 * `Conductor Signal Changer` : Like a diode which can be activated by sending a signal on its pin "F", and deactivated by sending a signal on its pin "O".
 * `Dual Delayer` : If it receives a mesecons signal, port 1 turns on immediatly and port 2 turns on 0.4 seconds later. At the end of the signal, port 2 turns off immediatly and port 1 turns off 0.4 secondes later. For example, this is useful for double extenders.
 * `Entity Detector` : You can use it to detect an entity. You can choose the entity to detect by right-click (use itemstring, for example "mobs:rat". To detect a dropped item, write "__builtin:item". To detect a specific dropped item, write its itemstring (for example "default:cobble")).
-* `Igniter` : This node is a lighter that ignites ajacent flammable nodes (including TNT).
+* `Igniter` : This node is a lighter that ignites its adjacent flammable nodes (including TNT).
 * `Injector Controller` : This node is useful to activate/deactivate a pipeworks filter injector : it sends a blinky signal.
 * `Jammer` : If turned on, this node stops mesecons in a radius of 10 nodes.
+* `LuaBlock`: This block allows its owner to execute any Lua code in the global environment when turned on. Using it requires the server privilege.
 * `Luacontroller Template Tool` : This tool is very useful to manipulate templates with luacontrollers. Just click with it on a luacontroller, then you'll see a formspec.
 * `Player Killer` : This block kills the nearest player (with a maximal distance of 8 blocks by default) (if this player isn't its owner) when it receives a mesecons signal.
 * `Sayer` : This node sends a message to every players inside a radius of 8 nodes.
 * `Signal Changer` : If it receives a signal on its pin "F", it turns on. If it receives a signal on its pin "O", it turns off. Note : an inverted signal is sended at the other end of the arrow.
 * `Switch Torch` : It connects just like Mesecons Torch. If it receives a signal, it turns on, and if it receives a second signal, it turns off.
-* `Teleporter` : If you place one teleporter, if it receives a mesecons, it teleports the nearest player on itself. If you place two teleporters on the same axis, if one receives a mesecons signal, it teleports the nearest player on the second (with a maximal distance of 50 nodes by default). The player teleporter must be inside a radius of 25 nodes.
-* `Temporary Gate` : If it receives a mesecons signal, whatever its duration, a mesecons signal is send with a fixed duration. You can change it by right-click (in seconds) (you can write for example 0.2 to send a pulse, or 20 to send long signals).
+* `Teleporter` : If you place one teleporter, it teleports the nearest player on itself when it receives a mesecons signal. If you place two teleporters on the same axis, when one receives a mesecons signal, it teleports the nearest player on the second (with a maximal distance of 50 nodes by default). The player teleporter must be inside a radius of 25 nodes.
+* `Time Gate` : If it receives a mesecons signal, whatever its duration, a mesecons signal is send with a fixed duration. You can change it in the formspec by right-clicking on the gate.
 * `Wireless` : Place 2 (or more) wireless somewhere. Change their channel by right-click. If you send a signal to a wireless, every wireless wich have the same channel will send the signal. Compatible with digiline mod.
 * `Wireless Jammer` : If it receives a mesecons signal, it deactivates all wireless (receptors) in a radius of 15 nodes.

+## Settings
+
+You can set the settings by using the Minetest GUI ("Settings" tab -> Advanced settings -> Mods -> MoreMesecons).
+
+## The Sayer and the Speech Dispatcher
+
+[Speech Dispatcher project](http://freecode.com/projects/speech-dispatcher)
+
+The Sayer item is able to speak on your speakers using the speech dispatcher, under these conditions:
+1. The moremesecons_sayer mod is present in your trusted_mods setting
+2. You are playing in singleplayer.
+3. You are using a POSIX-compliant system and a sh-compatible shell (such as bash, dash, zsh...). Microsoft Windows is NOT POSIX-compliant.
+4. The speech dispatcher is installed on your system.
+
+The mod is able to detect issues 1, 2, and 4 by itself and then disable the speech dispatcher ; however, if you are using a non-POSIX-compliant system, the mod will crash on startup and you will need to disable the speech dispatcher manually (Settings tab -> Advanced settings -> Mods -> MoreMesecons -> Sayer -> Use the Speech Dispatcher).
