 # Testnet injector
 
-A simple HTTP API to inject transactions or behaviors in an EcoMobiCoin test network.
+A CLI tool to inject transactions or behaviors in an EcoMobiCoin blockchain.
 
-## Features
+## Components
 
 This project heavily use the forked and adapted [ethers-rs](https://gitlab.limos.fr/ecomobicoin/ethers-rs).
 
-# Simulate tx & bx
+### ETL
+
+- Extract CSV file e.g. `dataset-extract.csv` to `MobilityRecord`
+- Transform it with simulation params (relative time from earliest entry and behavior attributes)
+- Load in local DB
+
+### Sending Queue
+
+## Usage
+
+### Simulate tx & bx
 
 To simulate Behaviors from a CSV Mobility dataset, run `cargo run simulate-bx-from-csv < data/dataset-extract.csv`
 
+Options:
+
+- dataset e.g. CSV file
+- `total_simulation_duration` in seconds (or minutes ?)
+
+### Send
+
+Send tx or bx
+
+Options:
+
+- `time_period` in seconds
+- `n` number e.g. 10
+- `tx | bx | txbx` sending tx, bx or both
+
 ## Env vars
 
 Copy the env example file to `.env` with the following command: `cp .env.example .env`
