 ```
-Usage: remixd -s <shared folder>
+> remixd -h
+Usage: remixd [options]
 
-Provide a two-way connection between the local computer and Remix IDE
+Establish a two-way websocket connection between the local computer and Remix IDE for a folder
 
 Options:
   -v, --version               output the version number
-  -u, --remix-ide  <url>      URL of remix instance allowed to connect to this web sockect connection
-  -s, --shared-folder <path>  Folder to share with Remix IDE
+  -u, --remix-ide  <url>      URL of remix instance allowed to connect
+  -s, --shared-folder <path>  Folder to share with Remix IDE (Default: CWD)
+  -i, --install <name>        Module name to install locally (Supported: ["slither"])
   -r, --read-only             Treat shared folder as read-only (experimental)
   -h, --help                  output usage information
 
 Example:
 
-    remixd -s ./ -u http://localhost:8080
+    remixd -s ./shared_project -u http://localhost:8080
 
 ```
 
-## SHARE A FOLDER
+## Share a project directory
 
-`remixd -s <absolute-path> --remix-ide https://remix.ethereum.org`
+`remixd -s ./shared_project -u https://remix.ethereum.org`
 
 The current user should have `read/write` access to the folder (at least `read` access).
 
 It is important to notice that changes made to the current file in `Remix IDE` are automatically saved to the local computer every 5000 ms. There is no `Save` action. But the `Ctrl-Z` (undo) can be used.
 
-Furthermore :
+Furthermore:
  - No copy of the shared folder are kept in the browser storage.
- - It is not possible to create a file from `Remix IDE` (that might change).
+ - Clicking on the new folder or new file icon under localhost will create a new file or folder in the shared folder.
  - If a folder does not contain any file, the folder will not be displayed in the explorer (that might change).
  - Symbolic links are not forwarded to Remix IDE.

+
+- **65520** : For `remixd` websocket listener, to share a project from local device with Remix IDE. Shared folder will be loaded in the Remix IDE File Explorer workspace named localhost [See more](https://remix-ide.readthedocs.io/en/latest/remixd.html)
+- **65522** : For `Hardhat` websocket listener, to enable the Hardhat Compilation using Remix IDE Solidity Compiler plugin, if shared folder is a Hardhat project [See more](https://remix-ide.readthedocs.io/en/latest/hardhat.html)
+- **65523** : For `Slither` websocket listener, to enable the Slither Analysis using Remix IDE Solidity Static Analysis plugin [See more](https://remix-ide.readthedocs.io/en/latest/slither.html)
+- **65524** : For `Truffle` websocket listener, to enable the Truffle Compilation using Remix IDE Solidity Compiler plugin, if shared folder is a Truffle project [See more](https://remix-ide.readthedocs.io/en/latest/truffle.html)
