+#### The neurotransmitter case
+
+In case of leveraging the [neurotransmitter neuron](https://github.com/kalliope-project/kalliope/tree/master/kalliope/neurons/neurotransmitter), Kalliope expects back and forth answers.
+Fortunately, the API provides a way to continue interaction with Kalliope and still use neurotransmitter neurons while doing API calls.
+
+When you start a synapse via its name or an order (like shown above), the answer of the API call will tell you in the response that kalliope is waiting for a response via the "status" return. 
+
+Status can either by ```complete``` (nothing else to do) or ```waiting_for_answer```, in which case Kalliope is waiting for your response :).
+
+In this case, you can launch another order containing your response.
+
+Let's take as an example the simple [neurotransmitter brain of the EN starter kit](https://github.com/kalliope-project/kalliope_starter_en/blob/master/brains/neurotransmitter.yml):
+
+First step is to fire the "ask me a question order":
+
+```bash
+curl -i --user admin:secret -H "Content-Type: application/json" -X POST -d '{"order":"ask me a question"}' http://localhost:5000/synapses/start/order
+```
+
+The response should be as follow:
+
+```JSON
+{
+  "matched_synapses": [
+    {
+      "matched_order": "ask me a question",
+      "neuron_module_list": [
+        {
+          "generated_message": "do you like french fries?",
+          "neuron_name": "Say"
+        }
+      ],
+      "synapse_name": "synapse1"
+    }
+  ],
+  "status": "waiting_for_answer",
+  "user_order": "ask me a question"
+}
+```
+
+The ```"status": "waiting_for_answer"``` indicates that it waits for a response, so let's send it:
+
+```bash
+ --user admin:secret -H "Content-Type: application/json" -X POST -d '{"order":"not at all"}' http://localhost:5000/synapses/start/order
+```
+
+```JSON
+{
+  "matched_synapses": [
+    {
+      "matched_order": "ask me a question",
+      "neuron_module_list": [
+        {
+          "generated_message": "do you like french fries?",
+          "neuron_name": "Say"
+        },
+        {
+          "generated_message": null,
+          "neuron_name": "Neurotransmitter"
+        }
+      ],
+      "synapse_name": "synapse1"
+    },
+    {
+      "matched_order": "not at all",
+      "neuron_module_list": [
+        {
+          "generated_message": "You don't like french fries.",
+          "neuron_name": "Say"
+        }
+      ],
+      "synapse_name": "synapse3"
+    }
+  ],
+  "status": "complete",
+  "user_order": null
+}
+
+```
+
+And now the status is complete. This works also when you have nested neurotransmitter neurons, you just need to keep monitoring the status from the API answer.
+

-### random_wake_up_answers
-When Kalliope detects your trigger/hotword/magic word, it lets you know that it's operational and now waiting for order. It's done by answering randomly
-one of the sentences provided in the variable random_wake_up_answers.
+Hooking allow to bind actions to events based on the lifecycle of Kalliope. 
+For example, it's useful to know when Kalliope has detected the hotword from the trigger engine and make her spell out loud that she's ready to listen your order.
 
-This variable must contain a list of strings as shown bellow
+To use a hook, attach the name of the hook to a synapse (or list of synapse) which exists in your brain.
+
+Syntax:
 ```yml
-random_wake_up_answers:
-  - "You sentence"
-  - "Another sentence"

-## On ready notification
-This section is used to notify the user when Kalliope is waiting for a trigger detection by playing a sound or speak a sentence out loud
+Example: You want to know that your order has not been found
 
-### play_on_ready_notification
-This parameter define if you play the on ready notification:
- - `always`: every time Kalliope is ready to be awaken
- - `never`: never play a sound or sentences when kalliope is ready
- - `once`: at the first start of Kalliope
-
-E.g:
+**settings.yml**
 ```yml
-play_on_ready_notification: always
+hooks:
+  on_order_not_found: "order-not-found-synapse"
 ```
-### on_ready_answers
-The on ready notification can be a sentence. Place here a sentence or a list of sentence. If you set a list, one sentence will be picked up randomly
 
-E.g:
+**brain.yml**
 ```yml
-on_ready_answers:
-  - "I'm ready"
-  - "Waiting for order"
+- name: "order-not-found-synapse"
+    signals: []
+    neurons:
+      - say:
+          message:
+            - "I haven't understood"
+            - "I don't know this order"
+            - "Please renew your order"
+            - "Would you please reword your order"
+            - "Can ou please reformulate your order"
+            - "I don't recognize that order"
 ```
 
-### on_ready_sounds
-You can play a sound instead of a sentence.
