-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. When building a Gatsby (or other front-end app that uses Webpack), you'll need to add these lines to your `gatsby-node.js` file, as per [this issue](https://github.com/gatsbyjs/gatsby/issues/564):
+[minimal-slp-wallet](https://www.npmjs.com/package/minimal-slp-wallet) is a minimal wallet 'engine' that incorporates bch-js. It's compiled with Browserify for front end apps.

-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.

 ## Features

 - [ECMAScript 2017 standard JavaScript](https://en.wikipedia.org/wiki/ECMAScript#8th_Edition_-_ECMAScript_2017) used instead of TypeScript. Works
  natively with node.js v10 or higher.

- Full SLP tokens support: bch-js has full support for all SLP token functionality, including send, mint, and genesis transactions. It also fully support all aspects of [non-fugible tokans (NFTs)](https://www.youtube.com/watch?v=vvlpYUx6HRs).

+   * @apiName getTokenInfo
   * @apiGroup Transaction
   * @apiDescription
-   * Returns an object of transaction data, including addresses for input UTXOs.
-   * If it is a SLP token transaction, the token information for inputs and
-   * outputs will also be included.
+   * Given the TXID of a token transaction, it will return data about that
+   * token by retrieving the data from the Genesis transaction and docoding
+   * the OP_RETURN.
   *
-   * This is an API heavy call. This function will only work with a single txid.
-   * It does not yet support an array of TXIDs.
-   *
-   * This is the same as get(), except it omits DAG validation of the TXID.
   *
   * @apiExample Example usage:
   * (async () => {
   * try {
-   *  let txData = await bchjs.Transaction.get2("0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098");
