+## How to setup DB
+
+We are using MariaDB, but any MySQL-compatible database should be enough. There are instructions how to setup it for using with E949.
+
+```bash
+mysql -u root -p
+```
+
+```mysql
+CREATE USER e949@localhost IDENTIFIED BY 'password';
+CREATE DATABASE e949 CHARACTER SET = 'utf8';
+GRANT ALL PRIVILEGES ON e949.* TO e949@localhost;
+FLUSH PRIVILEGES;
+EXIT
+```
+
+```bash
+mysql -u e949 -p
+```
+
+```mysql
+USE e949;
+CREATE TABLE posts (
+	id BIGINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY COMMENT 'Unique identifier of post',
+	author_id BIGINT UNSIGNED NOT NULL COMMENT 'Identifier of post author',
+	comment_section_id BIGINT UNSIGNED NULL COMMENT 'Identifier of post comment section',
+	posted_at TIMESTAMP NOT NULL ON UPDATE CURRENT_TIMESTAMP COMMENT 'When post was published',
+	tags VARCHAR(2048) NOT NULL COMMENT 'Comma-delimited list of post tags',
+	title VARCHAR(8192) NULL COMMENT 'Caption for the post',
+	votes_up INT UNSIGNED NOT NULL DEFAULT 0 COMMENT 'Amount of positive reactions',
+	votes_down INT UNSIGNED NOT NULL DEFAULT 0 COMMENT 'Amount of negative reactions',
+	views BIGINT UNSIGNED NOT NULL DEFAULT 0 COMMENT 'Amount of post views',
