+## Coder Settings
+
+The Coder Settings allows users to control CLI download behavior, SSH configuration, TLS parameters, and data
+storage paths. The options can be configured from the plugin's main Workspaces page > deployment action menu > Settings.
+
+### CLI related settings 
+
+```Binary source``` specifies the source URL or relative path from which the Coder CLI should be downloaded.
+If a relative path is provided, it is resolved against the deployment domain.
+
+```Enable downloads``` allows automatic downloading of the CLI if the current version is missing or outdated.
+
+```Binary directory``` specifies the directory where CLI binaries are stored. If omitted, it defaults to the data directory.
+
+```Enable binary directory fallback``` if enabled, falls back to the data directory when the specified binary
+directory is not writable.
+
+```Data directory``` directory where plugin-specific data such as session tokens and binaries are stored if not 
+overridden by the binary directory setting.
+
+```Header command``` command that outputs additional HTTP headers. Each line of output must be in the format key=value.
+The environment variable CODER_URL will be available to the command process.
+
+### TLS settings
+
+The following options control the secure communication behavior of the plugin with Coder deployment and its available API.
+
+```TLS cert path``` path to a client certificate file for TLS authentication with Coder deployment.
+The certificate should be in X.509 PEM format.
+
+```TLS key path``` path to the private key corresponding to the TLS certificate from above.
+The certificate should be in X.509 PEM format.
+
+```TLS CA path``` the path of a file containing certificates for an alternate certificate authority used to verify TLS
+certs returned by the Coder deployment. The file should be in X.509 PEM format. This option can also be used to verify
+proxy certificates.
+
+```TLS alternate hostname``` overrides the hostname used in TLS verification. This is useful when the hostname 
+used to connect to the Coder deployment does not match the hostname in the TLS certificate.
+
+### SSH settings
+
+The following options control the SSH behavior of the Coder CLI.
+
+```Disable autostart``` adds the --disable-autostart flag to the SSH proxy command, preventing the CLI from keeping
+workspaces constantly active.
+
+```Enable SSH wildcard config``` enables or disables wildcard entries in the SSH configuration, which allow generic
+rules for matching multiple workspaces.
+
+```SSH proxy log directory``` directory where SSH proxy logs are written. Useful for debugging SSH connection issues.
+
+```SSH network metrics directory``` directory where network information used by the SSH proxy is stored.
+
+```Extra SSH options``` additional options appended to the SSH configuration. Can be used to customize the behavior of SSH connections.
+
+### Saving Changes
+
+Changes made in the settings page are saved by clicking the Save button. Some changes, like toggling SSH wildcard support,
+may trigger regeneration of SSH configurations.
+
+### Security considerations
+
+> ⚠️ **Attention:** Token authentication is required when TLS certificates are not configured.
