Appwrite setup

Initial setup 🛠️

Creating an account on Appwrite Cloud.
Create a new project with any name you want and choose web as a platform.
- Name the web project anything you like and Set Hostname to localhost.
Copy .env.example file to .env.local and appwrite-gen/.env.example file to appwrite-gen/.env manually or using:
```
cp .env.example .env.local
cp appwrite-gen/.env.example appwrite-gen/.env
```
Go to settings and copy your project id and paste it in .env.local file as well as in appwrite-gen/.env files.
While on the settings page click on View API Keys button.
Create an API key with any name you like, set the scopes to all and copy it's value and paste it in appwrite-gen/.env file as PROJECT_API_KEY variable.
Setup your database with the command:
```
yarn schema:prepare
```
this should create a database with users, posts, etc. collections.
Fill in the rest of .env.local file with the appropriate ids if not already set.

Make changes through the appwrite console.
Generate the schema with the command:
```
yarn schema:generate
```
this should update appwrite-gen/schema.json with your changes.
Simply push this file through the git workflow mentioned here.
