+<br />Only self compiled firmware may do not have a web-server sod if you use your own compiled firmware be aware to enable the web-server, otherwise you can only use the <code>--file</code> parameter as source.</li>
+</ul>
+<h2 id="file-types">File Types</h2>
+<p><em>decode-config.py</em> can handle the following backup file types:  </p>
+<h3 id="-dmp-format">.dmp Format</h3>
+<p>Configuration data as used by Tasmota &quot;Backup/Restore Configuration&quot; web interface.<br>This format is binary and encrypted.</p>
+<h3 id="-json-format">.json Format</h3>
+<p>Configuration data in <a href="http://www.json.org/">JSON</a>-format.<br>This format is decrypted, human readable and editable and can also be used for the <code>--restore-file</code> command.<br>This file will becreated by <em>decode-config.py</em> using <code>--backup-file</code> with <code>--backup-type json</code> parameter (default).</p>
+<h3 id="-bin-format">.bin Format</h3>
+<p>Configuration data in binary format.<br>This format is binary decryptet, editable (e.g. using a hex editor) and can also be used for <code>--restore-file</code> command.<br>It will be created by <em>decode-config.py</em> using <code>--backup-file</code> with <code>--backup-type bin</code>.<br>Note:<br>This file is 4 byte longer than an original .dmp file due to an prefix header at the beginning. The file data starting at address position 4 are containing the same as the <strong>struct SYSCFG</strong> from Tasmota <a href="https://github.com/arendst/Sonoff-Tasmota/blob/master/sonoff/settings.h">settings.h</a> in decrypted format.</p>
+<h4 id="file-extensions">File extensions</h4>
+<p><em>decode-config.py</em> uses auto extension as default for backup filenames; you don&#39;t need to append extensions to your backup file, it will be selected based on <code>--backup-type</code> argument.<br>If you want using your own extension use the <code>--no-extension</code> argument.</p>
+<h2 id="usage">Usage</h2>
+<p>After download don&#39;t forget to set exec flag under linux with <code>chmod +x decode-config.py</code> or call the program using <code>python decode-config.py...</code>.</p>
+<h3 id="basics">Basics</h3>
+<p>At least pass a source where you want to read the configuration data from using <code>-f &lt;filename&gt;</code> or <code>-d &lt;host&gt;</code>:</p>
+<p>The source can be either </p>
+<ul>
+<li>a Tasmota device hostname or IP by passing it using the <code>-d &lt;host&gt;</code> arg</li>
+<li>or a previously stored Tasmota *.dmp<code>configuration file by passing the filename using</code>-f <filename>` arg</li>
+</ul>
+<p>Example:  </p>
+<pre><code>decode-config<span class="hljs-selector-class">.py</span> -d sonoff-<span class="hljs-number">4281</span>
+</code></pre><p>will output a human readable configuration in <a href="http://www.json.org/">JSON</a>-format:</p>

+<h3 id="restore-backup-file">Restore backup file</h3>
+<p>Reading back a saved (and possible changed) backup file use the <code>--restore-file &lt;filename&gt;</code> arg. This will read the (changed) configuration data from this file and send it back to the source device or filename.</p>

+<p>If an argument is specified in more than one place, then commandline values override config file values which override defaults. This is usefull if you always use the same argument or a basic set of arguments.</p>
+<p>The http authentication credentials <code>--username</code> and <code>--password</code> is predestinated to store it in a file instead using it on your command line as argument:</p>
+<p>e.g. my.conf:</p>

+<span class="hljs-attr">username</span> = admin
+<span class="hljs-attr">password</span> = myPaszxwo!z

