+# celo-indexer
+
+![GitHub Tag](https://img.shields.io/github/v/tag/grassrootseconomics/celo-indexer)
+
+A lightweight Postgres chain indexer designed to couple with [celo-tracker](https://github.com/grassrootseconomics/celo-tracker) to index all relevant GE related blockchain data on the Celo blockchain.
+
+## Getting Started
+
+### Prerequisites
+
+* Git
+* Docker
+* Postgres server
+* Access to a `celo-tracker` instance
+
+See [docker-compose.yaml](dev/docker-compose.yaml) for an example on how to run and deploy a single instance.
+
+### 1. Build the Docker image
+
+We provide pre-built images for `linux/amd64`. See the packages tab on Github.
+
+If you are on any other platform:
+
+```bash
+git clone https://github.com/grassrootseconomics/celo-indexer.git
+cd celo-indexer
+docker buildx build --build-arg BUILD=$(git rev-parse --short HEAD) --tag celo-indexer:$(git rev-parse --short HEAD) --tag celo-indexer:latest .
+docker images
+```
+
+### 2. Run Postgres
+
+For an example, see `dev/docker-compose.postgres.yaml`.
+
+### 3. Update config values
+
+See `.env.example` on how to override default values defined in `config.toml` using env variables. Alternatively, mount your own config.toml either during build time or Docker runtime.
+
+```bash
+# Override only specific config values
+nano .env.example
+mv .env.example .env
+```
+
+Special env variables:
+
+* DEV=*
+
+Refer to [`config.toml`](config.toml) to understand different config value settings.
+
+
+### 4. Run the indexer
+
+```bash
+cd dev
+docker compose up
+```