-Remove the `on_ready_answers` parameters by commenting it out and use this one instead.
-Place here the path of the sound file. Files must be .wav or .mp3 format.
+Example: You are running Kalliope on a Rpi. You've made a script that turn on or off a led.
+You can call this script every time kalliope start or stop speaking
 
-E.g:
+**settings.yml**
 ```yml
-on_ready_sounds:
-  - "ding.wav"
-  - "dong.wav"
-  - "/my/personal/full/path/my_file.mp3"
+hooks:
+  on_start_speaking: "turn-on-led"
+  on_stop_speaking: "turn-off-led"
 ```
 
->**Note: ** If you want to use a on ready sound instead of a on ready you must comment out the `random_on_ready_answers` section.
-E.g: `# random_on_ready_answers:`
+**brain.yml**
+```yml
+- name: "turn-on-led"
+  signals: []   
+  neurons:
+    - script:
+        path: "/path/to/script.sh on" 
+        
+- name: "turn-off-led"
+  signals: []   
+  neurons:
+    - script:
+        path: "/path/to/script.sh off"  
+```
 
+>**Note:** You cannot use a neurotransmitter neuron inside a synapse called from a hook. 
+You cannot use the "say" neuron inside the "on_start_speaking" or "on_stop_speaking" or it will create an infinite loop

->**Note:** You must ALWAYS use resistors to connect LEDs up to the GPIO pins of the Raspberry Pi. 
-The Raspberry Pi can only supply a small current (about 60mA). T
-he LEDs will want to draw more, and if allowed to they will burn out the Raspberry Pi. 
-Therefore putting the resistors in the circuit will ensure that only this small current will flow and the Pi will not be damaged.

+# Debug
+
+## Synopsis
+
+Print a message in the console. This neuron can be used to check your [captured variable from an order](../../Docs/neurons.md#input-values) or check the content of variable placed 
+in [Kalliope memory](../../Docs/neurons.md#kalliope_memory-store-in-memory-a-variable-from-an-order-or-generated-from-a-neuron).
+
+## Installation
+
+CORE NEURON : No installation needed.  
+
+## Options
+
+| parameter | required | default | choices | comment                                  |
+|-----------|----------|---------|---------|------------------------------------------|
+| message   | YES      |         |         | Message to print in the console output   |
+
+## Return Values
+
+No returned values
+
+## Synapses example
+
+Simple example : 
+```yml
+- name: "debug"
+  signals:
+    - order: "print a debug"
+  neurons:
+    - debug:
+        message: "this is a debug line"     
+```
+
+Output example:
+```
+[Debug neuron, 2017-12-17 17:30:53] this is a debug line
+```
+
+Show the content of captured variables from the spoken order
+```yml
+- name: "debug"
+  signals:
+    - order: "tell me what I say {{ here }}"
+  neurons:
+    - debug:
+        message: "{{ here }}"     
+```
+
+Show the content of a variable placed in Kalliope memory
+```yml
+- name: "debug"
+  signals:
+    - order: "what time is it?"
+  neurons:
+    - systemdate:
+        say_template:
+          - "It' {{ hours }} hours and {{ minutes }} minutes"

+# Geolocalisation
+
+## Synopsis
+
+**Geolocation** is a way to launch a synapse when ENTERING a geolocated zone.
+
+As Kalliope does not manage its own geolocation, this signal has been designed in view to be implemented from external clients (smartphones, watches, embedded devices, etc).
