 The platform is composed of multiple Rust crates. Top-level executable binary crates include:

-* nym-mixnode - shuffles [Sphinx](https://github.com/nymtech/sphinx) packets together to provide privacy against network-level attackers.
-* nym-client - an executable which you can build into your own applications. Use it for interacting with Nym nodes.
-* nym-socks5-client - a Socks5 proxy you can run on your machine and use with existing applications.
-* nym-gateway - acts sort of like a mailbox for mixnet messages, which removes the need for direct delivery to potentially offline or firewalled devices.
-* nym-network-monitor - sends packets through the full system to check that they are working as expected, and stores node uptime histories as the basis of a rewards system ("mixmining" or "proof-of-mixing").
-* nym-explorer - a (projected) block explorer and (existing) mixnet viewer.
-* nym-wallet - a desktop wallet implemented using the [Tauri](https://tauri.studio/en/docs/about/intro) framework.
+* `nym-node` - a tool for running a node within the Nym network. Nym Nodes containing functionality such as `mixnode`, `entry-gateway` and `exit-gateway` are fundamental components of Nym Mixnet architecture. Nym Nodes are ran by decentralised node operators. Read more about `nym-node` in [Operators Guide documentation](https://nymtech.net/operators/nodes/nym-node.html). Network functionality of `nym-node` (labeled with `--mode` flag) can be:
+	- `mixnode` - shuffles [Sphinx](https://github.com/nymtech/sphinx) packets together to provide privacy against network-level attackers.
+	- `gateway` - acts sort of like a mailbox for mixnet messages, which removes the need for direct delivery to potentially offline or firewalled devices. Gateways can be further categorized as `entry-gateway` and `exit-gateway`. The latter has an extra embedded IP packet router and Network requester to route data to the internet.
+* `nym-client` - an executable which you can build into your own applications. Use it for interacting with Nym nodes.

 ### Building

-Platform build instructions are available on [our docs site](https://nymtech.net/docs/binaries/pre-built-binaries.html).
-Wallet build instructions are also available on [our docs site](https://nymtech.net/docs/wallet/desktop-wallet.html).

 ### Developing

-There's a `.env.sample-dev` file provided which you can rename to `.env` if you want convenient logging, backtrace, or other environment variables pre-set. The `.env` file is ignored so you don't need to worry about checking it in.
+There's a [`sandbox.env`](https://github.com/nymtech/nym/envs/sandbox.env) file provided which you can rename to `.env` if you want convenient testing environment. Read more about sandbox environment in our [Operators Guide page](https://nymtech.net/operators/sandbox.html).

-### Rewards
+### Tokenomics & Rewards

-Node, node operator and delegator rewards are determined according to the principles laid out in the section 6 of [Nym Whitepaper](https://nymtech.net/nym-whitepaper.pdf). Below is a TLDR of the variables and formulas involved in calculating the epoch rewards. Initial reward pool is set to 250 million Nym, making the circulating supply 750 million Nym.
