 ## Usage
 
-### Quickstart
+There are two ways to launch castor proxy:
 
-This command will start one Tor instance and HAProxy:
+- you can either use the castor script: [Castor script](#castor-script)
+
+- or use dirrectly docker commands: [Docker compose](#docker)
+
+### Castor script
+
+The script [`castor.sh`](castor.sh) can be used to start the castor proxy.
+
+#### Quickstart
+
+Start a SOCKS5 proxy on port 8080:
+
+```bash
+bash castor.sh start
+```
+
+Stop the proxy:
+
+```bash
+bash castor.sh stop
+```
+
+#### Usage
+
+```bash
+Usage: castor.sh [OPTIONS] COMMAND
+
+COMMANDS
+    start
+        starts castor
+    stop
+        stop castor
+
+OPTIONS
+    -h
+        Display usage statement
+    -p=int
+        Port to run the proxy (default=8080)
+    -m=socks|http
+        Proxy mode, either SOCKS5 or HTTP CONNECT proxy (default=socks)
+    -t=int
+        Number of Tor instances to run (default=5)
+```
+
+#### Simplify script usage
+
+##### Set an alias
+
+To simplify the use of this script and simply call it with `castor`, you can set an alias such as (assuming you are in castor directory):
+
+```bash
+alias castor='bash $(pwd)/castor.sh'
+```
+
+This alias should be written in the `~/.bashrc` file to make it permanent:
+
+```bash
+echo "alias castor='bash $(pwd)/castor.sh'" >> ~/.bashrc
+```
+
+##### Add autocompletion
+
+Once you setted an alias for the castor script, you can also add autocompletion for castor commands:
+
+```bash
+complete -W "start stop" castor
+```
+
+Once again to make the autocompletion permanent, you should add it in the `~/.bashrc` file:
+
+```bash
+echo "complete -W 'start stop' castor" >> ~/.bashrc
+```
+
+##### Simplified script usage
+
+After setting an alias and autocompletion, the script can be used from anywhere simply as following:
+
+```bash
+castor [OPTIONS] COMMAND
+```
+
+For instance to start the proxy on port 1234 with 15 Tor instances:
+
+```bash
+castor -p 1234 -t 15 start
+```
+
+### Docker
+
+The [castor script](castor.sh) simply calls docker-compose commands, so you can use docker-compose directly.
+
+#### Quickstart
+
+This command will start 5 Tor instance and HAProxy:
 
 ```bash
 docker-compose up
 ```
 
-By default the proxy will be a SOCKS5 proxy running on port **8080**.

+For instance to start 10 Tor instances:
 
 ```bash

+docker-compose up --scale tor=10
 ```
 
 By default, 5 tor instances are started. This also can be tunned in [`docker-compose.yml`](docker-compose.yml) file by editing the `scale` parameter of tor service.
