+# Chia Healthcheck
+
+Chia Healthcheck is an application that is intended to run alongside a chia installation and return a simple healthy or unhealthy response for supported chia services.
+
+## Installation
+
+Download the correct executable file from the release page and run. If you are on debian/ubuntu, you can install using the apt repo, documented below.
+
+### Apt Repo Installation
+
+#### Set up the repository
+
+1. Update the `apt` package index and install packages to allow apt to use a repository over HTTPS:
+
+```shell
+sudo apt-get update
+
+sudo apt-get install ca-certificates curl gnupg
+```
+
+2. Add Chia's official GPG Key:
+
+```shell
+curl -sL https://repo.chia.net/FD39E6D3.pubkey.asc | sudo gpg --dearmor -o /usr/share/keyrings/chia.gpg
+```
+
+3. Use the following command to set up the stable repository.
+
+```shell
+echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/chia.gpg] https://repo.chia.net/chia-healthcheck/debian/ stable main" | sudo tee /etc/apt/sources.list.d/chia-healthcheck.list > /dev/null
+```
+
+#### Install Chia Healthcheck
+
+1. Update the apt package index and install the latest version of Chia Healthcheck
+
+```shell
+sudo apt-get update
+
+sudo apt-get install chia-healthcheck
+```
+
+## Usage
+
+First, install [chia-blockchain](https://github.com/Chia-Network/chia-blockchain). Chia healthcheck expects to be run on the same machine as the chia blockchain installation, and will use either the default chia config (`~/.chia/mainnet/`) or else the config located at `CHIA_ROOT`, if the environment variable is set.
+
+`chia-healthcheck serve` will start the healthcheck service on the default port of `9915`.
+
+You can check the status of the full node at `<hostname>:9915/full_node`. A response code `200` indicates the full node is receiving new blocks, while a response code of `500` would indicate that a new block has not been received within the healthcheck interval (5 minutes by default).
+
+### Configuration
+
+Configuration options can be passed using command line flags, environment variables, or a configuration file, except for `--config`, which is a CLI flag only. For a complete listing of options, run `chia-healthcheck --help`.
+
+To set a config value as an environment variable, prefix the name with `CHIA_HEALTHCHECK_`, convert all letters to uppercase, and replace any dashes with underscores (`healthcheck-port` becomes `CHIA_HEALTHCHECK_HEALTHCHECK_PORT`).
+
+To use a config file, create a new yaml file and place any configuration options you want to specify in the file. The config file will be loaded by default from `~/.chia-healthcheck.yaml`, but the location can be overridden with the `--config` flag.
+
+```yaml
+healthcheck-port: 9915
+```