+
+The syntax of a geolocation declaration in a synapse is the following.
+```yml
+signals:
+    - geolocation:
+          latitude: "46.204391"
+          longitude: "6.143158"
+          radius: "10000"
+```
+
+For example, if we want Kalliope to run the synapse when entering in Geneva
+```yml
+- geolocation:
+      latitude: "46.204391"
+      longitude: "6.143158"
+      radius: "1000"
+```
+
+## Options
+
+Parameters are keyword you can use to build your geolocation
+
+List of available parameter:
+
+| parameter   | required | default | choices                                                         | comment   |
+|-------------|----------|---------|-----------------------------------------------------------------|-----------|
+| latitude    | yes      |         | 46.204391                                                         | E.g: 2016 |
+| longitude   | yes      |         | 6.143158                                                    |           |
+| radius      | yes      |         | 1 (meters)                                               |           |
+
+## Synapses example
+
+### Web clock radio
+
+Let's make a complete example. 
+We want to Kalliope to :
+- welcome when coming back home
+- Play our favourite web radio
+
+The synapse in the brain would be:
+```yml
+  - name: "geolocation-welcome-radio"
+    signals:
+      - geolocation:
+            latitude: "46.204391"
+            longitude: "6.143158"
+            radius: "10"
+    neurons:
+      - say:
+          message:
+            - "Welcome Home!"
+      - shell: 
+          cmd: "mplayer http://192.99.17.12:6410/"
+          async: True
+```
+
+After setting up a geolocation signal, you must restart Kalliope
+```bash
+python kalliope.py start
+```
+
+If the syntax is NOT ok, Kalliope will raise an error and log a message:
+```
+[Geolocation] The signal is missing mandatory parameters, check documentation
+```
+
+### Note
+

+| matching-type | NO       | normal             | normal, strict, ordered-strict | Type of matching. See explanation bellow |
+
+**Matching-type:**
+- **normal**: Will match if all words are present in the spoken order.
+- **strict**: All word are present. No more word must be present in the spoken order.
+- **ordered-strict**: All word are present, no more word and all word are in the same order as defined in the signal.

 ## Values sent to the synapse
 
 None
 
 ## Synapses example
 
-### Simple order
+### Normal order
 
 Syntax:
 ```yml
 signals:
-    - order: "<sentence>"
+  - order: "<sentence>"
+
+signals:
+  - order:
+      text: "<sentence>"
+      matching-type: "normal"
 ```
 
 Example:
 ```yml
 signals:
-    - order: "please do this action"
+  - order: "please do this action"
+
+signals:
+  - order:
+      text: "please do this action"
+      matching-type: "normal"
 ```
 
+In this example, with a `normal` matching type, the synapse would be triggered if the user say:
+- please do this action
+- please do this action with more word
+- action this do please
+- action this do please with more word
+
+### Strict order
+
+Syntax:
+```yml
+signals:
+    - order:
+        text: "<sentence>"
+        matching-type: "strict"
+```
+
+Example:
+```yml
+signals:
+    - order:
+        text: "please do this action"
+        matching-type: "strict"
+```
+
+In this example, with a `strict` matching type, the synapse would be triggered if the user say:
+- please do this action
+- action this do please
+
+### Ordered strict order
+
+Syntax:
+```yml
+signals:
+    - order:
+        text: "<sentence>"
+        matching-type: "ordered-strict"
+```
+
+Example:
+```yml
+signals:
+    - order:
+        text: "please do this action"
+        matching-type: "ordered-strict"
+```
+
+In this example, with a `strict` matching type, the synapse would be triggered if the user say:
+- please do this action
+
+### Notes
+
 > **Important note:** SST engines can misunderstand what you say, or translate your sentence into text containing some spelling mistakes.
 For example, if you say "Kalliope please do this", the SST engine can return "caliope please do this". So, to be sure that your speaking order will be correctly caught and executed, we recommend you to test your STT engine by using the [Kalliope GUI](kalliope_cli.md) and check the returned text for the given order.
