@@ -277,192 +277,201 @@ scan-path::
         project-list. Default value: none. See also: cache-scanrc-ttl,
         project-list.
 
 section::
         The name of the current repository section - all repositories defined
         after this option will inherit the current section name. Default value:
         none.
 
 section-from-path::
         A number which, if specified before scan-path, specifies how many
         path elements from each repo path to use as a default section name.
         If negative, cgit will discard the specified number of path elements
         above the repo directory. Default value: 0.
 
 side-by-side-diffs::
         If set to "1" shows side-by-side diffs instead of unidiffs per
         default. Default value: "0".
 
 snapshots::
         Text which specifies the default set of snapshot formats generated by
         cgit. The value is a space-separated list of zero or more of the
         values "tar", "tar.gz", "tar.bz2" and "zip". Default value: none.
 
 source-filter::
         Specifies a command which will be invoked to format plaintext blobs
         in the tree view. The command will get the blob content on its STDIN
         and the name of the blob as its only command line argument. The STDOUT
         from the command will be included verbatim as the blob contents, i.e.
         this can be used to implement e.g. syntax highlighting. Default value:
         none.
 
 summary-branches::
         Specifies the number of branches to display in the repository "summary"
         view. Default value: "10".
 
 summary-log::
         Specifies the number of log entries to display in the repository
         "summary" view. Default value: "10".
 
 summary-tags::
         Specifies the number of tags to display in the repository "summary"
         view. Default value: "10".
 
 strict-export::
         Filename which, if specified, needs to be present within the repository
         for cgit to allow access to that repository. This can be used to emulate
         gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
         repositories to match those exported by git-daemon. This option MUST come
         before 'scan-path'.
 
 virtual-root::
         Url which, if specified, will be used as root for all cgit links. It
         will also cause cgit to generate 'virtual urls', i.e. urls like
         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
         value: none.
         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
         same kind of virtual urls, so this option will probably be deprecated.
 
 REPOSITORY SETTINGS
 -------------------
 repo.about-filter::
         Override the default about-filter. Default value: none. See also:
         "enable-filter-overrides".
 
 repo.clone-url::
         A list of space-separated urls which can be used to clone this repo.
         Default value: none.
 
 repo.commit-filter::
         Override the default commit-filter. Default value: none. See also:
         "enable-filter-overrides".
 
 repo.defbranch::
         The name of the default branch for this repository. If no such branch
         exists in the repository, the first branch name (when sorted) is used
         as default instead. Default value: "master".
 
 repo.desc::
         The value to show as repository description. Default value: none.
 
 repo.enable-log-filecount::
         A flag which can be used to disable the global setting
         `enable-log-filecount'. Default value: none.
 
 repo.enable-log-linecount::
         A flag which can be used to disable the global setting
         `enable-log-linecount'. Default value: none.
 
 repo.enable-remote-branches::
         Flag which, when set to "1", will make cgit display remote branches
         in the summary and refs views. Default value: <enable-remote-branches>.
 
 repo.enable-subject-links::
         A flag which can be used to override the global setting
         `enable-subject-links'. Default value: none.
 
+repo.logo::
+        Url which specifies the source of an image which will be used as a logo
+        on this repo's pages. Default value: global logo.
+
+repo.logo-link::
+        Url loaded when clicking on the cgit logo image. If unspecified the
+        calculated url of the repository index page will be used. Default
+        value: global logo-link.
+
 repo.max-stats::
         Override the default maximum statistics period. Valid values are equal
         to the values specified for the global "max-stats" setting. Default
         value: none.
 
 repo.name::
         The value to show as repository name. Default value: <repo.url>.
 
 repo.owner::
         A value used to identify the owner of the repository. Default value:
         none.
 
 repo.path::
         An absolute path to the repository directory. For non-bare repositories
         this is the .git-directory. Default value: none.
 
 repo.readme::
         A path (relative to <repo.path>) which specifies a file to include
         verbatim as the "About" page for this repo. You may also specify a
         git refspec by head or by hash by prepending the refspec followed by
         a colon. For example, "master:docs/readme.mkd" Default value: <readme>.
 
 repo.snapshots::
         A mask of allowed snapshot-formats for this repo, restricted by the
         "snapshots" global setting. Default value: <snapshots>.
 
 repo.section::
         Override the current section name for this repository. Default value:
         none.
 
 repo.source-filter::
         Override the default source-filter. Default value: none. See also:
         "enable-filter-overrides".
 
 repo.url::
         The relative url used to access the repository. This must be the first
         setting specified for each repo. Default value: none.
 
 
 REPOSITORY-SPECIFIC CGITRC FILE
 -------------------------------
 When the option "scan-path" is used to auto-discover git repositories, cgit
 will try to parse the file "cgitrc" within any found repository. Such a
 repo-specific config file may contain any of the repo-specific options
 described above, except "repo.url" and "repo.path". Additionally, the "filter"
 options are only acknowledged in repo-specific config files when
 "enable-filter-overrides" is set to "1".
 
 Note: the "repo." prefix is dropped from the option names in repo-specific
 config files, e.g. "repo.desc" becomes "desc".
