+### Basic Requirements
+Operating System: **Ubuntu 18.04**. Later releases of Ubuntu may also be compatible with these instructions.
+
+Install/configure the following applications:
+* git ([install instructions](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git))
+  * Don't forget to correctly set your git credentials:
+```
+git config --global user.name "FirstName LastName"
+git config --global user.email "[email protected]"
+```
+* docker ([install instructions](https://docs.docker.com/install/linux/docker-ce/ubuntu/))
+  * Make sure you can run docker as a non-root user ([instructions](https://docs.docker.com/install/linux/linux-postinstall/)).
+    Note you will need to reboot your machine for the group changes (`groupadd`) to work.
+* docker-compose ([install instructions](https://docs.docker.com/compose/install/))
+
+
+### Setup
+
+Get the code and get set up:
+```bash
+git https://github.com/Vikas14Web/c51_sym.git
+cd c51_sym
+
+# Run 
+docker-compose up -d
+```
+
+### To bash into the main docker
+```bash
+docker-compose exec app bash
+```
+
+### Running Tests
+
+You may now run those scripts by using `composer csfix`, `composer cscheck` and `composer phpstan`!
+```
+csfix: this script will try to fix as many errors as possible
+cscheck: this script will checks potential errors in your code
+composer phpstan: PHPStan focuses on finding errors in your code without actually running it
+```
