 # Remixd
 
-`remixd` is a tool that intend to be used with [Remix IDE](https://github.com/ethereum/remix-project) (aka. Browser-Solidity). It allows a websocket connection between
-`Remix IDE` (web application) and the local computer.
+`remixd` is an NPM module that intends to be used with [Remix IDE](https://remix.ethereum.org/) web and desktop applications. It establishes a two-way websocket connection between the local computer and Remix IDE for a particular project directory.
 
-Practically Remix IDE makes available a folder shared by `remixd`.
+`remixd` can be used to setup a development environment with other popular frameworks like Hardhat, Truffle, Slither etc.
 
-More details are explained in this [tutorial](https://remix-ide.readthedocs.io/en/latest/remixd.html).
+More details are explained in the [documentation](https://remix-ide.readthedocs.io/en/latest/remixd.html).
 
-Alternatively `remixd` can be used to setup a development environment that can be used with other popular frameworks like Embark, Truffle, Ganache, etc..
+## Installation
 
-`remixd` needs `npm` and `node`
+`npm install -g @remix-project/remixd`
 
-## INSTALLATION
+NOTE: When the remixd NPM module is installed, it also installs [Slither](https://github.com/crytic/slither), [solc-select](https://github.com/crytic/solc-select#quickstart) and sets [solc](https://docs.soliditylang.org/en/latest/installing-solidity.html) to latest version i.e. 0.8.15 currently.
 
-`yarn global add @remix-project/remixd`
+ALSO NOTE: Python3.6+ (pip3) needs to already be installed on the System. In case of any discrepany, Slither can also installed along with other dependencies using command:
+```
+> remixd -i slither
+``` 
+
+_(This packaging of Slither with the remixd module is supported since Remixd v0.6.3)_

+## remixd command
 
-## HELP SECTION
+The remixd command without options shares present working directory and the shared Remix domain will be https://remix.ethereum.org, https://remix-alpha.ethereum.org, or https://remix-beta.ethereum.org
 
+The remixd command is:
+```
+> remixd
 ```
-Usage: remixd -s <shared folder>
 
-Provide a two-way connection between the local computer and Remix IDE
+If you are using Remix from localhost or you are not running the command from your working directory, you’ll need to use the command with flags.
+
+```
+> remixd -h
+Usage: remixd [options]
+
+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.

+remixd creates a websocket connections with Remix IDE on different ports. Ports are defined according to specific purpose. Port usage details are as:
+
+- **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)
+
+Note: Please make sure your system is secured enough and these ports are not opened nor forwarded.
