+Configuration for [Epik](https://www.epik.com/).
+
+
+<!--more-->
+
+- Code: `epik`
+
+Here is an example bash command using the Epik provider:
+
+```bash
+EPIK_SIGNATURE=xxxxxxxxxxxxxxxxxxxxxxxxxx \
+lego --email myemail@example.com --dns epik --domains my.example.org run
+```
+
+
+
+
+## Credentials
+
+| Environment Variable Name | Description |
+|-----------------------|-------------|
+| `EPIK_SIGNATURE` | Epik API signature (https://registrar.epik.com/account/api-settings/) |
+
+The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.
+More information [here](/lego/dns/#configuration-and-credentials).
+
+
+## Additional Configuration
+
+| Environment Variable Name | Description |
+|--------------------------------|-------------|
+| `EPIK_HTTP_TIMEOUT` | API request timeout |
+| `EPIK_POLLING_INTERVAL` | Time between DNS propagation check |
+| `EPIK_PROPAGATION_TIMEOUT` | Maximum waiting time for DNS propagation |
+| `EPIK_TTL` | The TTL of the TXT record used for the DNS challenge |
+
+The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.
