+# Vagrant
+
+Please install [Vagrant](https://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/).
+After that you can run the Vagrant environment with just one command:
+
+```bash
+vagrant up
+```
+
+After successfull installation you can ssh to the virtual machine with:
+
+```bash
+vagrant ssh
+```
+
+## Collector
+
+To install or upgrade collector please type:
+
+```bash
+/sumologic/vagrant/Makefile upgrade
+```
+
+This command will prepare environment (namespaces, receiver-mock, etc.)
+and after that it will install/upgrade collector in the vagrant environment.
+
+To remove collector please use:
+
+```bash
+/sumologic/vagrant/Makefile clean
+```
+
+List of other useful commands in the Makefile:
+  - `expose-prometheus` - exposes prometheus on port 9090 of virtual machine
+  - `expose-grafana` - exposes grafana on port 8080 of virtual machine
+  - `apply-avalanche` - run one pod deployment of avalanche (metrics generator)
