+
+## Global Options
+
+It's recommended to define the global options in your [Base Model](/configuration#creating-a-base-model), 
+in order to abstract configuration from your models.
+
+### `$http`
+- Returns: `HTTP Client Instance`
+
+Instance of the HTTP client which is used to make requests.
+
+See [Installation](/installation)
+
+### `baseURL`
+- Returns: `string`
+
+Base URL which is used and prepended to make requests.
+
+See [Configuration](/configuration#creating-a-base-model)
+
+```js
+baseURL() {
+  return 'http://my-api.com'
+}
+```
+
+### `request`
+- Arguments: `(config)`
+- Returns: `HTTP Client Request`
+
+Request method which is used to make requests.
+
+See [Configuration](/configuration#creating-a-base-model)
+
+```js
+request(config) {
+  return this.$http.request(config)
+}
+```
+
+### `parameterNames`
+- Returns: `object`
+
+This method can be overridden in the model to customize the name of the query parameters.
+
+See [Configuration](/configuration#customizing-query-parameters)
+
+```js
+parameterNames() {
+  return {
+    include: 'include',
+    filter: 'filter',
+    sort: 'sort',
+    fields: 'fields',
+    append: 'append',
+    page: 'page',
+    limit: 'limit'
+  }
+}
+```
+
+#### `include`
+- Default: `include`
+- Returns: `string`
+
+#### `filter`
+- Default: `filter`
+- Returns: `string`
+
+#### `sort`
+- Default: `sort`
+- Returns: `string`
+
+#### `fields`
+- Default: `fields`
+- Returns: `string`
+
+#### `append`
+- Default: `append`
+- Returns: `string`
+
+#### `page`
+- Default: `page`
+- Returns: `string`
+
+#### `limit`
+- Default: `limit`
+- Returns: `string`
+
+## Model Options
+
+These are model-related options.
+
+### `resource`
+- Returns: `string`
+
+Resource route of the model which is used to build the query.
+
+See [Configuration](/configuration#creating-the-domain-models)
+
+```js
+resource() {
+  return 'resource'
+}
+```
+
+### `primaryKey`
+- Default: `id`
+- Returns: `string`
+
+Primary key of the model which is used to build the query.
+
+See [Configuration](/configuration#changing-the-primary-key)
+
+```js
+primaryKey() {
+  return 'id'
+}
+```
+
+### `relations`
+- Returns: `object`
+
+This method can be implemented in the model to apply model instances to eager loaded relationships. 
+It works for collections too.
+
+It must return an object, which the key is the property of the relationship, and the value is the
+model instance.
+
+See [Configuration](/configuration#eager-loaded-relationships)
+
+```js
+relations() {
+  return {
+    comments: Comment
+  }
+}
+```
+
+### `hasMany`
+- Arguments: `(model)`
+- Returns: `Model`
+
+This method can be used to lazy load relationships of a model and apply model instances to them.
+
+It must receive a model instance as argument.
+
+See [Configuration](/configuration#lazy-loading-relationships)
+
+```js
+comments() {
+  return this.hasMany(Comment)
+}
+```
