-Installation for Users
-----------------------
-	$ git clone https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/PhoenixBinaryAnalyzer.git
+# Installation for Users
+
+```sh
+	$ git clone https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/PhoenixBinaryAnalyzer.git
 	$ cd PhoenixBinaryAnalyzer
 	$ ./install.sh
+```
+
+Then **PhoenixBinaryAnalyzer** is installed in your $HOME/usr.
+
+
+If you prefer a customized install path you can do :
+
+```sh
+	$ git clone https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/PhoenixBinaryAnalyzer.git
+	$ cd PhoenixBinaryAnalyzer
+	$ ./install.sh /your/install/path
+```
+
+If you prefer a customized install path with custom compilation you can do :
+
+```sh
+	$ git clone https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/PhoenixBinaryAnalyzer.git
+	$ cd PhoenixBinaryAnalyzer
+	$ mkdir -p build
+	$ cd build
+	$ cmake .. -DCMAKE_INSTALL_PREFIX=/your/install/Path
+	$ make -j `nproc`
+	$ make install -j `nproc`
+```
+
+The **nproc** gives the number of cores of the computer. If you want a build on one core you can just type :
+
+```sh
+	$ make
+	$ make install
+```
+
+
+# Update PhoenixBinaryAnalyzer
+
+If you want to update the software :
+
+```sh
+	$ git clone https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/PhoenixBinaryAnalyzer.git
+	$ cd PhoenixBinaryAnalyzer
+	$ ./update.sh
+```
+
+If you want to update the software with a custom install path :
+
+```sh
+	$ git clone https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS/PhoenixBinaryAnalyzer.git
+	$ cd PhoenixBinaryAnalyzer
+	$ ./update.sh /your/install/path
