Prepare a crowdsale contract for an already ready token

I want to create a crowdsale contract. Here is the token contract I created on the testnet:

I want to create a separate crowdsale contract for the above token, but I tried 100s for 2 days, unfortunately it failed.

Have you managed to implement de crowdsale contract ? I find myself in the same situation...just have no idea what code to use :slight_smile:

Hi, welcome! :wave:

I have answered your question in another topic, you can have a check!

There is a simple example in the forum: 
https://forum.openzeppelin.com/t/help-me-write-an-erc20-token-and-a-crowdsale-contract/1797/2

Crowdsales are in OpenZeppelin Contracts 2.x (they were removed in 3.x). 
The documentation is here: https://docs.openzeppelin.com/contracts/2.x/crowdsales
