 Summary: These are the steps to ensure the following builds don't have any diffs so that the firefox review goes smoothly.
 
-1. Run `yarn build`
-2. Run `yarn build:zip` - This will generate a `master-build.zip`, and `master-src.zip`.
-3. Move `master-src.zip`, and `master-build.zip` to its own enviornment/folder.

-5. Uncompress `master-build.zip` to `master-build`.
+1. Run `yarn build:ff` or `yarn build:chrome`, depending on your target browser.
+2. Run `yarn build:zip:ff` or `yarn build:zip:chrome` - This will generate a `master-<TARGET_BROWSER>-build.zip`, and `master-<TARGET_BROWSER>-src.zip`.

+4. Uncompress `master-<TARGET_BROWSER>-src.zip` to `master-src` and inside of `master-src` run `yarn && yarn build:<ff|chrome>`, depending on your target browser.
+5. Uncompress `master-<TARGET_BROWSER>-build.zip` to `master-build`.

 The actual in-depth technical breakdown is given in the next section for any dapp developer wishing to work with the raw objects injected into the window. However, convenience wrappers are provided that allows for any dapp to use this extension (or any other extension that conforms to the interface) without having to manage any additional info.
