-Blockchain Rebuilt for Scale
-===
+# Building

-Solana&trade; is a new blockchain architecture built from the ground up for scale. The architecture supports
-up to 710 thousand transactions per second on a gigabit network.

-
-Remote Testnets
---
+### Starting a local testnet
+Start your own testnet locally, instructions are in the [online docs](https://docs.solana.com/bench-tps).

+### Accessing the remote testnet
 * `testnet` - public stable testnet accessible via devnet.solana.com. Runs 24/7

-
-## Deploy process
-
-They are deployed with the `ci/testnet-manager.sh` script through a list of [scheduled
-buildkite jobs](https://buildkite.com/solana-labs/testnet-management/settings/schedules).
-Each testnet can be manually manipulated from buildkite as well.
-
-## How do I reset the testnet?
-Manually trigger the [testnet-management](https://buildkite.com/solana-labs/testnet-management) pipeline
-and when prompted select the desired testnet
-
-## How can I scale the tx generation rate?
-
-Increase the TX rate by increasing the number of cores on the client machine which is running
-`bench-tps` or run multiple clients. Decrease by lowering cores or using the rayon env
-variable `RAYON_NUM_THREADS=<xx>`
-
-## How can I test a change on the testnet?
-
-Currently, a merged PR is the only way to test a change on the testnet.  But you
-can run your own testnet using the scripts in the `net/` directory.
-
-## Adjusting the number of clients or validators on the testnet
-Edit `ci/testnet-manager.sh`
-
-
-## Metrics Server Maintenance
-Sometimes the dashboard becomes unresponsive. This happens due to glitch in the metrics server.
-The current solution is to reset the metrics server. Use the following steps.
-
-1. The server is hosted in a GCP VM instance. Check if the VM instance is down by trying to SSH
- into it from the GCP console. The name of the VM is ```metrics-solana-com```.
-2. If the VM is inaccessible, reset it from the GCP console.
-3. Once VM is up (or, was already up), the metrics services can be restarted from build automation.
-    1. Navigate to https://buildkite.com/solana-labs/metrics-dot-solana-dot-com in your web browser
-    2. Click on ```New Build```
-    3. This will show a pop up dialog. Click on ```options``` drop down.
-    4. Type in ```FORCE_START=true``` in ```Environment Variables``` text box.
-    5. Click ```Create Build```
-    6. This will restart the metrics services, and the dashboards should be accessible afterwards.
-
-## Debugging Testnet
-Testnet may exhibit different symptoms of failures. Primary statistics to check are
-1. Rise in Confirmation Time
-2. Nodes are not voting
-3. Panics, and OOM notifications
-
-Check the following if there are any signs of failure.
-1. Did testnet deployment fail?
-    1. View buildkite logs for the last deployment: https://buildkite.com/solana-labs/testnet-management
-    2. Use the relevant branch
-    3. If the deployment failed, look at the build logs. The build artifacts for each remote node is uploaded.
-       It's a good first step to triage from these logs.
-2. You may have to log into remote node if the deployment succeeded, but something failed during runtime.
-    1. Get the private key for the testnet deployment from ```metrics-solana-com``` GCP instance.
-    2. SSH into ```metrics-solana-com``` using GCP console and do the following.
-    ```bash
-    sudo bash
-    cd ~buildkite-agent/.ssh
-    ls
-    ```
-    3. Copy the relevant private key to your local machine
-    4. Find the public IP address of the AWS instance for the remote node using AWS console
-    5. ```ssh -i <private key file> ubuntu@<ip address of remote node>```
-    6. The logs are in ```~solana\solana``` folder

+hardware at a colocation or office facility.  Also works for vanilla Ubuntu cloud
+instances.
+
+### Pre-Requisites
+
+ - Install Ubuntu 18.04 LTS Server
+ - Log in as a local or remote user with `sudo` privileges
+
+### Install Core Requirements
+
+##### Non-GPU enabled machines
+```bash
+sudo ./setup-new-buildkite-agent/setup-new-machine.sh
+```
+
+##### GPU-enabled machines
+ - 1 or more NVIDIA GPUs should be installed in the machine (tested with 2080Ti)
+```bash
+sudo CUDA=1 ./setup-new-buildkite-agent/setup-new-machine.sh
+```
+
+### Configure Node for Buildkite-agent based CI
+
+- Install `buildkite-agent` and set up it user environment with:
+```bash
+sudo ./setup-new-buildkite-agent/setup-buildkite.sh
+```
+- Copy the pubkey contents from `~buildkite-agent/.ssh/id_ecdsa.pub` and
+add the pubkey as an authorized SSH key on github.
+- Edit `/etc/buildkite-agent/buildkite-agent.cfg` and/or `/etc/systemd/system/buildkite-agent@*` to the desired configuration of the agent(s)
+- Copy `ejson` keys from another CI node at `/opt/ejson/keys/`
+to the same location on the new node.
+- Start the new agent(s) with `sudo systemctl enable --now buildkite-agent`
