+## Using the Install Script
+
+The simplest way is our install script, which you can fetch and
+execute as follows:
+
+```bash
+$ \curl -L https://github.com/STAMP-project/camp/raw/master/install.sh \
+  | sudo bash -s -- --python-library /usr/lib/python2.7
+```
+
+This script installs both the Z3 solver and CAMP. It accepts the
+following arguuments:
+
+```console
+Usage: sh install.sh [options...]
+Options:
+  -c, --camp-version STRING    Select a specific version of CAMP from Github.
+                               Can be a branch name (e.g., 'master'), a tag, or
+                               a commit hash. Default is 'master'.
+  -l, --z3-platform STRING     Install Z3 for a specific version of linux. 
+                               Default is 'x64-debian-8.10'.
+  -o, --only-z3                Does not install CAMP, but only the Z3 solver.
+                               Default is 'false'.
+  -p, --python-library DIR     Set the installation directory for the Z3 Python
+                               bindings. Default is '/usr/lib/python2.7'.
+  -z, --z3-version STRING      Set the version of the Z3 solver to install. 
+                               Default is 4.7.1.
+```
+
+Here, we specified where the Z3 Python bindings must be installed.
+
+Note the `--camp-version`, which let you install a specific version of
+CAMP. Here, we installed the development version, directly from the
+`master` branch.
+
+Once it completed, you can check that CAMP is running as follows:
+
+```console
+$ camp --help
+usage: CAMP [-h] {generate,realize,execute} ...
+
+Amplify your configuration tests!
+
+positional arguments:
+  {generate,realize,execute}
+    generate            Generate new test configurations
+    realize             Realize the variables in the test configurations
+    execute             Execute the test configurations generated
+
+optional arguments:
+  -h, --help            show this help message and exit

 ## Installing using Docker

+Another solution is to use [docker](https://www.docker.com/) to
 run CAMP and all its dependencies in one container, using the
 following command:
 
 ```bash

+$ docker run -it -v $(pwd):/camp/workspace fchauvel/camp:latest camp generate -d workspace

 This command will fetch the CAMP Docker image named

+`fchauvel/camp:latest` from [Docker
 Hub](https://hub.docker.com/r/fchauvel/camp/) and run it with your
 working directory ($pwd) mounted in the container at `/workspace`.
