Thanks @abcoathup! There are some good improvements here. I think the GSNBouncerERC20Fee section could use some restructuring of the content. I left some details in a comment below.

| The only thing you must do is extend from `GSNRecipient` and implement the accept method. | ||
| Depending on the logic for your Custom Bouncer, you may need to implement `_postRelayedCall` and `_preRelayedCall`. |

I think we should explain how the charge estimates work, and why they work that way: that pre will tell you the maximum possible charge, and later post will tell you the real amount. Or point towards GSNBouncerERC20Fee as an example of how to deal with it.

I have pointed to the GitHub repo 2.4.0 versions of GSNBouncerERC20Fee and GSNBouncerSignature. Is there a better way to do this?

I have updated the document based on my review.
I used request transactions rather than call, though the code uses call.
