-## 0x Devnet
-
-A private, single-node PoA Ethereum network for testing purposes only. It uses
-Geth and the PoA implementation called "Clique".
-
-## Installation
-
-The devnet requires Docker to run (the latest version is recommended).
-
-In the package root directory, run:
-
-```
-docker build -t 0x-devnet .
-```
-
-## Usage
-
-To start the network, run:
-
-```
-docker run -it --rm -p 8501:8501 0x-devnet
-```
-
-Depending on your OS and how you installed docker, you may need to prefix any
-docker commands with `sudo`.
-
-The Docker container exposes the JSON RPC API at port 8501, and this is the
-primary way you are expected to interact with the devnet. The following
-endpoints are supported: `personal,db,eth,net,web3,txpool,miner,debug`.
-
-You can stop the network with `docker stop` and it will automatically clean up
-after itself. (`docker stop` typically requires you to use `docker ps` to find
-the name of the currently running container).
-
-### Configuration
-
-The devnet network only has a single node and uses PoA instead of PoW. That
-means that one node, called the "sealer", is the ultimate authority for
-validating transactions and adding new blocks to the chain. Since there is no
-PoW it also means that mining does not require significant computational
-resources. You can learn more about PoA and the Geth-specific implementation
-called "Clique" in [EIP-225](https://github.com/ethereum/EIPs/issues/225).
-
-The address of the "sealer" is `0xe8816898d851d5b61b7f950627d04d794c07ca37`. The
-password associated with the account is "password" and the (encrypted) private
-keys are visible in the **node0/keystore** directory. This account is already
-"unlocked" in the Geth node by default, so you can do things like sign and send
-transactions from this account using the JSON RPC endpoints directly.
-
-There are also a number of other addresses that have hard-coded starting
-balances for testing purposes. You can see the details in the **genesis.json**
-file. All of these accounts are also unlocked by default.
-
-### Additional JSON RPC Methods
-
-In addition to the
-[standard JSON RPC methods](https://github.com/ethereum/wiki/wiki/JSON-RPC) and
-the
-[Geth Management API](https://github.com/ethereum/go-ethereum/wiki/Management-APIs)
-The devnet node supports some additional JSON RPC methods:
-
-#### debug_increaseTime
-
-Increases the timestamp of the next mined block.
-
-##### Parameters
-
-`Number` - The number of seconds by which to increase the time offset.
-
-##### Returns
-
-`Number` - The total number of seconds by which the time offset has been
-increased (this includes all calls to `debug_increaseTime`).
-
-##### Example
-
-```js
-// Request
-curl -X POST --data '{"jsonrpc":"2.0","method":"debug_increaseTime","params":[100],"id":67}'
-
-// Result
-{
- "id":67,
- "jsonrpc": "2.0",
- "result": "5000"
-}
-```
-
-### Mining
-
-The node will automatically (nearly instantly) mine a block whenever new
-transactions are added to the transaction pool. If there are no transactions in
-the pool, it will wait.
-
-To stop mining, use the
-[`miner.stop`](https://github.com/ethereum/go-ethereum/wiki/Management-APIs#miner_stop)
-method.
-
-To start mining again, you can use the
-[`miner.start`](https://github.com/ethereum/go-ethereum/wiki/Management-APIs#miner_start)
-JSON RPC method.
