+About
+-----
+
+Container designed to run on host, bridge and swarm network.
+Size of container decreased to 50MB (23MB compressed)
+Significantly increased security - removed all libs except libc, busybox, tcpdump, dumpcap, kamailio and dependent libs.
+Docker container is created useing Alpine linux packaging
+
+Used environment variables
+--------------------------
+
+1. ```SHM_MEMORY``` - amount of shared memory to allocate for the running Kamailio server (in Mb), default value 64Mb;
+2. ```PKG_MEMORY``` - amount of per-process (package) memory to allocate for Kamailio (in Mb), default value 8Mb
+
+Usage container
+---------------
+
+```sh
+docker run --net=host --name kamailio \
+           -v /etc/kamailio/:/etc/kamailio \
+           kamailio/kamailio
+```
+
+systemd unit file
+-----------------
+
+You can use this systemd unit files on your docker host.
+Unit file can be placed to ```/etc/systemd/system/kamailio-docker.service``` and enabled by commands
+```sh
+systemd start kamailio-docker.service
+systemd enable kamailio-docker.service
+```
+

+============
+
+```sh

+After=docker.service network-online.target
+Requires=docker.service
+
+
+[Service]
+Restart=always
+TimeoutStartSec=0

+          /usr/bin/docker rm -f kamailio;'
+
+[Install]
+WantedBy=multi-user.target
+```
+
+.bashrc file
+------------
+To simplify kamailio managment you can add alias for ```kamctl``` to ```.bashrc``` file as example bellow.
+```sh
+alias kamctl='docker exec -i -t kamailio /usr/sbin/kamctl'
