+# Notes
+
+Notes are a Signal K resource type that provide a means to capture and display additional information in a variety of formats. They are accessed via the Signal K API path `/signalk/v1/api/resources/notes`.
+
+Notes can contian both text and / or a link to additional text, images, etc.
+
+They can stand alone or be associated with: 
+- a geographic location by assigning a value to `position`
+- an area by assigning a value to `geohash` or `region` 
+- other notes by entering the same value in `group`  for each of the related notes.
+
+---
+
+### Note Properties:
+
+`title`: Text containing the title of the note.
+
+`description`: Text describing the object that the note is associated with.
+
+`mimeType`: MIME type of the note. If this property is `null` or `undefined` then the note is considered plain text.
+
+`url`: Link to additional note content. If this property is `null` or `undefined` then the `description` should be considred the content of the note. 
+
+`group`: Text representing the name of a collection that this note is part of. Notes with the same `group` value are considered part of the collection. If this property is `null` or `undefined` then the note is not part of any collection.
+
+`authors`: A list containing the details of the authors / contributors to the note content. Each author entry can contain one or more of the following: `name`, `email`, `url`.
+
+`geohash`: Geographic area to which the note is attached.
+
+`position`: Geographic position to which the note is attached. If defined in conjunction with `geohash`, it should be within the `geohash` area.
+
+`region`: The UUID of a `region` resource to which the Note is attached.
+
+`properties`: An object that is a placeholder for application / use case specific values.
+
+_Example: Define a `draft` property to indicate the note has not been finalised._
+```json
+{
+    "title": "Big Island",
+    "description": "Big Island Approach notes.....",    
+    "geohash": "rbejg",
+    "properties": {
+        "draft": true
+    }               
+}
+```
+
+### Example: Combining `region` and `group`
+
+Using a combination of `region` and `group` the following notes contain information about safe anchorages in the Great Barrier Reef _(defined in a `region` resource)_.
+
+```json
+{
+    "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc4123b" : {
+        "title": "Whitehaven Beach",
+        "description": "Whitehaven Beach is a pristinebeach on Whitsunday Island.....",    
+        "geohash": "rk3uv",
+        "group": "GBR Safe Anchorages",
+        "region": "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc8021e"              
+    },
+    "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc4123b" : {
+        "title": "Shute Harbour",
+        "description": "is a sheltered port for small vessels located approximately 10 km east of Airlie Beach.....",    
+        "geohash": "rk3u9",
+        "group": "GBR Safe Anchorages",
+        "region": "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc8021e"
+    }
+}
+```
+
+### Example: Combining `region`, `geohash` and `position`
+
+By using a combination of `region`, `geohash` and `position` notes can be assigned to specific geolocations within an area.
+```json
+{
+    "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc4123b" : {
+        "title": "Big Harbour etry",
+        "description": "...is a sheltered port .....",    
+        "region": "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc8021e",
+        "geohash": "rk3u9",
+        "position":{
+            "latitude": -20.2919444444,
+            "longitude": 148.785
+        }
+    },
+    "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc4123b" : {
+        "title": "Big Harbour Jetty",
+        "description": "...",    
+        "region": "urn:mrn:signalk:uuid:c0d79335-4e25-4245-8892-54e8ccc8021e",
+        "geohash": "rk3u9",
+        "position":{
+            "latitude": -20.2913,
+            "longitude": 148.779
+        }      
+    }
+}
+```

+
+## Working with Notes
+
+The retrieval, creation, updating or deletion of notes is done by making the appropriate request to the Signal K server. 
+
+See [Request/Response](request_response.md) for more details on request/response behaviour in Signal K.
+
+_Note: Resource requests do not require a `context`._
+
+---
+#### RETRIEVING NOTES
+To retrieve a list of notes from the server make a __GET__ request to the notes path.  _e.g. `/signalk/v1/api/resources/notes`_ 
+
+To retrieve an individual note make a __GET__ request to its path. 
+
+__via HTTP:__
+```
+GET `/signalk/v1/api/resources/notes/urn:mrn:signalk:uuid:36f9b6b5-959f-46a1-8a68-82159742aadd`_
+```
+
+__via Delta:__
+```
+"get": [{
+    "path": "resources.notes"
+}]
+
+"get": [{
+    "path": "resources.notes.urn:mrn:signalk:uuid:36f9b6b5-959f-46a1-8a68-82159742aadd"
+}]
+```
+---
+#### CREATING NOTES
+
+__via HTTP:__
+
+Send a __POST__ request containing the note's details.
+```json
+POST http://localhost:3000/signalk/v1/api/vessels/resources/notes
+{
+    "value": { 
+        "title": "Dusky Shoal",
+        "description": "Anchoring information for Dsuky Shoal.....",
+        "authors": [
+            {
+                "name": "Ian West"
+            }
+        ],             
+        "geohash": "rbejg:Big Island",

+            "type": "manual"
+        } 
+    }
+}
+```
+
+__via Delta:__
+
+Send a __PUT__ request containing the note's details.
+```json
+{
+  "requestId": "6b0e776f-811a-4b35-980e-b93405371bc5",

+  }]
+}
+```
+---
+
+#### UPDATING NOTES
