 In case you prefer using Docker:
 
-    sudo docker run -e DATABASE_TYPE=sqlite \
-               -p 80:80 -p 3030:3030 -p 5232:5232 \
-               -v /var/tracim/etc:/etc/tracim -v /var/tracim/var:/var/tracim algoo/tracim
+You need to install docker on your server first (see [here for debian](https://docs.docker.com/install/linux/docker-ce/debian/) or [here for windows]([docker toolbox](https://docs.docker.com/toolbox/toolbox_install_windows/)))
+
+Make sure `docker.service` is started correctly.
+
+    systemctl status docker.service
+
+Then use image like following (adapt volume paths or ports as you want):
+
+    sudo docker run \
+        -e DATABASE_TYPE=sqlite \
+        -p 80:80 \
+        -p 3030:3030 \
+        -p 5232:5232 \
+        -v /var/tracim/etc:/etc/tracim \
+        -v /var/tracim/var:/var/tracim \
+        algoo/tracim  # docker image: tracim:unstable for development version, tracim_test:latest for nightly builds
+
+
+All docker images are available here : https://hub.docker.com/u/algoo/
+More information about build docker image: https://github.com/tracim/docker_tracim
+
+Description of versioning:
+
+* algoo/`tracim:latest` is latest stable image from branch master
+* algoo/`tracim:<$tag>` is a stable tag image from branch master

 ### Installation ###
 
-Install `Apache` server and its [`WSGI` module](https://github.com/GrahamDumpleton/mod_wsgi):
+Install `tracim` first.
+Install `Apache` server and uwsgi  its [`WSGI` module](https://github.com/GrahamDumpleton/mod_wsgi):
 
-    sudo apt install apache2 libapache2-mod-wsgi-py3
+    sudo apt install apache2 libapache2-mod-wsgi-py3 uwsgi uwsgi-plugin-python3
 
 ### Configuration ###
 
 Create a file named `/etc/apache2/sites-available/tracim.conf` containing:

-Replace `[tracim_path]` and `[your_user]` above by your tracim installation path and your user.
+Enable this configuration file:
+
+    sudo ln -s /etc/apache2/sites-available/tracim.conf /etc/apache2/sites-enabled/
+
+Check if you just have `tracim.conf` in `/etc/apache2/sites-enabled`, if not, remove other file.
+
+
+Create the file named `/etc/uwsgi/apps-available/tracim.ini` containing:
+
+    [uwsgi]
+    plugins = python3
+    chdir = [tracim_path]/tracim
+    home = [tracim_path]/tg2env
+    wsgi-file = app.wsgi
+    callable = application
+    http-socket = 0.0.0.0:8080
+    enable-threads = true
+    env = PYTHON_EGG_CACHE=/tmp
+
+Replace [tracim_path] by your path of tracim
 
-Set the `APP_CONFIG` variable of the `tracim/app.wsgi` file to match your tracim installation path:
+Enable this configuration file:
+
+    sudo ln -s /etc/uwsgi/apps-available/tracim.ini /etc/uwsgi/apps-enabled/
+
+
+Create file `tracim.log` in `/var/log/uwsgi/app/`
+
+Set the `APP_CONFIG` variable of the `[tracim_path]/tracim/app.wsgi` file to match your tracim installation path:
 
     # -*- coding: utf-8 -*-
 
-    APP_CONFIG = "[tracim_path]/tracim/development.ini"
+    APP_CONFIG = "[tracim_path]/tracim/development.ini" 
+    #(in file: replace /var/www/tracim by your [tracim_path] )
 
     #Setup logging
     # import logging
     application = loadapp('config:%s' % APP_CONFIG)
     application.debug = False
 
+
+Add `webdav` at `root_path` in the `[tracim_path]/tracim/wsgidav.conf`:
+
+    ################################################################################
+    # Sample WsgiDAV configuration file
+    #
+    # 1. Rename this file to `wsgidav.conf`
+    # 2. Adjust settings as appropriate
+    # 3. Run tracim as you always do :)
+    #
+    ################################################################################
+    
+    ################################################################################
+    # SERVER OPTIONS
+    #===============================================================================

+    host  = "0.0.0.0"
+    
+    port = 3030
+    
+    show_history = True
+    show_deleted = True
+    show_archived = True
+    
+    manager_locks = True
+    
+    root_path = ''
+    
+    #===============================================================================
+    # Lock Manager
+    #
+    # Example: Use PERSISTENT shelve based lock manager
+    #from wsgidav.lock_storage import LockStorageShelve
+    #locksmanager = LockStorageShelve("wsgidav-locks.shelve")
+
+
+
+Open `[tracim_path]/tracim/development.ini` and make some change:
+
+
+    In [server:main] modify IP:
+    `host = 127.0.0.1` by `host = 0.0.0.0`
+
+    For Radical (CalDav server):
+    Uncomment `# radicale.server.host = 0.0.0.0`
+    Uncomment `# radicale.server.allow_origin = *`
+    Uncomment `# radicale.client.base_url.host = http://127.0.0.1:5232`
+    and modifiy IP `# radicale.client.base_url.host = http://127.0.0.1:5232`to `radicale.client.base_url.host = http://[Your_server_IP]:5232`
+    
+    For WSGIDAV
+    Uncomment `# wsgidav.client.base_url = 127.0.0.1:<WSGIDAV_PORT>`
+    and modify IP and PORT `# wsgidav.client.base_url = 127.0.0.1:<WSGIDAV_PORT>` to `wsgidav.client.base_url = [Your_server_IP]/webdav`
+
+
+Restart `uwsgi` configuration:
+
+    sudo systemctl restart uwsgi.service
+
 Load needed proxy modules and enable this site configuration file:
 
-    sudo a2enmod proxy proxy_http
+    sudo a2enmod dav_fs dav proxy proxy_http
     sudo a2ensite tracim.conf
 
-Reload `Apache` configuration:
+Restart `Apache` configuration:
 
-    sudo systemctl reload apache2.service
+    sudo systemctl restart apache2.service
+    
+**Important**
+In case you have some permission problem, check if `www-data` can access to folder of tracim.
