+Netdata Functions feature allows you to execute on-demand a pre-defined routine on a node where a Netdata Agent is running. These routines are exposed by a given collector. 
+These routines can be used to retrieve additional information to help you troubleshoot or to trigger some action to happen on the node itself.
+
+
+### Prerequisites
+
+The following is required to be able to run Functions from Netdata Cloud.
+* At least one of the nodes claimed to your Space should be on a Netdata agent version higher than `v1.37.1`
+* Ensure that the node has the collector that exposes the function you want enabled ([see current available functions](https://github.com/netdata/netdata/blob/master/docs/cloud/netdata-functions.md#what-functions-are-currently-available))
+
+### Execute a function (from functions view)
+
+1. From the right-hand bar select the **Function** you want to run
+2. Still on the right-hand bar select the **Node** where you want to run it
+3. Results will be displayed in the central area for you to interact with
+4. Additional filtering capabilities, depending on the function, should be available on right-hand bar
+
+### Execute a function (from Nodes view)
+
+1. Click on the functions icon for a node that has this active
+2. You are directed to the **Functions** tab
+3. Follow the above instructions from step 3.
+
+> ⚠️ If you get an error saying that your node can't execute Functions please check the [prerequisites](#prerequisites).
