+## Quick start
+
+```bash
+curl fablo.io/install.sh | bash
+./fablo init node rest
+./fablo up
+```
+
+This will create a local Hyperledger Fabric network with a sample Node.js chaincode (using the `node` parameter) and a REST API client (using the `rest` parameter).
+After a few minutes, the entire network will be set up and running.
+
+You can check the running nodes using `docker ps` or `docker stats`. You can also query the network via the command line (`fablo chaincode invoke` or `fablo chaincode query`), use the REST API client (see [Fablo REST](https://github.com/fablo-io/fablo-rest)), or view the network topology in the `fablo-target/network-topology.mmd` Mermaid diagram.

 ## Installation
 
 Fablo is distributed as a single shell script that uses a Docker image to generate the network configuration.
-You can keep the script in the root directory of your project or install it globally on your system.
-
-To get a copy of Fablo for a single project, run this command in your project root:
+To install it locally in your project directory:
 
 ```bash
-curl -Lf https://github.com/hyperledger-labs/fablo/releases/download/2.4.3/fablo.sh -o ./fablo && chmod +x ./fablo
+curl fablo.io/install.sh | bash
+# OR
+curl fablo.io/fablo.sh > fablo && chmod +x fablo
 ```
 
-To install it globally, run:
+To install it globally on your system:
 
 ```bash
-sudo curl -Lf https://github.com/hyperledger-labs/fablo/releases/download/2.4.3/fablo.sh -o /usr/local/bin/fablo && sudo chmod +x /usr/local/bin/fablo
+sudo curl fablo.io/fablo.sh -o /usr/local/bin/fablo && sudo chmod +x /usr/local/bin/fablo
 ```
 
-## Getting started
+To install a given version use:
+
+```bash
+curl https://github.com/hyperledger-labs/fablo/releases/download/<version>/fablo.sh
+```
 
-To create a local Hyperledger Fabric network with Node.js chaincode and REST API client, install Fablo and run:
+To change version of current installation:
 
 ```bash
-fablo init node rest
-fablo up
+fablo use <version>
 ```
 
-Note: For local setup use `./fablo` instead of `fablo`.
+Note: If you install Fablo as a local script, you call it as `./fablo <command>`.
+If you install it globally, you call `fablo <command>`.
+For the simplicity we will refer to it as `fablo`.
 
-After a few minutes, the entire network will be set up and running.
-You can check the running nodes using `docker ps` or `docker stats`, and query the network via command line (`fablo chaincode invoke|query`) or REST API client (via [Fablo REST](https://github.com/fablo-io/fablo-rest)).
