 River's Proof of Reserves implementation in Elixir. This implementation is based on BitMEX's Proof of Reserves Python implementation, found [here](https://github.com/BitMEX/proof-of-reserves-liabilities).
 
-This library is used by River to generate its Proof of Liabilities tree and to allow users to download and verify the Proof of Liabilities.

+## Verifying River's Proof of Reserves
 
 This library comes with a `verify_liabilities.exs` script that will verify River's Proof of Reserves and the balances of any accounts you provide. The following steps will walk you through the process of verifying River's Proof of Reserves.
 
 ### 1. Fetch the Proof of Reserves Data
 
-Go to River's [Proof of Reserves](https://river.com/reserves) page. Log in with the email address you used to sign up for River.

 Click "Continue" and you will be prompted to run the setup script also seen in the next step.
 
 ### 2. Setup the Project
 
-In your terminal, run this command to clone the repository and install the dependencies. This step will install [asdf](https://asdf-vm.com/) and the Erlang/Elixir SDK.

-If you already have Erlang and Elixir installed or have already verified River's Proof of Reserves before, you can skip this step. If you have asdf installed but not Erlang/Elixir, you can install the SDK with asdf by running `asdf install` from this directory and skip this step.

 ```bash
 git clone https://github.com/RiverFinancial/proof-of-reserves.git
 cd proof-of-reserves

 ### 2. Run the Verification Script
 
-You will need to replace a few variables in the command below to run the script successfully. These values can be found in the River Proof of Reserves flow. If you followed the steps above, you will now see the command in the final screen. The command on the River page will already have your email and account string(s) filled in. You will need to fill in the `<CSV_PATH>` with the path to the CSV file you downloaded in Step 1.

 - `<EMAIL>` with the email address you used to sign up for River.
 - `<ACCOUNT_STRING>` in the format `<ACCOUNT_ID>:<ACCOUNT_KEY>`. If you have multiple accounts, you can provide this flag multiple times, like so: `--account <ACCOUNT_STRING_1> --account <ACCOUNT_STRING_2>`. You can find your account ID and key in the Proof of Reserves flow.
-- `<CSV_PATH>` with the path to the CSV file you downloaded in Step 1. The downloaded file will initially be zipped, so you will need to unzip it before providing the path to the CSV file.
