 The main branches under development at the moment are:
 * [`master`](https://github.com/filecoin-project/lotus): current testnet.
 * [`next`](https://github.com/filecoin-project/lotus/tree/next): working branch with chain-breaking changes.
 * [`ntwk-calibration`](https://github.com/filecoin-project/lotus/tree/ntwk-calibration): devnet running one of `next` commits.

+
+All work is tracked via issues. An attempt at keeping an up-to-date view on remaining work towards Mainnet launch can be seen at the [lotus github project board](https://github.com/orgs/filecoin-project/projects/8). The issues labeled with `incentives` are there to identify the issues needed for Space Race launch.

 ### `FIL_PROOFS_USE_GPU_COLUMN_BUILDER=1` Environment variable
 
 This env var can be used with `lotus-miner`, `lotus-worker`, and `lotus-bench` to enable experimental precommit2 GPU acceleration
+
+### Setting multiaddresses
+
+Set multiaddresses for the miner to listen on in a miner's `config.toml` file
+(by default, it is located at `~/.lotusminer/config.toml`). The `ListenAddresses` in this file should be interface listen addresses (usually `/ip4/0.0.0.0/tcp/PORT`), and the `AnnounceAddresses` should match the addresses being passed to `set-addrs`.
+
+The addresses passed to `set-addrs` parameter in the commands below should be currently active and dialable; confirm they are before entering them.
+
+Once the config file has been updated, set the on-chain record of the miner's listen addresses:
+
+ ```
+ lotus-miner actor set-addrs <multiaddr_1> <multiaddr_2> ... <multiaddr_n>
+```
+
+This updates the `MinerInfo` object in the miner's actor, which will be looked up
+when a client attempts to make a deal. Any number of addresses can be provided.
+
+Example:
+
+```
+ lotus-miner actor set-addrs /ip4/123.123.73.123/tcp/12345 /ip4/223.223.83.223/tcp/23456
