+You may want to delegate the work **Lotus Storage Miner** or **Lotus Node** perform to other machines. Here is how to setup the necessary authorization and environment variables.
+
+## Generate a JWT
+
+To generate a JWT for your environment variables, use this command:
+
+```sh
+lotus auth create-token --perm admin

+
+## Environment variables
+
+Environmental variables are variables that are defined for the current shell and are inherited by any child shells or processes. Environmental variables are used to pass information into processes that are spawned from the shell.
+
+Using the JWT you generated, you can assign it and the **multiaddr** to the appropriate environment variable.
+
+```sh
+# Lotus Node
+FULLNODE_API_INFO="JWT_TOKEN:/ip4/127.0.0.1/tcp/1234/http"
+
+# Lotus Storage Miner
+STORAGE_API_INFO="JWT_TOKEN:/ip4/127.0.0.1/tcp/2345/http"
+```
+
+* The **Lotus Node**'s `mutliaddr` is in `~/.lotus/api`.
+* The default token is in `~/.lotus/token`.
+* The **Lotus Storage Miner**'s `multiaddr` is in `~/.lotusstorage/config`.

-# Mining Hardware
+# Protocol Labs Standard Testing Configuration
 
-> This page is a work in progress. EVERYTHING HERE CAN CHANGE AND WILL CHANGE. PURCHASE HARDWARE AT YOUR OWN RISK.
+> This documentation page describes the standard testing configuration the Protocol Labs team has used to test **Lotus Storage Miner**s on Lotus. There is no guarantee this testing configuration will be suitable for Filecoin storage mining at MainNet launch. If you need to buy new hardware to join the Filecoin TestNet, we recommend to buy no more hardware than you require for testing. To learn more please read this [Protocol Labs Standard Testing Configuration post](https://filecoin.io/blog/filecoin-testnet-mining/).
 
-Please check out this [GitHub issue](https://github.com/filecoin-project/lotus/issues/694) to see benchmarks from existing hardware setups if you plan on participating in the **Filecoin TestNet**
+**Sector sizes** and **minimum pledged storage** required to mine blocks are two very important Filecoin TestNet parameters that impact hardware decisions. We will continue to refine all parameters during TestNet. 
+
+BECAUSE OF THIS, OUR STANDARD TESTING CONFIGURATION FOR FILECOIN MAINNET CAN AND WILL CHANGE. YOU HAVE BEEN WARNED.
+
+## Example configuration
+
+The setup below is a minimal example for sealing 32 GiB sectors on Lotus:
+
+* 2 TB of hard drive space.
+* 8 core CPU
+* 128 GiB of RAM
+
+## TestNet discoveries
+
+* If you only have 128GiB of ram, enabling 256GB of **NVMe** swap on an SSD will help you avoid out-of-memory issues while mining.
+
+## Benchmarked GPUs
+
+GPUs are a must for getting **block rewards**. Here are a few that have been confirmed to generate **SNARKs** quickly enough to successfully mine blocks on the Lotus TestNet.
+
+* GeForce RTX 2080 Ti
+* GeForce RTX 2080 SUPER
+* GeForce RTX 2080
+* GeForce GTX 1080 Ti
+* GeForce GTX 1080
+* GeForce GTX 1060
+
+## Testing other GPUs
+
+If you want to test a GPU that is not explicitly supported, you can use the following configuration flag:
+
+```sh
+BELLMAN_CUSTOM_GPU="<NAME>:<NUMBER_OF_CORES>"
+```
+
+Here is an example of trying a GeForce GTX 1660 ti with 1536 cores.
+
+```sh
+BELLMAN_CUSTOM_GPU="GeForce GTX 1660 Ti:1536"
+```
+
+To get the number of cores for your GPU, you will need to check your card’s specifications.
+
+## Benchmarking
+
+Here is a [benchmarking tool](https://github.com/filecoin-project/lotus/tree/testnet-staging/cmd/lotus-bench) and a [GitHub issue thread](https://github.com/filecoin-project/lotus/issues/694) for those who wish to experiment with and contribute hardware setups for the **Filecoin TestNet**.

 # Mining Troubleshooting
 
+## Bellman Lockfile
+
+The **Bellman** lockfile is created to lock a GPU for a process. This bug can occur when this file isn't properly cleaned up:
+
+```sh
+mining block failed: computing election proof: github.com/filecoin-project/lotus/miner.(*Miner).mineOne
+```
+
+This bug occurs when the storage miner can't acquire the `bellman.lock`. To fix it you need to stop the `lotus-storage-miner` and remove `/tmp/bellman.lock`.
