+# Setting up a Single Node Neutron Testnet
+
+This guide provides instructions for setting up a single node Neutron testnet using Docker and local installation.
+
+> Note - For more detailed instructions, refer to the [official Neutron documentation](https://docs.neutron.org/neutron/build-and-run/neutron-docker).
+
+## Setup Steps
+
+Clone the Neutron repository in your `$HOME` or your preferred repository:
+```
+git clone -b v4.0.1 https://github.com/neutron-org/neutron.git
+cd neutron
+```
+
+Build the Docker image:
+```
+make build-docker-image
+```
+
+Start the Docker container:
+```
+make start-docker-container
+```
+
+Monitor the logs:
+```
+docker ps  # Get the container ID
+docker logs -f <neutron-node-container-id>
+```
+
+Verify the Docker keyring setup:
+```
+docker exec -it neutron neutrond query bank balances neutron1qnk2n4nlkpw9xfqntladh74w6ujtulwn6dwq8z --chain-id test-1
+```
+This should return:
+```
+balances:
+- amount: "100000000000000"
+denom: untrn
+pagination:
+total: "1"
+```
+
+Install neutrond locally:
+```
+make install
+```
+
+To setup the local keyring:
+```
+cd docker/neutrond
+make create-local-accounts
+```
+
+Verify local keyring setup:
+```
+neutrond query bank balances neutron1qnk2n4nlkpw9xfqntladh74w6ujtulwn6dwq8z --chain-id test-1
+```
+
+This should return:
+```
+balances:
+- amount: "100000000000000"
+denom: untrn
+pagination:
+total: "1"
+```
+
+To stop and reset the chain, go back into the neutron source folder from github and run:
+```
+make stop-docker-container
+```
+
+## How accounts are setup on neutron
+We use the standard 7 accounts that come from the neutron base docker setup. We have imported those to `docker/neutrond/accounts`. These accounts already exist in the container running the node, and we get them locally by running `make import-local-accounts`. We don't have functions to create or delete accounts, since we want to strictly follow their base docker setup, and thus keep the accounts the exact same. The 7 accounts are:
+- `demowallet1`, `demowallet2` and `demowallet3` - These are the accounts you should use for testing. They are seeded with the test token `untrn`, and 2 IBC tokens, `uibcatom` and `uibcusdc`.
+- `val1` and `val2` - accounts used to setup the validators for the test network. Seeded only with the test token `untrn`. Use if you need extra accounts beyond the demo wallets.
+- `rly1` and `rly2` - accounts used to setup IBC relayers for the test network. Only seeded with `untrn`. Use if you need extra accounts beyond the demo wallets.
