface.co/usm3d/handcrafted_baseline_submission),
+which implements some primitive algorithms and provides useful I/O and visualization functions.
 
-The repo consistst of the following parts:
-
-- `script.py` - the main file, which is run by the competition space. It should produce `submission.parquet` as the result of the run.
-- `hoho.py` - the file for parsing the dataset at the inference time. Do NOT change it.
+The goal of this example is to show minimal code which succeeds at reading the dataset and producing a 
+solution (in this case two vertices at the origin connected by an edge of zero length).
 
+`script.py` is the main file. It is run by the competition space. It should produce `submission.parquet` as the result of the run.
