=== ``zettelstore run``
This starts the web service.

```
zettelstore run [-a PORT] [-c CONFIGFILE] [-d DIR] [-debug] [-p PORT] [-r] [-v]
```

; [!a|''-a PORT'']
: Specifies the TCP port through which you can reach the [[administrator console|00001004100000]].
  See the explanation of [[''admin-port''|00001004010000#admin-port]] for more details.
; [!c|''-c CONFIGFILE'']
: Specifies ''CONFIGFILE'' as a file, where [[startup configuration data|00001004010000]] is read.
  It is ignored if the given file is not available or not readable.

  Default: tries to read the following files in the ""current directory"": ''zettelstore.cfg'', ''zsconfig.txt'', ''zscfg.txt'', ''_zscfg'', and ''.zscfg''.
; [!d|''-d DIR'']
: Specifies ''DIR'' as the directory that contains all zettel.

  Default is ''./zettel'' (''.\\zettel'' on Windows), where ''.'' denotes the ""current directory"".
; [!debug|''-debug'']
: Allows debugging of the internal web server.
  Same as setting [[''debug-mode''|00001004010000#debug-mode]] to ""true"".

; [!p|''-p PORT'']
: Specifies the integer value ''PORT'' as the TCP port, where the Zettelstore web server listens for requests.

  Default: 23123.

  Zettelstore listens only on ''127.0.0.1'', e.g. only requests from the current computer will be processed.
  If you want to listen on a specific network interface to process requests from other computers, please use [[''listen-addr''|00001004010000#listen-addr]] of the configuration file.
; [!r|''-r'']
: Puts the Zettelstore in read-only mode.
  No changes are possible via the [[web user interface|00001014000000]] / via the [[API|00001012000000]].

  This allows to publish your content without any risks of unauthorized changes.
; [!v|''-v'']
: Be more verbose when writing logs.

Command line options take precedence over [[configuration file|00001004010000]] options.
