 28.Xr honk 1 .
 29.Ss Setup
 30.Pp
 31Set up a TLS reverse proxy.
 32.Nm

 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.
 86.Pp
 87Site CSS may be overridden by creating a
 88.Pa views/local.css
 89file in the data directory.
 90A restart is required after changes.

114.Ic chpass Ar username
115command.
116.Pp
117Users may be deleted with the
118.Ic deluser Ar username
119command.
120.Ss Maintenance
121The database may grow large over time.
122The
123.Ic cleanup Op Ar days
124command exists to purge old data, by default 30 days.
125This removes unreferenced, unsaved posts and attachments.
126It does not remove any original content.
127.Ss Upgrade
128Stop the old honk process.
129Backup the database.
130Perform the upgrade with the
131.Ic upgrade
132command.
133Restart.
134.Pp
135There's also a
136.Pa blob.db
137file which is important to backup and restore.
138.Pp
139The current version of the honk binary may be printed with the
140.Ic version
141command.
142.Ss unplug
143Sometimes servers simply disappear, resulting in many errors trying to deliver
144undeliverable messages.
145Running
146.Ic unplug Ar hostname
147will delete all subscriptions and pending deliveries.
148.Ss Security
149.Nm
150is not currently hardened against SSRF, server side request forgery.
151Be mindful of what other services may be exposed via localhost or the
152local network.
153.Ss Debug
154Debug mode may be enabled or disabled by running
155.Ic debug Ar on|off .
156In debug mode, secure cookies are disabled and templates are reloaded
157every request.
158Debug mode is really more useful for development, not debugging production.
159.Ss Import
160Data may be imported and converted from other services using the
161.Ic import
162command.
163Posts are imported and backdated to appear as old honks.
164No other information is imported.

172and unzip any zip files contained within.
173.Dl ./honk import username twitter source-directory
