+Introduction
+------------
+
+This is the continuation of the original Debian syslog daemon package
+by [Martin Schulze][], it implements two system log daemons:
+
+The `syslogd` daemon is an enhanced version of the standard Berkeley
+utility program.  It is responsible for providing logging of messages
+received from programs and facilities on the local host as well as from
+remote hosts.
+
+The `klogd` daemon listens to kernel message sources and is responsible
+for prioritizing and processing operating system messages.  The `klogd`
+daemon can run as a client of `syslogd` or optionally as a standalone
+program.  `klogd` can now be used to decode EIP addresses if it can
+determine a `System.map` file.
+
+Main differences from the original sysklogd are:
+
+- Built-in log-rotation support, useful for embedded systems.  No need
+  for cron and a separate logrotate daemon
+- FreeBSD socket receive buffer size patch
+- Avoid blocking `syslogd` if console is backed up
+- Touch PID file on `SIGHUP`, for integration with [Finit][]
+- Support for configuring remote syslog timeouot
+
+
+Build & Install
+---------------
+
+The GNU Configure & Build system use `/usr/local` as the default install
+prefix.  In many cases this is useful, but this means the configuration
+files and cache files will also use that same prefix.  Most users have
+come to expect those files in `/etc/` and `/var/run/` and configure has
+a few useful options that are recommended to use:
+
+    $ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
+    $ make -j5
+    $ sudo make install-strip
+
+You may want to remove the `--prefix=/usr` option.
+
+
+Building from GIT
+-----------------
+
+If you want to contribute, or just try out the latest but unreleased
+features, then you need to know a few things about the [GNU build
+system][buildsystem]:
+
+- `configure.ac` and a per-directory `Makefile.am` are key files
+- `configure` and `Makefile.in` are generated from `autogen.sh`,
+  they are not stored in GIT but automatically generated for the
+  release tarballs
+- `Makefile` is generated by `configure` script
+
+To build from GIT you first need to clone the repository and run the
+`autogen.sh` script.  This requires `automake` and `autoconf` to be
+installed on your system.
+
+    git clone https://github.com/troglobit/sysklogd.git
+    cd sysklogd/
+    ./autogen.sh
+    ./configure && make
+
+GIT sources are a moving target and are not recommended for production
+systems, unless you know what you are doing!
