-### Webserver setup
-
-The `website/` directory in the build directory contains the configured
-website. Include the directory into your webbrowser to serve php files
-from there.
-
-#### Configure for use with Apache
-
-Make sure your Apache configuration contains the required permissions for the
-directory and create an alias:
+## Downloading and building Nominatim

 
 

-    <Directory "/srv/nominatim/build/website">
-      Options FollowSymLinks MultiViews
-      AddType text/html   .php
-      DirectoryIndex search.php
-      Require all granted
-    </Directory>
-    Alias /nominatim /srv/nominatim/build/website
+### Downloading the latest release

 
 

-`/srv/nominatim/build` should be replaced with the location of your
-build directory.
+You can download the [latest release from nominatim.org](https://nominatim.org/downloads/).
+The release contains all necessary files. Just unpack it.

 
 

-After making changes in the apache config you need to restart apache.
-The website should now be available on http://localhost/nominatim.
+### Downloading the latest development version

 
 

-#### Configure for use with Nginx
+If you want to install latest development version from github, make sure to
+also check out the osm2pgsql subproject:

 
 

-Use php-fpm as a deamon for serving PHP cgi. Install php-fpm together with nginx.
+```
+git clone --recursive git://github.com/openstreetmap/Nominatim.git
+```

 
 

-By default php listens on a network socket. If you want it to listen to a
-Unix socket instead, change the pool configuration (`pool.d/www.conf`) as
-follows:
+The development version does not include the country grid. Download it separately:

 
 

-    ; Comment out the tcp listener and add the unix socket
-    ;listen = 127.0.0.1:9000
-    listen = /var/run/php5-fpm.sock
+```
+wget -O Nominatim/data/country_osm_grid.sql.gz https://www.nominatim.org/data/country_grid.sql.gz
+```

 
 

-    ; Ensure that the daemon runs as the correct user
-    listen.owner = www-data
-    listen.group = www-data
-    listen.mode = 0666
+### Building Nominatim

 
 

-Tell nginx that php files are special and to fastcgi_pass to the php-fpm
-unix socket by adding the location definition to the default configuration.
+The code must be built in a separate directory. Create the directory and
+change into it.

 
 

-    root /srv/nominatim/build/website;
-    index search.php index.html;
-    location / {
-            try_files $uri $uri/ @php;
-    }
+```
+mkdir build
+cd build
+```

 
 

-    location @php {
-            fastcgi_param SCRIPT_FILENAME "$document_root$uri.php";
-            fastcgi_param PATH_TRANSLATED "$document_root$uri.php";
-            fastcgi_param QUERY_STRING    $args;
-            fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
-            fastcgi_index index.php;
-            include fastcgi_params;
-    }
+Nominatim uses cmake and make for building. Assuming that you have created the
+build at the same level as the Nominatim source directory run:

 
 

-    location ~ [^/]\.php(/|$) {
-        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
-        if (!-f $document_root$fastcgi_script_name) {
-            return 404;
-        }
-        fastcgi_pass unix:/var/run/php7.2-fpm.sock;
-        fastcgi_index search.php;
-        include fastcgi.conf;
-    }
+```
+cmake ../Nominatim
+make
+sudo make install
+```

 
 

-Restart the nginx and php5-fpm services and the website should now be available
-at `http://localhost/`.
+Nominatim installs itself into `/usr/local` per default. To choose a different
+installation directory add `-DCMAKE_INSTALL_PREFIX=<install root>` to the
+cmake command. Make sure that the `bin` directory is available in your path
+in that case, e.g.

 
 

+```
+export PATH=<install root>/bin:$PATH
