 # graphql-go-tutorial
 A go implementation of the graphql server, that is compatible with the Apollo demo: https://github.com/apollographql/graphql-tutorial
 
+## Running the GraphQL server
+The server runs on port 400.  To run execute
+
+    $ go run  
+
 ## Testing with Curl
 The server can be tested using curl.   The query and mutations are described in the sub-sections below.   In each case you can use the following curl command to  POST the requests.  You can optionally pass the response through jq to make it easier to read.
 
-    curl -XPOST http://locahost:4000 -H 'Content-Type: application/json' -d \
+    curl -XPOST http://localhost:4000/graphql -H 'Content-Type: application/json' -d \
     '
        <pay load goes here>

+## Testing with Apollo GraphQL Tutorial
+Checkout the apollo Tutorial.
+
+    git clone  https://github.com/apollographql/graphql-tutorial
+
+Switch to the t7-end branch
+
+    cd graphql-tutorial
+    git checkout t7-end
+
+With the golang server running, start the apollo Client.  
+
+    cd client
+    npm install && npm start
+
+The browser should open on localhost:3000.  You can now use the UI to test drive the server.
