+# The `stdlib_filesystem` module
+
+[TOC]
+
+## Introduction
+
+Module for filesystem interactions.
+
+## Constants
+
+### `is_windows``
+
+Boolean constant indicating whether the current platform is Windows.
+
+### `path_separator``
+
+Character constant representing the path separator for the current platform. On Windows, it is `\`. On other platforms, it is `/`.
+
+## Procedures
+
+### `exists`
+
+#### Status
+
+Experimental
+
+#### Description
+
+Determines if a file or directory exists at the given path by returning a logical value.
+
+#### Syntax
+
+`exists = ` [[stdlib_filesystem(module):exists(function)]] `(path)`
+
+#### Arguments
+
+`path`: Shall be a character expression containing the path to a file or directory to check for existence.
+
+#### Return value
+
+A logical value indicating whether a file or directory exists at the given path.
+
+### `list_dir`
+
+#### Status
+
+Experimental
+
+#### Description
+
+Lists the contents of a directory.
+
+#### Syntax
+
+`call ` [[stdlib_filesystem(module):list_dir(subroutine)]] `(dir, files[, iostat][, iomsg])`
+
+#### Arguments
+
+`dir`: Shall be a character expression containing the path to the directory to list.
+
+`files`: Shall be an allocatable rank-1 array of type `string_type` that will contain the names of the files and directories in the directory.
+
+`iostat`: Shall be a scalar of type `integer` that receives the error status of `list_dir`. Optional argument.
+
+`iomsg`: Shall be a deferred length character variable that receives the error message of `list_dir`. Optional argument.
+
+### `mkdir`
+
+#### Status
+
+Experimental
+
+#### Description
+
+Creates a new directory.
+
+#### Syntax
+
+`call ` [[stdlib_filesystem(module):mkdir(subroutine)]] `(dir[, iostat][, iomsg])`
+
+#### Arguments
+
+`dir`: Shall be a character expression containing the path to the directory to create.
+
+`iostat`: Shall be a scalar of type `integer` that receives the error status of `mkdir`. Optional argument.
+
+`iomsg`: Shall be a deferred length character variable that receives the error message of `mkdir`. Optional argument.
+
+### `rmdir`
+
+#### Status
+
+Experimental
+
+#### Description
+
+Removes a directory.
+
+#### Syntax
+
+`call ` [[stdlib_filesystem(module):rmdir(subroutine)]] `(dir)`
+
+#### Arguments
+
+`dir`: Shall be a character expression containing the path to the directory to remove.
+
+### `run`
+
+#### Status
+
+Experimental
+
+#### Description
+
+Runs a command in the shell.
+
+#### Syntax
+
+`call ` [[stdlib_filesystem(module):run(subroutine)]] `(command[, iostat][, iomsg])`
+
+#### Arguments
+
+`command`: Shall be a character expression containing the command to run in the shell.
+
+`iostat`: Shall be a scalar of type `integer` that receives the error status of `run`. Optional argument.
+
+`iomsg`: Shall be a deferred length character variable that receives the error message of `run`. Optional argument.
