 for local development. For the guide pages to work, you also
 need a local clone of the `doc-base` repository.
 
+To generate the images for translation status, the GD extension

+To generate the translation status, you'll also need the English version
+of the documentation and whatever languages you want to generate data
+about.

 ```sh
+# Leave empty to do all languages, must include 'en' if any listed
+$ PHP_LANGS=""
 $ git clone https://github.com/php/web-doc.git
 $ git clone https://github.com/php/doc-base.git

-## Installation
-Requirements:
-- PHP 8
-- GD extension (for generating charts)
-- SQLite3
-
-1. Unpack a copy of JpGraph 4.3.4 into `/include/jpgraph/` ([here](http://jpgraph.net/download/download.php?p=1))
-2. Increase memory limit for PHP scripts to at least 32MB
-3. Fill in two configuration files
-- `build-ops.php.sample` (rename it to `build-ops.php`)
-- `@GITDIR@` - absolute path to dir where scripts will clone GIT repos to and then use them for generating data
-- `@SQLITEDIR@` - absolute path to `/sqlite/` directory
-- `build-ops.sample` (rename it to `build-ops` [no ext])
-- `@PHP@` - path to the PHP executable file
-- `@DOCWEB@` - absolute path to `/www/` directory
-- `@PHDDIR@` - absolute path to directory with PhD installed from Git master
-- `@SCRIPTSDIR@`- absolute path to `/scripts/` directory
-- `@SQLITEDIR@` - absolute path to `/sqlite/` directory
-- `@SRCDIR@` - path to the directory with PHP source code in GIT repo
-4. You need to run the scripts/populatedocs.sh to fetch all the required documentation for the site.
-5. You need to run the scripts/generation.sh to generate the database and graphs (Time of generation: 2.5009639263153 s)
-6. Configure the virtual host under Apache. Current suggested settings are:
-```
-<VirtualHost 127.0.0.1:80>
- ServerName doc.php.net
- ServerAdmin [email protected]
-
- DocumentRoot /path/to/docweb/www
-
- ErrorDocument 404 /error.php
- php_flag register_globals Off
- php_flag magic_quotes_gpc Off
- php_flag magic_quotes_runtime Off
-
- <Directory /path/to/docweb/www>
