+# Configure recipe
+
+### Installing
+
+```php
+// deploy.php
+
+require 'vendor/deployphp/recipes/recipes/configure.php';
+```
+
+### Configuration options
+
+Make `shared` directory and put configure template files to it.   
+Template file extension is `.tpl` and it is removed on filename of compiled files.   
+> Note: All configure files will be created with the same structure with template files.   
+> Eg:   
+> `shared/config/app.php.tpl` -> `shared/config/app.php`   
+> `shared/server/apache.conf.tpl` -> `shared/server/apache.conf`   
+
+### Tasks
+
+- `deploy:configure` compile configure files and upload to servers
+
+### Suggested Usage
+
+Since you should only once time create configure files before deployment, 
+the `deploy:configure` task should be executed right only once time at the first. 
+If environment variable is changed, you can use this task to re-create configure files.
