+About
+-----
+
+This is minimized official FreeSwitch docker container.
+Container designed to run on host network.
+Size of container decreased to 120MB (54MB compressed)
+Significantly increased security:
+1) removed all libs except libc, busybox, freeswitch and dependent libs.
+2) removed 'system' API command from vanila config
+3) updated FreeSwitch default SIP password to random value
+
+Used environment variables
+--------------------------
+
+1) ```SOUND_RATES``` - rates of sound files that must be downloaded and installed. Available values ```8000```, ```16000```, ```32000```, ```48000```. May defined multiply values using semicolon as delimiter. Example ```SOUND_RATES=8000:16000```;
+2) ```SOUND_TYPES``` - types of sound files that must be downloaded and installed. Available values music, ```en-us-callie```, ```ru-RU-elena```, ```en-ca-june```, ```fr-ca-june```, ```pt-BR-karina```, ```sv-se-jakob```, ```zh-cn-sinmei```, ```zh-hk-sinmei```. Example ```SOUND_TYPES=music:en-us-callie```;
+3) ```EPMD``` - start epmd daemon, useful when you use mod_erlang and mod_kazoo FreeSwitch modules. Available values ```true```, ```false```.
+
+Usage container
+---------------
+
+1) Creating volume for sound files. This may be skipped if you not use freeswitch MOH and other sound files.
+```sh
+docker volume create --name freeswitch-sounds 
+```
+
+2) Stating container
+```sh
+docker run --net=host --name freeswitch \
+           -e SOUND_RATES=8000:16000 \
+           -e SOUND_TYPES=music:en-us-callie \
+           -v freeswitch-sounds:/usr/share/freeswitch/sounds \
+           -v /etc/freeswitch/:/etc/freeswitch \
+           safarov/freeswitch
+```
+
+systemd unit file
+-----------------
+You can use this systemd unit file on your hosts.
+```sh
+$ cat /etc/systemd/system/freeswitch-docker.service
+[Unit]
+Description=freeswitch Container
+After=docker.service network-online.target
+Requires=docker.service
+
+
+[Service]
+Restart=always
+TimeoutStartSec=0
+#One ExecStart/ExecStop line to prevent hitting bugs in certain systemd versions
+ExecStart=/bin/sh -c 'docker rm -f freeswitch; \
+          docker run -t --net=host --name freeswitch \
+                 -e SOUND_RATES=8000:16000 \
+                 -e SOUND_TYPES=music:en-us-callie \
+                 -v freeswitch-sounds:/usr/share/freeswitch/sounds \
+                 -v /etc/kazoo/freeswitch/:/etc/freeswitch \
+                 freeswitch'
+ExecStop=-/bin/sh -c '/usr/bin/docker stop freeswitch; \
+          /usr/bin/docker rm -f freeswitch;'
+
+[Install]
+WantedBy=multi-user.target
+```
+Unit file can be placed to ```/etc/systemd/system/freeswitch-docker.service``` and enabled by command
+```sh
+systemd start freeswitch-docker.service
+systemd enable freeswitch-docker.service
+```
+
+.bashrc file
+------------
+To simplify freeswitch managment you can add alias for ```fs_cli``` to ```.bashrc``` file as example bellow.
+```sh
+alias fs_cli='docker exec -i -t freeswitch /usr/bin/fs_cli'
+```
+
+How to create custom container
+------------------------------
+This container created from scratch image by addiding required freeswitch files packaged to tar.gz archive.
+To create custom container:
+1) install required FreeSwitch packages. Now supported debian dist
+```sh
+apt-get install freeswitch-conf-vanilla
+```
+2) clone freeswitch repo
+```sh
+git clone https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse
+```
+3) execute ```make_min_archive.sh``` script
+```sh
+cd freeswitch/docker/base_image
+./make_min_archive.sh
+```
+4) build custom container
+```sh
+docker build -t freeswitch_custom .
+```
