+# Features
+
+Below is a non-exhaustive listing of the features available to a server instance,
+depending on the chosen configuration.
+The core feature of the CSS is that it uses **dependency injection** to configure its components,
+so any of the features below can always be adapted or replaced with custom components if required.
+It can also be used to configure dummy components for debugging, development, or experimentation purposes.
+See this [tutorial](https://github.com/CommunitySolidServer/tutorials/blob/main/custom-configurations.md)
+and/or this [example repository](https://github.com/CommunitySolidServer/hello-world-component)
+for more information on that.
+
+To generate configurations with some of these features enabled/disabled,
+you can use the **[configuration generator](https://communitysolidserver.github.io/configuration-generator/)**.
+
+## Authentication
+
+Clients are identified based on the contents of **DPoP** tokens,
+as described in the [**Solid-OIDC** specification](https://solidproject.org/TR/oidc).
+
+The server also provides several dummy components that can be used here,
+to either always identify the client as a fixed WebID,
+or to allow the WebID to be set directly in the `Authorization` header.
+These can be configured by changing the `ldp/authentication` import in your configuration.
+
+## Authorization
+
+Two authorization mechanisms are implemented for determining who has access to resources:
+
+* **[Web Access Control](https://solidproject.org/TR/wac)**
+* **[Access Control Policy](https://solidproject.org/TR/acp)**
+
+Alternatively, the server can be configured to not have any kind of authorization and allow full access to all resources.
+
+## Solid Protocol
+
+The **[Solid Protocol](https://solidproject.org/TR/protocol)** is supported.
+
+Requests to the server support **content negotiation** for common RDF formats.
+
+Binary **[range headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Range)** are supported.
+
+[`ETag`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag) and `Last-Modified` headers are supported.
+These can be used for **[conditional requests](https://developer.mozilla.org/en-US/docs/Web/HTTP/Conditional_requests)**.
+
+`PATCH` requests targeting RDF resources can be made with **N3 Patch** or **SPARQL Update** bodies.
+
+The server can be configured to store data in **memory**, on the **file system**, or through a **SPARQL endpoint**.
+Similarly, the locking system that is used to prevent data conflicts
+can be configured to store locks in memory, on the file system, or in a Redis store, or it can be disabled.
+
+Multiple **worker threads** can be used when starting the server.
+
+## Account management
+
+Accounts can be created on the server with which users can perform the following actions,
+through either a **JSON** or an **HTML** API:
+
+* Add **email/password** combinations which can be used to log in.
+* Create **pods**, which are containers on the server over which the user has full control.
+* Link **WebIDs** to the account. When using [Solid-OIDC](https://solidproject.org/TR/oidc),
+  the user can identify as any of these.
+  For external WebIDs, the server requires the user to add a triple as identification,
+  but this can be disabled if needed.
+* Create **client credentials**, which can be used to authenticate without using the browser.
+  More information on these can be found [here](usage/client-credentials.md).
+* It is possible to use Solid-OIDC to limit access to certain parts of the account API.
+  More information on this can be found [here](usage/identity-provider.md#access).
+
+Using these accounts, the server can generate tokens
+to support **[Solid-OIDC](https://solidproject.org/TR/oidc)** authentication.
+
+### Pods
+
+The server keeps track of the **pod owners**,
+which is a list of WebIDs which have full control access over all resources contained within.
+Owners can be added to and removed from a pod.
+
+Pod URLs can be minted as either
+**subdomain**, `http://pod.example.com/`, or **suffix**, `http://example.com/pod/`.
+
+When starting the server, a configuration file can be provided
+to immediately create one or more accounts on the server with their own pods.
+See the [documentation](usage/seeding-pods.md) for more information.
+
+## Notifications
+
+CSS supports v0.2.0 of the **[Solid Notifications Protocol](https://solidproject.org/TR/notifications-protocol)**.
+Specifically it supports the Notification Types
+[WebSocketChannel2023](https://solid.github.io/notifications/websocket-channel-2023)
+and [WebhookChannel2023](https://solid.github.io/notifications/webhook-channel-2023).
+
+More documentation on notifications can be found [here](usage/notifications.md).
