-# YAML/TOML Config
+# Using TOML or YAML Config Files
+
+You can configure Erigon using a YAML or TOML configuration file by specifying its path with the `--config` flag. 
+
+> Note: flags specified in the configuration file can be overridden by directly setting them in the Erigon command line.
+
+Both in YAML and TOML files boolean operators (`false`, `true`) and strings without spaces can be specified without quotes, while strings with spaces must be included in `""` or `''` quotes.
+
+## YAML
+
+Use the `--config` flag to point at the YAML configuration file.
+
+```bash
+./build/bin/erigon --config ./config.yaml --chain=holesky
+```
+
+Example of setting up a YAML config file:
+
+```yaml
+datadir : 'your datadir'
+chain : "mainnet"
+http : true
+http.api : ["eth","debug","net"]
+```
+
+In this case the `--chain` flag in the command line will override the value in the YAML file and Erigon will run on the Holesky testnet.
+
+## TOML
+
+```bash
+./build/bin/erigon --config ./config.toml
+```
+
+Example of setting up TOML config file:
+
+```toml
+datadir = 'your datadir'
+chain = "mainnet"
+http = true
+"http.api" = ["eth","debug","net"]
+```
