 40.Ss Build
 41Building
 42.Nm
 43requires a go compiler and libsqlite.
 44On
 45.Ox
 46this is the go and sqlite3 packages.
 47Other platforms may require additional development libraries or headers
 48to be installed.
 49Run make.
 50Please be patient.
 51Even on fast machines, building from source can take several seconds.
 52.Ss Options
 53The following options control where
 54.Nm
 55looks for data.
 56.Bl -tag -width datadirx
 57.It Fl datadir
 58The root data directory, where the database and other user data are stored.
 59Requires write access.
 60Defaults to ".".
 61.It Fl viewdir
 62The root view directory, where html and other templates are stored.
 63Read only.
 64Defaults to ".".
 65.El
 66.Ss Init
 67Run the
 68.Ic init
 69command.
 70This will create the database and ask four questions, as well as creating
 71the initial user.
 72See below about importing existing data.
 73.Ss Operation
 74Run honk.
 75Log messages are sent to stderr and should probably be redirected to a file.
 76.Ss Customization
 77Add custom memes (stickers) to the
 78.Pa memes
 79data directory.
 80Image and video files are supported.
 81.Pp
 82Add custom emus (emoji) to the
 83.Pa emus
 84data directory.
 85Image files are supported.

 89file in the data directory.
 90A restart is required after changes.
 91.Pp
 92Custom HTML messages may be added to select pages by using the
 93.Ic admin
 94command.
 95A restart is required after changes.
 96.Bl -tag -width tenletters
 97.It server
 98Displayed on the home page.
 99.It about

105.Ss User Admin
106New users can be added with the

109This is discouraged.
110.Pp
111Passwords may be reset with the
112.Ic chpass Ar username
113command.
114.Ss Maintenance
115The database may grow large over time.
116The
117.Ic cleanup Op Ar days
118command exists to purge old data, by default 30 days.
119This removes unreferenced, unsaved posts and attachments.
120It does not remove any original content.
121.Ss Upgrade
122Stop the old honk process.
123Backup the database.
124Perform the upgrade with the
125.Ic upgrade
126command.
127Restart.
128.Pp
129There's also a
130.Pa blob.db
131file which is important to backup and restore.
132.Pp
133The current version of the honk binary may be printed with the
134.Ic version
135command.
136.Ss unplug
137Sometimes servers simply disappear, resulting in many errors trying to deliver
138undeliverable messages.
139Running
140.Ic unplug Ar hostname
141will delete all subscriptions and pending deliveries.
142.Ss Security
143.Nm

145Be mindful of what other services may be exposed via localhost or the
146local network.
147.Ss Debug
148Debug mode may be enabled or disabled by running
149.Ic debug Ar on|off .
150In debug mode, secure cookies are disabled and templates are reloaded
151every request.
152Debug mode is really more useful for development, not debugging production.
153.Ss Import
154Data may be imported and converted from other services using the
155.Ic import
156command.
157Posts are imported and backdated to appear as old honks.
158No other information is imported.
159.Pp
160Currently limited to Twitter import.
161This requires a Twitter data archive.
162After unzipping the data archive, navigate to the tweet_media directory
163and unzip any zip files contained within.
164.Dl ./honk import username twitter source-directory
165.Sh FILES
