+# Folding@home Binding
+
+Binding for the [Folding@home](https://folding.stanford.edu/) distributed computing
+software.
+
+This binding can control multiple Folding@home clients and slots, using the TCP
+interface.
+Clients are modeled as bridges, and support adding any number of slots
+(though, usually CPU and GPU).
+The binding provides control over Run / Pause and Finish.
+It polls for the status of the client, updates the run / pause state, and
+provides a basic description of the slot.
+
+The clients must be added manually in the Paper UI, but the slots for that
+client will then appear using auto-discovery.
+
+## Requirements (network access to F@H)
+
+The Folding@home TCP interface is enabled only on localhost by default, without
+a password.
+In order to allow control of Folding on other machines than the one
+running openHAB, it is necessary to configure the Folding client to accept commands
+from a non-localhost address.
+Here is how to do it in the FAHControl application:
+
+- Open FAHControl on the client to be added
+- Click on Configure, then the Remote Access tab
+- Enter a password twice (invent one)
+- Locate the Allow box under IP Address Restrictions
+- Append a space and the IP address of the machine running openHAB to the text in that box, so it reads something like `127.0.0.1 192.168.1.2`
+
+You should now have access to the client, configure it using the password and
+IP address in the manual thing configuration interface.
