* Download a .iso image of a Linux distribution
* Create a VM configuration file; for example `ubuntu.conf`

+## Tuning CPU cores, RAM & disks
+
+By default, Quickemu will calculate the number of CPUs cores and RAM to allocate
+to a VM based on the specifications of your host computer. You can override this
+default behaviour and tune the VM configuration to your liking.
+
+Add additional lines to your virtual machine configuration:
+
+ * `cpu_cores="4"` - Specify the number of CPU cores allocated to the VM
+ * `ram="4G"` - Specify the amount of RAM to allocate to the VM
+ * `disk="16G"` - Specify the size of the virtual disk allocated to the VM
+
+## Network port forwarding
+
+Add an additional line to your virtual machine configuration. For example:
+
+ * `port_forwards=("8123:8123" "8888:80")`
+
+In the example above:
+
+ * Port 8123 on the host is forwarded to port 8123 on the guest.
+ * Port 8888 on the host is forwarded to port 80 on the guest.
