+## Full version

+Which files are needed when using the full version?

+- jsoneditor.map (optional, for debugging purposes only)

+
+## Minimalist version
+
+The minimalist version has excluded the following libraries:
+
+- `ace` (via `brace`), used for the code editor.
+- `ajv`, used for JSON schema validation.
+
+This reduces the the size of the minified and gzipped JavaScript file from
+about 160 kB to just 25 kB.
+
+When to use the minimalist version?
+
+- If you don't need the mode "code" and don't need JSON schema validation.
+- Or if you want to provide `ace` and/or `ajv` yourself via the configuration
+  options, for example when you already use Ace in other parts of your
+  web application too and don't want to bundle the library twice.
