+In addition, since the JSON file is structured like a typical REST API data structure, the following endpoints will work:
 
 * `GET http://localhost:8080/notes` - retrive all "notes"
 * `GET http://localhost:8080/notes/1` - retrive the note with the `id`   of `1`
-* `POST http://localhost:8080/notes/` - Create a new note. This modifies the `data.json` file.
+* `POST http://localhost:8080/notes/` with JSON payload - Create a new note. This modifies the `data.json` file.
+* `PUT/PATCH http://localhost:8080/notes/1` with JSON payload - update the note with the `id`   of `1`. This modifies the `data.json` file.
 * `DELETE http://localhost:8080/notes/1` - Delete the note with the `id`   of `1`. This modifies the `data.json` file.
 
+
+Anything that doesn't match returns a `404` status code.
+
+## Examples with `curl`
+
+Given the following data file:
+
+
+```json
+{
+  "notes" : [
+    {
+      "id" : 1,
+      "title" : "Hello World"
+    },
+    {
+      "id" : 2,
+      "title" : "The second note"
+    }
+  ]
+}
+```
+
+To get everything:
+
+```
+curl -i localhost:8080/
+```
+
+To get the `notes` node:
+
+
+```
+curl -i localhost:8080/notes
+```
+
+To get the `notes/1` node:
+
+
+```
+curl -i localhost:8080/notes/1
+```
+
+To add a new note:
+
+```
+curl -i -X POST http://localhost:8080/notes \
+-H "Content-type: application/json" \
+-d '{"title": "This is another note"}'
+```
+
+To update the contents of the first note:
+
+```
+curl -i -X PUT http://localhost:3000/notes/1  \
+-H "Content-type: application/json" \
+-d '{"title": "This is the third note"}'
+```
+
+To delete the third note:
+
+```
+curl -i -X DELETE localhost:3000/notes/3
+```
+
+If you use a different JSON file, your paths will be different.
+
+### Advanced Usage
+
+To specify a different port, use the `-p` option:
+
+```
+demo-api -p 4000
+```
+
+To specify a different filename, in case you don't like `data.json` as the default, use `-f` and specify the file:
+
+
+```
+demo-api -f notes.json
+```
+
+To view the version, use `-v`:
+
+```
+demo-api -v
+```
+
 ## Installation
 
 To install, download the latest release to your system and copy the executable to a location on your path. Then launch it in a directory containing `data.json`.
 
 
 ## Roadmap
 
-* `PUT/PATCH` support
-* tests
-* refactoring
+* Refactoring. This code is a mess.
+* A "no persist" mode - changes are accepted but not saved to the JSON file.
