-## Running the simulator
-
-There are 3 ways to get the simulator up and running:
-
-1. Using [the version hosted on heroku](https://logic-gate-simulator.herokuapp.com/):
-
-This is by far the fastest solution - everything you need to do is open
-[the github-pages url](https://logic-gate-simulator.herokuapp.com/)
-
-2. Using a development server:
-
-First you need to have [node.js & npm](https://nodejs.org/en/download/) and [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) installed on your machine.
-
-Open a terminal in the desired folder and run:
-
-```sh
-#  Clone repo
-git clone https://github.com/Mateiadrielrafael/logicGateSimulator
-
-# Cd into the folder
-cd logicGateSimulator
-
-# install dependencies
-npm install
-
-# run development server
-npm run dev
-```
-
-3. Building the simulation yourself
-
-First, clone the repo and install the dependencies as explained in option 2.
-
-To build the source run:
-
-```sh
-# build program
-npm run build
-```
-
-To then run the simulation, open a server in the dist directory. A simple solution using npm:
-
-```sh
-# instal nano-server globally
-npm i nano-server -g
-
-# change directory
-cd dist
-
-# run server
-nano-server
-
-# linux
-open http://localhost:5000
-
-# Windows
-start http://localhost:5000
-```
-
-## Building a 4 - bit adder:
-
-1. Create a new ic called `half-adder` (`Create simulation` > `Integrated circuit` > `Half adder`)
-
-2. Add the following logic gates (`Logic gates` > the name of the gate):
-    - 2 buttons
-    - 2 light bulbs
-    - a XOR gate
-    - an AND gate
-
-> You can get more info about these gates by clicking `Logic gates` > the <i class='material-icons'>info</i> icon at the rght of the gate.
-
-3. To move a gate, drag & drop it with the right mouse button. To connect 2 pins, click once on each. Build the following configuration:
-
-![Half adder](./assets/half-adder.png)
-
-3. Create a new ic called `full-adder` (See step 1)
-4. Add the following gates (See step 2):
-    - 3 buttons
-    - 2 light bulbs
-    - 2 half adders
-    - an OR gate
-
-5) Build the following configuration (See step 3):
-   ![Full adder](./assets/full-adder.png)
-
-6) Create a new project called `4-bit-adder` (`Create simulation` > `Project` > `4-bit-adder`)
-
-7) Add the following components (See step 2):
-
-    - 8 button
-    - 5 light bulbs
-    - 3 full adders
-    - 1 half adder
-
-8) Build the following configuration (See step 3):
-   ![4-bit-adder](./assets/4-bit-adder.png)
-
-9) Enjoy!
-   Congratiulations! You've made your first circuit! With this simulator at your dispossal, the possibilities are endless! Here are a few things you can try and create yourself: - A 4-bit substractor - A counter - Different latches - If you are confident in you skills, you can even make a full 4-bit processor!
