+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+
+This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
+
+The version of the OpenAPI document: 1.0.0
+
+## Building
+
+To install the required dependencies and to build the typescript sources run:
+
+```console
+npm install
+npm run build
+```
+
+## Publishing
+
+First build the package then run `npm publish dist` (don't forget to specify the `dist` folder!)
+
+## Consuming
+
+Navigate to the folder of your consuming project and run one of next commands.
+
+_published:_
+
+```console
+npm install sample-angular-20-0-0@1.0.0 --save
+```
+
+_without publishing (not recommended):_
+
+```console
+npm install PATH_TO_GENERATED_PACKAGE/dist.tgz --save
+```
+
+_It's important to take the tgz file, otherwise you'll get trouble with links on windows_
+
+_using `npm link`:_
+
+In PATH_TO_GENERATED_PACKAGE/dist:
+
+```console
+npm link
+```
+
+In your project:
+
+```console
+npm link sample-angular-20-0-0
+```
+
+__Note for Windows users:__ The Angular CLI has troubles to use linked npm packages.
+Please refer to this issue <https://github.com/angular/angular-cli/issues/8284> for a solution / workaround.
+Published packages are not effected by this issue.
+
+### General usage
+
+In your Angular project:
+
+```typescript
+
+import { ApplicationConfig } from '@angular/core';
+import { provideHttpClient } from '@angular/common/http';
+import { provideApi } from 'sample-angular-20-0-0';
+
+export const appConfig: ApplicationConfig = {
+    providers: [
+        // ...
+        provideHttpClient(),
+        provideApi()
+    ],
+};
+```
+
+**NOTE**
+If you're still using `AppModule` and haven't [migrated](https://angular.dev/reference/migrations/standalone) yet, you can still import an Angular module:
+```typescript
+import { ApiModule } from 'sample-angular-20-0-0';
+```
+
+If different from the generated base path, during app bootstrap, you can provide the base path to your service.
+
+```typescript
+import { ApplicationConfig } from '@angular/core';
+import { provideHttpClient } from '@angular/common/http';
+import { provideApi } from 'sample-angular-20-0-0';
+
+export const appConfig: ApplicationConfig = {
+    providers: [
+        // ...
+        provideHttpClient(),
+        provideApi('http://localhost:9999')
+    ],
+};
+```
+
+```typescript
+// with a custom configuration
+import { ApplicationConfig } from '@angular/core';
+import { provideHttpClient } from '@angular/common/http';
+import { provideApi } from 'sample-angular-20-0-0';
+
+export const appConfig: ApplicationConfig = {
+    providers: [
+        // ...
+        provideHttpClient(),
+        provideApi({
+            withCredentials: true,
+            username: 'user',
+            password: 'password'
+        })
+    ],
+};
+```
+
+```typescript
+// with factory building a custom configuration
+import { ApplicationConfig } from '@angular/core';
+import { provideHttpClient } from '@angular/common/http';
+import { provideApi, Configuration } from 'sample-angular-20-0-0';
+
+export const appConfig: ApplicationConfig = {
+    providers: [
+        // ...
+        provideHttpClient(),
+        {
+            provide: Configuration,
+            useFactory: (authService: AuthService) => new Configuration({
+                    basePath: 'http://localhost:9999',
+                    withCredentials: true,
+                    username: authService.getUsername(),
+                    password: authService.getPassword(),
+            }),
+            deps: [AuthService],
+            multi: false
+        }
+    ],
+};
+```
+
+### Using multiple OpenAPI files / APIs
+
+In order to use multiple APIs generated from different OpenAPI files,
+you can create an alias name when importing the modules
+in order to avoid naming conflicts:
+
+```typescript
+import { provideApi as provideUserApi } from 'my-user-api-path';
+import { provideApi as provideAdminApi } from 'my-admin-api-path';
+import { HttpClientModule } from '@angular/common/http';
+import { environment } from '../environments/environment';
+
+export const appConfig: ApplicationConfig = {
+    providers: [
+        // ...
+        provideHttpClient(),
+        provideUserApi(environment.basePath),
+        provideAdminApi(environment.basePath),
+    ],
+};
+```
+
+### Customizing path parameter encoding
+
+Without further customization, only [path-parameters][parameter-locations-url] of [style][style-values-url] 'simple'
+and Dates for format 'date-time' are encoded correctly.
+
+Other styles (e.g. "matrix") are not that easy to encode
+and thus are best delegated to other libraries (e.g.: [@honoluluhenk/http-param-expander]).
+
+To implement your own parameter encoding (or call another library),
+pass an arrow-function or method-reference to the `encodeParam` property of the Configuration-object
+(see [General Usage](#general-usage) above).
+
+Example value for use in your Configuration-Provider:
+
+```typescript
+new Configuration({
+    encodeParam: (param: Param) => myFancyParamEncoder(param),
+})
+```
