-## Adding a JS dependency
-In order to use a JS library (let's take Handlebars as an example), you need to follow these steps:
-
-* add "handlebars" as a dependency in the `package.json` file
-```json
-{
-  "private": true,
-  "dependencies": {
-    "handlebars": "3.0.3",
-  },
-```
-* run `./do install` (the handlebars module will be added into the node_modules folder)
-* create a symlink to the file you want to use by running this command
-```sh
-# from the root of the project
-$ cd assets/js/lib/
-# /!\ use relative path to the node_modules folder
-$ ln -nsf ../../../node_modules/handlebars/dist/handlebars.min.js handlebars.min.js
-```
-* make sure to push the symlink onto the repository
\ No newline at end of file
+- Classes can be no longer than 100 LOC.
+- Methods can be no longer than 5 LOC.
+- Pass no more than 4 parameters/hash keys into a method.
+- Routes can instantiate only one object.
