 [pygeoapi](https://pygeoapi.io) is a Python server implementation of the [OGC API](https://ogcapi.ogc.org) suite of standards. The project emerged as part of the next generation OGC API efforts in 2018 and provides the capability for organizations to deploy a RESTful OGC API endpoint using OpenAPI, GeoJSON, and HTML. pygeoapi is [open source](https://opensource.org/) and released under an [MIT license](https://github.com/geopython/pygeoapi/blob/master/LICENSE.md).
 
 Please read the docs at [https://docs.pygeoapi.io](https://docs.pygeoapi.io) for more information.
+
+# Speckle implementation of pygeoapi
+
+## How to use Speckle data through OGC API Features
+
+This is the test deployment of the OGC API server for public Speckle projects. It allows you to share your Speckle model as geospatial data in the format of OGC API Features / Web Feature Service, so it can be natively added to a QGIS, ArcGIS or Civil3D project, or embedded into a web map using Leaflet, OpenLayers or other libraries. 
+
+Demo page: https://geo.speckle.systems/ 
+
+### How to construct a valid URL to get georeferenced Speckle layer
+URL should start with 'https://geo.speckle.systems/?' followed by required and optional parameters. Parameters should be separated with '&' symbol. You can use the generated link to access OGC API dataset in your preferred software, as well as explore the data in the browser and share with others. 
+
+Use the following URL parameters to construct a link that provides Speckle data with your preferred settings::
+ - speckleUrl (text), required, should contain path to a specific Model in Speckle Project, e.g. 'https://app.speckle.systems/projects/55a29f3e9d/models/2d497a381d'
+ - dataType (text), optional, choose from: points, lines, polygons or projectcomments
+ - limit (positive integer), recommended, as some applications might apply their custom feature limit
+ - preserveAttributes (string), optional, choose from: true, false. If not set, meshes will be split into separate polygons for better display quality.
+ - crsAuthid (text), an authority string e.g. 'epsg:4326'. If set, LAT, LON and NORTHDEGREES arguments will be ignored.
+ - lat (number), in range -90 to 90
+ - lon (number), in range -180 to 180
+ - northDegrees (number), in range -180 to 180
+If GIS-originated Speckle model is loaded, no location arguments are needed.  
+
+Example: [https://geo.speckle.systems/?speckleUrl=https://app.speckle.systems/projects/64753f52b7/models/338b386787&lat=-0.031405&lon=109.335828](https://geo.speckle.systems/?speckleUrl=https://app.speckle.systems/projects/64753f52b7/models/338b386787&lat=-0.031405&lon=109.335828)
+
+
+### Troubleshooting
+
+List of possible issues you can experience and solutions to them:
+
+- Page or Map stays blank and Developer Tools Console shows "net::ERR_QUIC_PROTOCOL_ERROR 200 (OK)"
+
+Solution: Try reloading the page. Otherwise, if in Google Chrome, navigate to chrome://flags/#enable-quic and change Experimental QUIC Protocol dropdown to Disabled.
+
+- Model seems to be loaded incomplete
+
+Solution: Check the message "feature count limited to ..." next to the Model name on the top of the page. If the message is present, try increasing the feature limit using "&limit=10000" URL parameter
+
+- Attribute table doesn't have original feature attributes and properties
+
+Solution: Enable the URL parameter "&preserveAttributes=true". It is disabled by default due to the faulty display of the 3-dimentional multiPolygons overlapping themselves in 2d space, when viweving in the browser on 2d map. Enabling this parameter might make the multipolygons appear "transparent" due to self-overlap. 
+
+Report any other issues here or on our [Community Forum](https://speckle.community/).
+
+## Add Speckle Feature Layers to web-based maps and desktop apps
+
+### Add Speckle layer in Javascript
+
+Javascript-based mapping libraries can load speckle data as JSON using the following function: 
+
+```javascript
+    async function loadSpeckleData() => {
+        var speckle_model_url = 'https://geo.speckle.systems/?speckleUrl=https://app.speckle.systems/projects/344f803f81/models/5582ab673e&datatype=polygons';
+        const speckle_data = await fetch(speckle_model_url, {
+            headers: {'Accept': 'application/geo+json'}
+        }).then(response => response.json());
+    }
+```
+
+Then you can add it to the base map (e.g. using Leaflet and OpenStreetMap basemap tiles). The following example assumes an html div element with id="items-map":
+
+```html
+    <script>
+        var map = L.map('items-map').setView([ 45 ,  -75 ], 5);
+        map.addLayer(new L.TileLayer(
+            'https://tile.openstreetmap.org/{z}/{x}/{y}.png', {
+                maxZoom: 22,
+                attribution: '&copy; <a href="https://openstreetmap.org/copyright">OpenStreetMap contributors</a> &copy; Data: <a href="https://speckle.systems/">Speckle Systems</a>'
+            }
+        ));
+        loadSpeckleData();
+
+        async function loadSpeckleData() => {
+            var speckle_model_url = 'https://geo.speckle.systems/?speckleUrl=https://app.speckle.systems/projects/344f803f81/models/5582ab673e&datatype=polygons';
+            const speckle_data = await fetch(speckle_model_url, {
+                headers: {'Accept': 'application/geo+json'}
+            }).then(response => response.json());
+            
+            speckle_layer = L.geoJSON(speckle_data, {
+                onEachFeature: function (feature, layer) {
+                    layer.setStyle({
+                        fillColor: feature.displayProperties['color'],
+                        color: myFillColor,
+                        fillOpacity: 0.8,
+                        weight: feature.displayProperties['lineWidth'],
+                        radius: feature.displayProperties['radius']
+                    });
+                }
+            });
+
+            speckle_layer.addTo(map);
+            map.fitBounds(speckle_layer.getBounds())
+        };
+    </script>
+```

+### Add Speckle WFS layer in QGIS
+1. Add new WFS Layer
+
+![image](https://github.com/user-attachments/assets/ea168853-dc97-43bf-b9f2-4d0244addb01)
+
+2. Create New connection, specify the name and URL with mandatory "speckleUrl" parameter pointing to the Speckle Model. Preferably add the URL parameter with the custom feature limit (e.g. '&limit=10000'). Then click Detect, and the WFS Version should display "OGC API Features". Click OK.
+
+![image](https://github.com/user-attachments/assets/8bf9f164-bdb1-455e-8298-f0c1d5dd324d)
+
+3. Connect, select the dataset "Speckle data" and click "Add".
+
+![image](https://github.com/user-attachments/assets/73c97729-f3b3-4192-a4cf-667ba147fc6f)
+
+4. Loading of the data might take a minute, then you will be able to Zoom to layer and check the Attribute table. Done!
