+# Useful Scripts
+
+In this section we will add scripts that might come handy. For instance, a script to upgrade some of the
+software you can find in the VM.
+
+
+### Installing all the p4-tools that come with the VM
+
+If you just want to install all the software required to start developing
+P4 you can use the [install-p4-tools.sh](../vm/bin/install-p4-tools.sh) script.
+
+You can change the two following variables to enable/disable debugging or the
+required software for the P4runtime.
+
+```bash
+DEBUG_FLAGS=true
+ENABLE_P4_RUNTIME=true
+```
+
+### Updating BMV2
+
+We provide a very useful script that allows you to easily update `bmv2` to the latest version,
+to a different commit, enable/disable debugging, multiqueuing and more. If you built the `vm`
+using vagrant or use the provided VM this script will be already installed in `/bin/` and you
+directly used it.
+
+```bash
+update-bmv2 -h
+
+update-bmv2 [OPTION]... [FILE]...
+
+Update bmv2/PI script options.
+
+ Options:
+  --enable-multi-queue: Enables simple_switch multiple queues per port
+  --update-code:        Before building cleans and pulls code from master or <use-commit>
+  --bmv2-commit:        Specific commit we want to checkout before building the bmv2
+  --pi-commit:          Specific commit we want to checkout before building PI
+  --enable-debugging:   Compiles the switch with debugging options
+  --enable-p4runtime:   Compiles the simple_switch_grpc
+  ```
+
+
+You can find the script [here](../vm/bin/update-bmv2.sh).
+
+### Updating P4C
+
+We also provide a similar script to update `p4c`, the P4 code compiler.
+
+```bash
+update-p4c -h
+
+update-p4c [OPTION]... [FILE]...
+
+Update p4c script options.
+
+ Options:
+  --update-code          Username for script
+  --p4c-commit:          Specific commit we want to checkout before building the bmv2
+  --enable-debugging:    Compiles the switch with debugging options
+  --copy-p4include:      Copies a custom p4include to the global path
+  --only-copy-p4include: Does not compile p4c
+```
+
+You can find the script [here](../vm/bin/update-p4c.sh).
