## Overview
2+
3+
This script is designed to provide opportunity using the OpportunityProvider contract.
4+
5+
## Installation
6+
7+
### npm
8+
9+
```
10+
$ npm install
11+
```
12+
13+
## Quickstart
14+
15+
### Approve Tokens
16+
17+
To provide a new opportunity, first make sure that you approved your tokens for `Permit2` contract using the command below:
18+
19+
```
20+
# Approve Permit2 to use them
21+
cast send \
22+
--private-key $PRIVATE_KEY \
23+
--rpc-url $RPC_URL \
24+
$TOKEN \
25+
"approve(address spender, uint256 value)" \
26+
$PERMIT2 $AMOUNT
27+
```
28+
29+
### Provide Opportunity
30+
31+
Then update the `opportunity.json` and `config.json` files for the opportunity you want to provide, and then run the following command:
32+
33+
```
34+
$ npm run opportunity-provider
35+
```
