-bch-js is included in this [gatsby-ipfs-template](https://github.com/Permissionless-Software-Foundation/gatsby-ipfs-template) for building uncensorable web apps that can interact with the blockchain.

-This is because the new IPFS class in bch-js uses the fs library for uploading files, which is not supported by Gatsby.
-
-We also provide [minimal-slp-wallet-web](https://www.npmjs.com/package/minimal-slp-wallet-web) as a basic Bitcoin Cash wallet with SLP support, for front end projects. bch-js is encapsulated inside the instantiation of the library Class.
+[This gist](https://gist.github.com/christroutner/6cb9d1b615f3f9363af79723157bc434) shows how to include minimal-slp-wallet into a basic web page without using a framework.
