+# Setup MySQL database for PowerDNS-Admin
+
+This guide will show you how to prepare a MySQL or MariaDB database for PowerDNS-Admin.
+
+### Step-by-step instructions
+1. ivan@ubuntu:~$ `mysql -u root -p` (then enter your MySQL/MariaDB root users password)
+2. mysql> `CREATE DATABASE powerdnsadmin CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;`
+3. mysql> `GRANT ALL PRIVILEGES ON powerdnsadmin.* TO 'pdnsadminuser'@'%' IDENTIFIED BY 'p4ssw0rd';`
+4. mysql> `FLUSH PRIVILEGES;`
+5. mysql> `quit`
+
+**NOTE:**
+
+If you plan to manage large zones, you may encounter some issues while applying changes.
+This is due to PowerDNS-Admin trying to insert the entire modified zone into the column history.detail.
+
+Using MySQL/MariaDB, this column is created by default as TEXT and thus limited to 65,535 characters.
+
+_Solution_:
+
+Convert the column to MEDIUMTEXT: 
+
+* `USE powerdnsadmin;`
+* `ALTER TABLE history MODIFY detail MEDIUMTEXT;`

+# Setup Postgres database for PowerDNS-Admin
+
+We assume you already have a postgres database software installed for your platform.
+
+### Create database
+```
+$ sudo su - postgres
+$ createuser powerdnsadmin
+$ createdb powerdnsadmindb
+$ psql
+postgres=# alter user powerdnsadmin with encrypted password 'powerdnsadmin';
+postgres=# grant all privileges on database powerdnsadmindb to powerdnsadmin;
+```
+
+Note:
+- Please change the information above (db, user, password) to fit your setup.
+
+### Setup Remote access to database:
+If your database is on a different server
+
+- You might need to adjust your PostgreSQL's `pg_hba.conf` config file to allow password authentication for networks.
+
+## Docker
+```
+docker run --name pdnsadmin-test -e BIND_ADDRESS=0.0.0.0 
+-e SECRET_KEY='a-very-secret-key' 
+-e PORT='9191' 
+-e SQLA_DB_USER='powerdns_admin_user' 
+-e SQLA_DB_PASSWORD='exceptionallysecure' 
+-e SQLA_DB_HOST='192.168.0.100' 
+-e SQLA_DB_NAME='powerdns_admin_test'
