+.. ===================
+.. EvseSlac
+.. ===================
+
+This is an implementation of the ISO 15118-3 EVSE side SLAC protocol.
+The general flow of operation will be like this:
+
+- start of operation begins with a control pilot transition from state
+  A, E or F to Bx, Cx or Dx. This is indicated by the EvseManager by calling
+  the commands enter_bcd/leave_bcd.
+- Once started, it waits for a CM_SLAC_PARM_REQ from the EV side to start the SLAC session.
+- In case of success, SLAC finishes with a CM_SLAC_MATCH_RES, which sends a new NMK to the EV side.
+  The EV then joins the logical network and the two modems are paired. A dlink_ready(true) is published
+  to signal to the EvseManager that the low level PLC link is ready for communication.
+
+If not run as root user, this modules requires the capability CAP_NET_RAW.
+
+Todo
+====
+
+- make use of the enable flag in the reset command or drop it, if not needed
+- handle CM_VALIDATE.REQ message
+- implement PLC chip resetting after unplug or failed SLAC sessions (especially for QCA chips)
