 You can configure Blocks using a configuration file. There are two possible locations and names for this file:
-  - In the home directory of the user account under which the server is run, named //PIXILAB-Blocks-config.yml//.

 === server: auth ===
-Specifies advanced authentication and authorization options. In most cases, you don't need to specify these settings. Use only when specifically instructed to do so, e.g. for integration with single-sign-on systems such as Active Directory or OKTA. Here's an [[https://int.pixilab.se/docs/blocks/sso/okta|example]] of how you can configure such options.
+Specifies advanced authentication and authorization options. The settings shown above correspond to the defaults if no auth section is provided. In most cases, you don't need to specify these settings. If you specify the //internalForm// authorization method, a "Log Out" command will be added to Blocks' Page menu, allowing you to explicitly log out.   The OidcClient setting allows for integration with single-sign-on systems such as [[blocks:sso:adfs|Active Directory]] or [[blocks:sso:okta|OKTA]].
+:!: **IMPORTANT**: While the //internalForm// method provides log-out functionality, it also sends all authoriztion credentials, including your password, as clear text. The default //internalDigest// method, while not providing any log-out functionality, avoids sending your password as clear text. When using Blocks on publicly accessible networks, you're strongly advised to use and only allow [[blocks:server:nginx|encrypted connection#https_domain_name_and_certificate]] (HTTPS) for all editing operations.
 ==== Top level tftp item ====

 See [[https://www.dropwizard.io/en/latest/manual/configuration.html#logging|here]] for more details on advanced logging. Those are advanced settings, that most users won't need. PIXILAB doesn't support servers where such advanced settings have been applied.
+==== Top level apiKeys item ====
-===== Alternative Blocks Data Location =====
+:!: **NOTE**: This feature was added in Blocks 6.1. If you're using an older version, this section does not apply to you.
+Lists a number of keys with their values:
+<code>
+apiKeys:
+  upload: "super-secret" # Value required as apiKey query parameter for uploads
+  customKey: "super-secret2"
+</code>
+The //upload// key's value (if specified) will be used by Blocks' [[blocks:api:upload|file upload API]]. When specified, all uploads must add an //apiKey// query parameter to their URL, with the value specified for the //upload// key.
+You can specify additional key/value pairs, as exemplified by the //customKey// key/value shown above. Such a key can then be applied to custom API endpoints decorated by @resource by also applying an @apiKey decorator, like this:
+<code>
+/* Receives a GET request such as:
+    http://<SERVER><:PORT-IF-REQUIRED>/rest/script/invoke/ScriptName/message/on/B
+   Exposing the trailing part (here "on/B") as the lastMessage property.
+ */
+@resource(undefined, 'GET')
+@apiKey("customKey") // Requires the query parameter apiKey=super-secret2
+public message(
+  body: object,    // Not used for GET requests (but must still be declared!)
+  trailer: string  // Trailing part of URL
+) {
+  this.lastMessage = trailer;
+  this.resetSoon();
+}
+</code>
+A function such as the one shown here must be placed in a User Script. For more information, see [[blocks:advanced_scripting#resource|this example]].
+:!: **IMPORTANT**: Unless you're using a secure (encrypted) server connection, //apiKey// query parameters are sent as clear text, and can be seen by anyone with access to your network. Learn more on how to use a secure (HTTPS) server connection [[blocks:server:nginx|here (if using our Linux based server image)]] or [[blocks:server:https|here]].
+==== Top level mqtt item ====
+:!: **NOTE**: This feature was added in Blocks 6.1. If you're using an older version, this section does not apply to you.
+<code>
+mqtt:
+  defaultBroker:
+    address: localhost  # Default is localhost
+    username: pixi   # Default is no username and password
+    password: pixi
+    encryption: false #Change to true if secure connection (tls) is available.
+</code>
+In the standard case, no explicit MQTT configuration is required, in which case a default broker connection to //localhost// with no username or password will be attempted. This is appropriate when using the MQTT broker included with our [[blocks:server:advanced_server_configuration:mqtt|Linux server image]] version 221214 and later.
+:!: **NOTE**: In addition to an MQTT broker, a suitable device driver is required for the device you want to control (here's an [[https://github.com/pixilab/blocks-script/blob/6.1/driver-archive/ShellySwitchGen1.ts|example MQTT driver]]).
+If you want to use a broker running on another computer, specify its IP address or name using the //address// setting as shown above. If your broker [[blocks:server:advanced_server_configuration:mqtt#security|requires authorization]] in order to connect, you must also specify the //username// and //password// options as ecpected by your broker's configuration.
+:!: **NOTE**: These are the credentials of your MQTT broker – not your Blocks server.
+===== Alternative Blocks Root Directory =====
 You can store Blocks' data somewhere else than in the “PIXILAB-Blocks-root” directory in the current user's home directory. This is done by putting a file named "PIXILAB-Blocks-config.yml" in the current user's home directory (option 1 of those mentioned at the top of this article). In this case, you must specify //root// in the configuration file:

 </code>
-If running your Blocks server on windows, the PIXILAB-Blocks-config.yml is still placed in the user home directory (C:\Users\[Your username]) and the path to the root directory should follow this structure:
+:!: **IMPORTANT note for servers based on our Linux server image version 221214 or later**: If you change the root path in the configuration file you must also change the corresponding //root// path under //location// under //server// in the file /etc/nginx/sites-available/blocks. You must be logged in as the //pixi-admin// user to edit that file and use //sudo// to edit the file (e.g., //sudo nano /etc/nginx/sites-available/blocks//), and finally restart nginx (or reboot the server).
+=== Windows Alternative Blocks Root Location ===
+If you're running Blocks server under Windows, the //PIXILAB-Blocks-config.yml// file is placed in the current user's home directory at //C:\Users\[Your username]//. The path to the desired Blocks root directory must be specified like this:
 <code>
 root: C:/External4/Blocks
 </code>
 This option tells Blocks to look for its data at the specified path, thus allowing you to put Blocks' data directory where you want. Additional options are specified in this "PIXILAB-Blocks-config.yml" file, as Blocks will //not// look in its data directory for any config.yml file.
