+## SDK Configuration Options
+
+<ParamField path="client-class-name" type="string" default="<Organization>ApiClient" required={false}>
+
+The provided string will be used as the client class name.
+</ParamField>
+
+<ParamField path="base-api-exception-class-name" type="string" required={false}>
+</ParamField>
+
+<ParamField path="base-exception-class-name" type="string" required={false}>
+</ParamField>
+
+<ParamField path="custom-dependencies" type="List<string>" required={false}>
+
+Example:
+
+    ```yaml
+    custom-dependencies:
+    - "implementation com.foo:bar:0.0.0"
+    - "testImplementation com.foo:bar:0.0.0"
+    - "api com.foo:bar:0.0.0"
+    ```
+
+</ParamField>
+
+<ParamField path="publish-to" type="'central' | 'ossrh'" required={false}>
+</ParamField>
+
+<ParamField path="inline-file-properties" type="boolean" default="false" required={false}>
+</ParamField>
+
+<ParamField path="wrapped-aliases" type="boolean" default="false" required={false}>
+  When enabled, generates wrapper types for each alias to increase type-safety.
+For example, if you have an alias `ResourceId: string` then if this is true, the
+generator will generate a `ResourceId.java` file. If false, it will just treat it
+as `java.util.String`.
+</ParamField>
+
+<ParamField path="enable-forward-compatible-enums" type="boolean" default="false" required={false}>
+</ParamField>
+
+<ParamField path="generate-unknown-as-json-node" type="boolean" default="false" required={false}>
+</ParamField>
+
+<ParamField path="json-include" type="'non-empty' | 'non-absent'" default="non-absent" required={false}>
+</ParamField>
+
+<ParamField path="enable-public-constructors" type="boolean" default="false" required={false}>
+
+When enabled, generates public constructors for model types.
+</ParamField>
+
+<ParamField path="disable-required-property-builder-checks" type="boolean" default="false" required={false}>
+</ParamField>
+
+<ParamField path="inline-path-parameters" type="boolean" default="false" required={false}>
+</ParamField>
+
+<ParamField path="enable-inline-types" type="boolean" default="false" required={false}>

+</ParamField>
+
+<ParamField path="package-layout" type="'nested' | 'flat'" default="nested" required={false}>
+</ParamField>
