 ## ☁️ Sia Provider
 
 - Uses the **renterd HTTP REST API** via `libcurl`

-## 🔒 Encryption Provider (WIP — Use With Caution)
+## 🔗 Remote Mount Provider
+
+Connects to a **different machine running Repertory** and exposes its active mount locally. This is a **client** that talks to a Repertory **server** which has remote mounting enabled.
+
+### How it works (high level)
+
+- **Server side**: an existing S3 or Sia mount is configured to allow remote access via the `RemoteMount` section of its config.
+- **Client side**: you mount using `-rm host:port`, and the client forwards file operations over a secure packet channel with a **shared EncryptionToken**.
+
+### Required settings
+
+- **Server (on the original S3/Sia mount) — `RemoteMount` section**
+  - `RemoteMount.Enable` — `true` to expose the mount.
+  - `RemoteMount.ApiPort` — listening port for remote clients.
+  - `RemoteMount.ClientPoolSize` — size of server's client pool. *(default **20**)*
+  - `RemoteMount.EncryptionToken` — **shared secret**; must match the client's token.
+
+- **Client — `RemoteConfig` section**
+  - `RemoteConfig.HostNameOrIp` — server address.
+  - `RemoteConfig.ApiPort` — server remote API port.
+  - `RemoteConfig.EncryptionToken` — **same value** as the server.
+  - `RemoteConfig.MaxConnections` — max concurrent connections. *(default **20**)*
+  - `RemoteConfig.ReceiveTimeoutMs` — receive timeout in ms. *(default **120000**)*
+  - `RemoteConfig.SendTimeoutMs` — send timeout in ms. *(default **30000**)*
+
+**Default Remote API ports** (from source):
+
+| Provider | Default Remote API Port |
+|---------|--------------------------|
+| Sia     | 20000                    |
+| Remote  | 20010                    |
+| S3      | 20100                    |
+| Encrypt | 20001                    |

+## 🔒 Encrypt Provider (WIP — Use With Caution)
 
 - Acts as a **local pass-through provider** - configure it to use any existing folder on your file system and it will transparently encrypt file/directory names and file data using `XChaCha20-Poly1305`.
 - **Important:** There is currently **no decryption provider**. Data encrypted this way cannot be decrypted by Repertory; additional support is planned for future versions.
