+# Apex Editor
+
+## Compiling and running
+As Apex Editor is a Spring Boot application, it may be compiled and run using:
+```
+mvn spring-boot:run
+```
+Alternatively, you may build and run a jar:
+```
+mvn clean install
+java -jar target/gui-editor-apex-2.2.1-SNAPSHOT-exec.jar
+```
+Once started, navigate to http://localhost:8080/.
+
+There are some sample models in _src/test/resources/models_
+
+### Build artifacts
+Note maven produces two jars:
+- a regular jar that we can include in other modules: _gui-editor-apex-VERSION.jar_
+- an executable spring boot jar with the suffix 'exec': _gui-editor-apex-VERSION-exec.jar_
+
+## Setting upload URL and user ID
+There are two Spring properties for Apex Editor:
+- `apex-editor.upload-url` sets the URL for the model upload feature.
+- `apex-editor.upload-userid` sets the default userId for uploads.
+
+These may be set in a Spring properties file:
+```
+server.port=18989
+apex-editor.upload-url=http://localhost:12345
+apex-editor.upload-userid=DefaultUser
+```
+
+### Overriding upload user ID at runtime
+To override the upload userId for your session, append `?userId=YourId` to the URL,
+e.g. http://localhost:18989/?userId=MyUser

- * where the {@code int} path parameter {@code session} is assigned the {@code int} value {@code 109} <li>The path
- * {@code ContextSchema/Update} redirects this call to the method {@link #updateContextSchema(String)}, which should be
- * a {@link javax.ws.rs.PUT}, with a single String in the body/payload which gets mapped to the single String parameter
- * for the method. <li>So, in summary, the REST request updates a {@code ContextSchema} as specified in the payload for
