+# Requirements:
+a web server speaking PHP 8+, Composer and NPM to install dependencies.
+I develop on [Ubuntu](https://ubuntu.org), so here are the steps i recommend:
+
+ 
+## Install [Composer](https://getcomposer.org/download/) via PHP command
+Composer manages dependencies of a lot of php projects. Try these commands or refer to [the download docs of getcomposer.org](https://getcomposer.org/download/)
+``` 
+php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
+php -r "if (hash_file('sha384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
+php composer-setup.php
+php -r "unlink('composer-setup.php');"
+
+composer install
+```
+
+# Installation:
+When you have satisfied all the previous requirements you can install dependencies with [the bash script](/install.sh): 
+```bash
+bash install.sh
+```
+
+## Configure your app parameters
+In the [paramters.yml](/app/config/parameters.yml) file, setup your database access (create your DB if necessary). Works with mysql and others via the magic of Doctrine ORM.
+
+```yaml
+    database_host: 127.0.0.1
+    database_port: null
+    database_name: symfony
+    database_user: YOURDATABASEUSER
+    database_password: YOURDATABASEPASSWORD
+```
+
+update schema with doctrine in the command line.
+ ```bash
+php bin/console doctrine:schema:update --dump-sql
+php bin/console doctrine:schema:update --force
+```
+compile front end assets
+```bash
+yarn run encore dev --watch
+```
+
+access the front with your browser
+```bash
+php bin/console server:run
+firefox http://http://127.0.0.1:8000/
+```
+enjoy!
+
+#install via Docker ?
+I didn't do that for the moment, but you can contribute to this if you like to.
