+Shared Hosting Environment
+==========================
+
+Shared hosting environments are often quite limited about configuration and directory structure. Still in most cases
+you can run Yii 2.0 on these.
+
+Deploying basic application
+---------------------------
+
+Since there's typically only one webroot it is recommended to use basic application template. Refer to
+[Installing Yii chapter](start-installation.md) and install application template locally.
+
+### Add extras for webserver
+
+If webserver used is Apache you'll need to add `.htacces` file with the following content to `web`
+(where `index.php` is):
+
+```
+Options +FollowSymLinks
+IndexIgnore */*
+
+RewriteEngine on
+
+# if a directory or a file exists, use it directly
+RewriteCond %{REQUEST_FILENAME} !-f
+RewriteCond %{REQUEST_FILENAME} !-d
+
+# otherwise forward it to index.php
+RewriteRule . index.php
+```
+
+In case of nginx you should not need any extra config files.
+
+### Renaming webroot
+
+If after connecting to your shared hosting via FTP or by other means you're seeing something like the following, you're
+most probably lucky.
+ 
+```
+config/
+logs/
+www/
+```
+
+In the above `www` is webserver directory root (i.e. webroot). It could be named differently. Common names are: `www`,
+`htdocs`, `public_html`. Since we have webroot in our basic application template named `web` we need to rename it to
+whatever hosting webroot is before uploading.
+
+### FTP root directory is writeable
+
+If you can write to the root level directory i.e. where `config`, `logs` and `www` are, just upload `assets`, `commands`
+etc. as is.
+
+### Check requirements
+
+In order to run Yii hosting should meet its requirements. The very minimum requirement is PHP 5.4. In order to check
+the rest copy `requirements.php` from root directory into webroot directory and run it via browser using
+`http://example.com/requirements.php` URL. Don't forget to delete the file afterwards.
+
+
+Deploying advanced application
+------------------------------
+
+Deploying advanced application to shared hosting is a bit trickier than doing it with basic application because it has
+two webroots.