+
+## Prerequisite
+* [Python](https://en.wikipedia.org/wiki/Python_(programming_language))  
+  This program is written in [Python](https://en.wikipedia.org/wiki/Python_(programming_language)) so you need to install a python environment (for details see [Python Setup and Usage](https://docs.python.org/2.7/using/index.html))
+* [Sonoff-Tasmota](https://github.com/arendst/Sonoff-Tasmota) [Firmware](https://github.com/arendst/Sonoff-Tasmota/releases) with enabled Web-Server  
+  To backup or restore configurations from/to a Sonoff-Tasmota device you need a firmare with enabled web-server in admin mode (command [WebServer 2](https://github.com/arendst/Sonoff-Tasmota/wiki/Commands#wifi)).
+  <br />Only self compiled firmware may do not have a web-server sod if you use your own compiled firmware be aware to enable the web-server, otherwise you can only use the `--file` parameter as source.
+
+## File Types
+_decode-config.py_ can handle the following backup file types:  
+### .dmp Format
+Configuration data as used by Tasmota "Backup/Restore Configuration" web interface.  
+This format is binary and encrypted.
+### .json Format
+Configuration data in [JSON](http://www.json.org/)-format.  
+This format is decrypted, human readable and editable and can also be used for the `--restore-file` command.  
+This file will becreated by _decode-config.py_ using `--backup-file` with `--backup-type json` parameter (default).
+### .bin Format
+Configuration data in binary format.  
+This format is binary decryptet, editable (e.g. using a hex editor) and can also be used for `--restore-file` command.  
+It will be created by _decode-config.py_ using `--backup-file` with `--backup-type bin`.  
+Note:  
+This file is 4 byte longer than an original .dmp file due to an prefix header at the beginning. The file data starting at address position 4 are containing the same as the **struct SYSCFG** from Tasmota [settings.h](https://github.com/arendst/Sonoff-Tasmota/blob/master/sonoff/settings.h) in decrypted format.
+
+#### File extensions
+_decode-config.py_ uses auto extension as default for backup filenames; you don't need to append extensions to your backup file, it will be selected based on `--backup-type` argument.  
+If you want using your own extension use the `--no-extension` argument.
+
+## Usage
+After download don't forget to set exec flag under linux with `chmod +x decode-config.py` or call the program using `python decode-config.py...`.
+
+### Basics
+At least pass a source where you want to read the configuration data from using `-f <filename>` or `-d <host>`:
+
+The source can be either 
+* a Tasmota device hostname or IP by passing it using the `-d <host>` arg
+* or a previously stored Tasmota *.dmp` configuration file by passing the filename using `-f <filename>` arg
+
+Example:  
+
+    decode-config.py -d sonoff-4281
+
+will output a human readable configuration in [JSON](http://www.json.org/)-format:
+
+    {
+      "altitude": 112, 
+      "baudrate": 115200, 
+      "blinkcount": 10, 
+      "blinktime": 10, 
+    ...
+      "ws_width": [
+        1, 
+        3, 
+        5
+      ]
+    }
+
+
+### Save backup file
+To save the output as backup file `--backup-file <filename>`, you can use placeholder for Version, Friendlyname and Hostname:  
+
+    decode-config.py -d sonoff-4281 --backup-file Config_@f_@v
+    
+If you have setup a WebPassword within Tasmota, use
+
+    decode-config.py -d sonoff-4281 -p <yourpassword> --backup-file Config_@f_@v
+
+will create a file like `Config_Sonoff_x.x.x.json`. Because it is in JSON format, you can read and edit the file with any raw text editor.
+
+### Restore backup file
+Reading back a saved (and possible changed) backup file use the `--restore-file <filename>` arg. This will read the (changed) configuration data from this file and send it back to the source device or filename.
+
+To restore the previously save backup file `Config_Sonoff_6.2.1.json` to device `sonoff-4281` use:  
+
+    decode-config.py -d sonoff-4281 --restore-file Config_Sonoff_6.2.1.json
+    
+with password set by WebPassword:
+
+    decode-config.py -d sonoff-4281 -p <yourpassword> --restore-file Config_Sonoff_6.2.1.json
+
+### Configuration file
+Each argument that start with `--` (eg. `--file`) can also be set in a config file (specified via -c). Config file syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax at [https://pypi.org/project/ConfigArgParse](https://pypi.org/project/ConfigArgParse/)).
+
+If an argument is specified in more than one place, then commandline values override config file values which override defaults. This is usefull if you always use the same argument or a basic set of arguments.
+
+The http authentication credentials `--username` and `--password` is predestinated to store it in a file instead using it on your command line as argument:
+
+e.g. my.conf:
+
+    [source]
+    username = admin
+    password = myPaszxwo!z
+
+To make a backup file from example above you can now pass the config file instead using the password on command line:
+
+    decode-config.py -d sonoff-4281 -c my.conf --backup-file Config_@f_@v
+
+
+
+### More program arguments
+For better reading your porgram arguments each short written arg (minus sign `-`) has a corresponding readable long version (two minus signs `--`), eg. `--device` for `-d` or `--file` for `-f` (note: not even all `--` arg has a corresponding `-` one).
+
+A short list of possible program args is displayed using `-h` or `--help`.
+
+For advanced help use `-H` or `--full-help`:
+
+    usage: decode-config.py [-f <filename>] [-d <host>] [-P <port>]
+                            [-u <username>] [-p <password>] [-i <filename>]
+                            [-o <filename>] [-F json|bin|dmp] [-E] [-e]
+                            [--json-indent <indent>] [--json-compact]
+                            [--json-hide-pw] [--json-unhide-pw] [-h] [-H] [-v]
+                            [-V] [-c <filename>] [--ignore-warnings]
+
+    Backup/Restore Sonoff-Tasmota configuration data. Args that start with '--'
+    (eg. -f) can also be set in a config file (specified via -c). Config file
+    syntax allows: key=value, flag=true, stuff=[a,b,c] (for details, see syntax at
+    https://goo.gl/R74nmi). If an arg is specified in more than one place, then
+    commandline values override config file values which override defaults.
+
+    optional arguments:
+      -c, --config <filename>
+                            program config file - can be used to set default
+                            command args (default: None)
+      --ignore-warnings     do not exit on warnings. Not recommended, used by your
+                            own responsibility!

+### Examples
+The most of the examples are for linux command line. Under Windows call the program using `python decode-config.py ...`.
+
+#### Config file
+Note: The example contains .ini style sections `[...]`. Sections are always treated as comment and serves as clarity only.
+For further details of config file syntax see [https://pypi.org/project/ConfigArgParse](https://pypi.org/project/ConfigArgParse/).
+
+*my.conf*
+
+    [Source]
+    username = admin
+    password = myPaszxwo!z
+
+    [JSON]
+    json-indent 2
+
+#### Using Tasmota binary configuration files
+
+1. Restore a Tasmota configuration file
+
+    `decode-config.py -c my.conf -d sonoff --restore-file Config_Sonoff_6.2.1.dmp`
+
+2. Backup device using Tasmota configuration compatible format
+
+   a) use file extension to choice the file format
+
+    `decode-config.py -c my.conf -d sonoff --backup-file Config_@f_@v.dmp`
+
+   b) use args to choice the file format
+
+    `decode-config.py -c my.conf -d sonoff --backup-type dmp --backup-file Config_@f_@v`
+
+#### Use batch processing
+
+    for device in sonoff1 sonoff2 sonoff3; do ./decode-config.py -c my.conf -d $device -o Config_@f_@v
+
+or under windows
+
+    for device in (sonoff1 sonoff2 sonoff3) do python decode-config.py -c my.conf -d %device -o Config_@f_@v
+
+will produce JSON configuration files for host sonoff1, sonoff2 and sonoff3 using friendly name and Tasmota firmware version for backup filenames.
