 A neuron is a module that will perform some actions attached to an order. You can use it in your synapses. See the [complete neuron documentation](neurons.md) for more information.

+
+## Synapses example
+
+Simple call to a server. The default method is GET
+```
+  - name: "test-get-url"
+    signals:
+      - order: "test-get-url"
+    neurons:
+      - uri:
+          url: "http://host.domain/get/1"             
+```
+
+A simple call with authentication
+```
+- name: "test-get-url-with-auth"
+    signals:
+      - order: "test-get-url-with-auth"
+    neurons:
+      - uri:
+          url: "http://host.domain/get/1"        
+          user: "admin"
+          password: "secret"
+```
+
+A simple post with data inside the url 
+```
+- name: "test-post-url-with-auth"
+    signals:
+      - order: "test-post-url-with-data"
+    neurons:
+      - uri:
+          url: "http://host.domain/login?email=user@host.domain&password=foobar123" 
+          method: POST          
+```
+
+A post with json data. Note that we need to escape quotes from the payload.
+```
+- name: "test-post-url"
+    signals:
+      - order: "test-post-url"
+    neurons:
+      - uri:
+          url: "http://host.domain/posts"
+          method: POST
+          headers:            
+            Content-Type: 'application/json'      
+          data: "{\"id\": 1,\"title\": \"foo\", \"body\": \"bar\", \"userId\": 1}"         
+```
+
+A post with json data imported from a file and a custom header.
+```
+- name: "test-post-url"
+    signals:
+      - order: "test-post-url"
+    neurons:
+      - uri:
+          url: "http://host.domain/posts"
+          method: POST
+          headers:            
+            Content-Type: 'application/json'
+            user-agent: 'my-app/0.0.1'
+          data_from_file: "/path/to/my/payload.json"        
+```
+
+And the `payload.json` would be (note that we don't need to escape any character):
+```
+{"title": "foo", "body": "bar", "userId": 1}
+```
+
+A simple call to a deletion. Here we also ask Kalliope to tell use if request was a success through a template, depending on the returned status code.
+```
+  - name: "test-delete-url"
+    signals:
+      - order: "test-delete-url"
+    neurons:
+      - uri:
+          url: "http://host.domain/posts/1"
+          method: DELETE          
+          say_template:
+            - "{% if status_code==201 %}delete complete{% else %}fail to delete{% endif %}"
+```
+
+Call to an URL to get a resource and make kalliope speaking out loud a value of returned content.
+Here, we ask the server to return us the user with ID number 42. We know that the server will return a dict like the following
+```
+{
+  "id": 42,
+  "name": "Leanne Graham",
+  "username": "Bret",
+  "email": "Sincere@april.biz",
+  "phone": "1-770-736-8031 x56442",
+  "website": "hildegard.org",
+  "company": {
+    "name": "Romaguera-Crona",
+    "catchPhrase": "Multi-layered client-server neural-net",
+    "bs": "harness real-time e-markets"
+  }
+}

+
+Here is the synapse we would use to make Kalliope speak out loud the name of the user and the name of his company
+```
+  - name: "test-get-url-with-template"
+    signals:
+      - order: "test-get-url-with-template"
+    neurons:
+      - uri:
+          url: "http://host.domain/users/42"                
+          say_template:
+            - "The user name is {{ content.name }} and his company's name is {{ content.company.name }}"
+```
+
+
+## Templates example 
+
+The following template will make kalliope read the content of the received json variable "title" from the remote server.
+```
+The title is {{ content.title }}
+```
+
+The following template will make Kalliope say if the request has been made with success or not depending on the returned status code.
+```
+{% if status_code==200 %}request complete{% else %}request failled{% endif %}
+```
+
+## Notes
+> When the parameter `data` is used, you need to escape character that could be interpreted by the YAML syntax.
