-# Code conventions
-
-This document is about code pratices to be followed for any developer on Duniter.
-
-We enumerate here the conventions we try to follow *as much as possible* to have a robust and understandable code.
-
-## Rule 1: `let`, `const` and `var`
-
-`const` is the default variable declaration. Because most of the time we do not need to reassign a variable, so using `const` warns you if, by error, you try to reassign it. If reassignment was not an error and you do need to change the variable value, then modify `const` by `let` in this case.
-
-> We know, `const` is 5 characters and `let` is only 3. But these 2 more characters may be what makes the difference between robust and weak code.
-
-`var` is to be avoided, anytime. Prefer `const` or even `let`, everywhere.
-
-## Rule 2: `for` loops
-
-### `for (let i = .. ; .. ; ..)`
-
-As a consequence of rule 1, please avoid `var` for the `for` loop iterator variable. `const` cannot be used because the `i` iterator value is changed at each turn, so `let` is the only acceptable option for our code.
-
-### `for (.. of ..)`
-
-Prefer the `for(const value in array)` syntax instead of `for (.. in ..)` *if you don't need the array indices*. Indeed, not only do we save a line of code for value extraction (`const value = array[i]`), but `for(.. in ..)` iterates over *any enumerable property*, not only the array indices.
-
-So looking at these 2 examples, the first one `for(.. in ..)` will fail:
-
-```js
-const array1 = [1, 2, 3];
-array1.abc = 2;
-
-it('for (.. in ..)', () => {
-    let sum = 0;
-    for (const i in array1) {
-        sum += array1[i];
-    }
-    sum.should.equal(6); // <-- This test fails! sum equals 8, because we have an extra enumerable property `abc` which equals `2`.
-});
-
-it('for (.. of ..)', () => {
-    let sum = 0;
-    for (const value of array1) {
-        sum += value;
-    }
-    sum.should.equal(6); // <-- This test passes
-});
-```
-
-So, prefer using `for (.. of ..)` for array iteration, which has a built-in iterator taking care of iterating through indices only, or built-in functions like `forEach`, `map`, ... whenever possible.
-
-### Loops with promises in it
-
-When you have code in a loop dealing with promises, you *cannot* use `forEach`, `map`, ... built-in functions which takes a callback as argument. Only `for (let i = .. ; .. ; ..)` and `for (const value of ..)` syntax can be used to have executable code. The compiler will throw an error on parsing time (right before the program starts).
-
-> `for (.. in ..)` loops also works, but as we said earlier we do not use this syntax here.
-
-## Rule 3: always put braces
-
-Although JS do not care if you omit braces for a one line statement (for example in a `if`), **please add the embraces and adapted indentation anyway**. We prefer to see the explicit block of code concerned by a `if`. Example:
-
-```js
-if (a = 2) {
-    console.log('This is correct block');
-}
-```
-
-```js
-if (a = 2) console.log('This is INCORRECT block, it misses the braces');
-```
-
-## Use `Promise` API instead of `Q` library
-
-Whenever possible, please prefer native [JS Promise API](https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Promise). We used to use [Q API](https://github.com/kriskowal/q/wiki/API-Reference) while we were coding using ES5 JavaScript, but we may want to switch to faster promise library like [BlueBird](http://bluebirdjs.com/docs/getting-started.html).
-
-To reach this goal, we should avoid using Q specific API and use Promise instead. If we want in the future to change our Promise reference from native `Promise` to Bluebird (for example), we would just need to do the following:
-
-```js
-const Promise = require("bluebird");
-```
