+`config.example.yaml`.
+
+```yaml
+# For more information, see the documentation
+# https://kekkai-docs.redume.su/
+
+database:
+    user: 'DATABASE_USERNAME'
+    password: 'DATABASE_PASSWORD'

+
+## Database
+Kekkai is used as a `PostgreSQL` database.
+
+<Aside>
+    If you installed Kekkai via Docker Compose, 
+    then install it in the `database.host` value of `postgres`.
+    The rest of the data does not have to be filled in. 
+    They need to be filled in `.env`.
+
+    What should it look like:
+    ```yaml
+    database:
+        ...
+        host: 'postgres'
+        ...
+    ...
+    ```
+</Aside>
+
+## Server
+<Aside>
+    If you installed Kekkai via Docker Compose, then changing `server.host`, `
+    server.ssl` is not recommended.
+</Aside>
+
+### SSL
+Create a folder CertSSL to store your certificates
+```shell
+mkdir CertSSL
+```
+
+Copy your certificates to the CertSSL folder. 
+
+It is recommended to rename the certificates to `privkey.pem` and `fullchain.pem`. 
+If this is not possible, 
+you need to change the SSL name in `nginx.conf` (if using Docker Compose)
+
+## Analytics
+Kekkai uses [`Plausbile`](https://plausible.io/) as an analyst. 
+Minimal data is transferred for anilithics. 
+Such as: browser, OS, status code, url, where the user came from. 
+Most of the data is built on User Agent. 
+It is possible to disable analytics in Kekkai.
+
+```yaml
+...
+analytics:
+    plausible_api: 'https://plausible.io/api/event/'
+    plausible_domain: 'PLAUSIBLE_DOMAIN'
+    plausible_token: 'PLAUSIBLE_TOKEN'
+    work: true
+...
+```
+
+- `plausible_api`: This is where the Plausible instance is specified. 
+    The official instance is specified by default.
+- `plausible_domain`: Kekkai Instance Domain. 
+  It should be added to Plausible first, and then to the config. 
+  You can add the domain [here](https://plausible.io/sites/new?flow=provisioning).
+- `plausible_token`: Api token for authorization and sending requests. 
+You can create it [here](https://plausible.io/settings/api-keys).
+- `work`: Enable or disable analytics. 
+
+## Currency
+`DuckDuckGo` (fiat currency collection) and `CoinMarketCap` (cryptocurrency collection) 
+are used to collect currency rates.
+
+
+```yaml
+...
+currency:
+    chart:
+        save: false # Enable or disable saving graphs to an image (Boolean)
+    collecting:
+        fiat: true # Turn off or turn on the collection of the fiat currency rate [Boolean]
+        crypto: false
+        schedule: '30 8 * * *' # Currency collection schedule in crontab format [String]
+        crypto_apikey: 'APIKEY'
+    fiat: # List of fiat currency to save the exchange rate [Array]
+        - USD
+        - RUB
+        - EUR
+        - UAH
+        - TRY
+        - KZT
+    crypto:
+        - ETH
+        - TON
+        - USDT
+```
+
+- `currency.chart.save`: Enable or disable saving graphs.
+- `currency.collecting`: Enable or disable cryptocurrency 
+or fiat currency exchange rate collection.
+- `currency.schedule`: Currency collection interval (Configurable via cron. 
+  It is recommended to use [crontab.guru](https://crontab.guru), 
+  not supported in `Non-standard format`, like `@daily`).
+- `crypto.crypto_apiKey`: API-key from CoinMarketCap service
+- `currency.fiat`: A list of fiat currencies that will be saved to the database.
+- `currency.crypto`: A list of crypto currencies that will be saved to the database.
