-## Database
-Kekkai is used as a `PostgreSQL` database.
-
-!!! info
-    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'
-        ...
-    ...
-    ```
-
-## Server
-!!! info
-    If you installed Kekkai via Docker Compose, then changing `server.host`, `server.ssl` is not recommended.
-
-### 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
-    ...

-        plausible_api: 'https://plausible.io/api/event/'
-        plausible_domain: 'PLAUSIBLE_DOMAIN'

-
-- `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.

-Docker Compose is the recommended method to run Kekkai in production. Below are the steps to deploy Kekkai with Docker Compose.
-
-Kekkai requires Docker Compose version 2.x.
-
-### Steps 1 - Preparing files
-```shell
-git clone https://github.com/Redume/Kekkai.git
-```
-
-```shell
-cd Kekkai
-```
-
-
-### Steps 2 - Change config files
-??? note "Nginx Configuration"
-    In `nginx.conf`, you need to specify your domain or ipv4 address
-    ```
-    ...
-        listen 443 ssl;
-        server_name localhost; # Your domain
-    ...
-    ```
-
-    To set up SSL
-    ```bash
-    mkdir CertSLL
-    ```
-
-    After that, copy the SSL certificates to the `CertSSL` folder, if the names are different, 
-    then change either the name of the certificates or in `nginx.conf`
-
-    ```
-    ssl_certificate /etc/nginx/ssl/fullchain.pem;
-    ssl_certificate_key /etc/nginx/ssl/privkey.pem;
-    ```
-
-??? note "The main config is `config.sample.yaml` for Kekkai"
-    ```yaml
-    database: 
-        user: 'DATABASE_USERNAME'
-        password: 'DATABASE_PASSWORD'
-        host: 'DATABASE_HOST'
-        name: 'DATABASE_NAME'
-        port: 5432
-    ...
-    ```
-
-    Fill in the data in the `database` item, as well as in the `.env` config
-
-
-??? note "`.env.sample` config for PostgreSQL"
-    ```.env
-    # Connection secret for postgres. You should change it to a random password
-    # Please use only the characters `A-Za-z0-9`, without special characters or spaces
-
-    POSTGRES_PASSWORD=my_password
-
-    # If you do not know what you are doing, then you should not edit the values below
-    ###################################################################################
-    POSTGRES_DB=kekkai
-    DB_HOST=postgres
-    POSTGRES_USER=postgres
-    ```
-
-    - Populate custom database information if necessary.
-    - Consider changing `DB_PASSWORD` to a custom value. Postgres is not publically exposed, so this password is only used for - local authentication. To avoid issues with Docker parsing this value, it is best to use only the characters `A-Za-z0-9`.
-
-!!! note 
-    After editing, rename the config files by removing `.sample` in the name
-
-
-### Steps 3 - Start the containers
-```shell title='Start the containers using docker compose command'
-docker compose -f "docker-compose.yaml" up -d --build
-```

-### Steps 4 - Launch Services
-
-Launch each of the services
-There are all three services `MainService`, `Collect-currency`, `Chart`
-
-- `MainService` is an API for getting the exchange rate
-```shell
-cd server & node .
-```
-- `Collect-Currency` is a service for collecting  and save the rate in a database
-```shell
-cd collect-currency/src/ && node .

+## Database
+Kekkai is used as a `PostgreSQL` database.
+
+<Aside>
+    If you installed Kekkai via `Docker Compose`, 
+    set it to `database.host` for postgres. 
+    The password (database.password) should be the same as in `.env`, 
+    the rest of the data doesn't need to be filled in, 
+    it should be in `.env`
+
+    What should it look like:
+    ```hjson
+    database:
+    {
+      ...
+      password: PASSWORD_FROM_ENV
+      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'
+    enabled: 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).
+- `enabled`: Enable or disable analytics. 
+
+## Currency
+`DuckDuckGo` (fiat currency collection) and `CoinMarketCap` (cryptocurrency collection) 
+are used to collect currency rates.
+
+
+```yaml
+...
+    currency:
+    {
+      collecting:
+      {
+        fiat: true
+        crypto: false
+        schedule: 30 8 * * *

+    }
+```
+
+- `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.

+title: Docker

+
+Docker Compose is the recommended method to run Kekkai in production. 
+Below are the steps to deploy Kekkai with Docker Compose.
+
+Kekkai requires Docker Compose version 2.x.
+
+import { Steps, Code } from '@astrojs/starlight/components';
+
+<Steps>
+1. Preparing files
+    ```
+    git clone https://github.com/redume/Kekkai
+    ```
+    ```
+    cd Kekkai
+    ```
+
+2. Change config files
+
+    In nginx.conf, you need to specify your domain or ipv4 address
+    <Code code='
+    ...
+    listen 443 ssl;
+    server_name localhost; # Your domain
+    ...
+    ' lang='txt' title='nginx.conf' />
+
+
+    To set up SSL. Create folder `CertSSL`
+    ```
+    mkdir CertSLL
+    ```
+
+    After that, copy the SSL certificates to the CertSSL folder, 
+    if the names are different, 
+    then change either the name of the certificates or in `nginx.conf`
+
+    <Code code='
+    ssl_certificate /etc/nginx/ssl/fullchain.pem;
+    ssl_certificate_key /etc/nginx/ssl/privkey.pem;
+    ' lang='txt' title='nginx.conf' />
+
+    <Code code=
+    "
+    database: 
+    user: 'DATABASE_USERNAME'
+    password: 'DATABASE_PASSWORD'
+    host: 'DATABASE_HOST'
+    name: 'DATABASE_NAME'
+    port: 5432
+    ...
+    " lang='yaml' title='config.sample.yaml' />
+    Fill in the data in the database item, as well as in the .env config
+
+
+    <Code code='
+    # Connection secret for postgres. You should change it to a random password
+    # Please use only the characters `A-Za-z0-9`, without special characters or spaces
+
+    POSTGRES_PASSWORD=my_password
+
+    # If you do not know what you are doing, then you should not edit the values below
+    ###################################################################################
+    POSTGRES_DB=kekkai
+    DB_HOST=postgres
+    POSTGRES_USER=postgres
+    ' lang='txt' title='.env.sample' />
+
+    - Populate custom database information if necessary.
+    - Consider changing `DB_PASSWORD` to a custom value. 
+    Postgres is not publically exposed, 
+    so this password is only used for - local authentication. 
+    To avoid issues with Docker parsing this value, 
+    it is best to use only the characters `A-Za-z0-9`.
+
+3. Start the containers
+    ```shell
+    docker compose up -d
+    ```
+
+</Steps>
