# Configuring instance
You can configure your instance from admin interface. You need account with admin rights and little change in config file, which will allow settings dynamic configuration from database.
```elixir
config :pleroma, :instance,
dynamic_configuration: true
```
## How it works
Settings are stored in database and are applied in `runtime` after each change. Most of the settings take effect immediately, except some, which need instance reboot. These settings are needed in `compile time`, that's why settings are duplicated to the file.
File with duplicated settings is located in `config/{env}.exported_from_db.exs`. For prod env it will be `config/prod.exported_from_db.exs`.
## How to set it up
You need to migrate your existing settings to the database. You can do this with mix task (all config files will remain untouched):
```bash
mix pleroma.config migrate_to_db
```
Now you can change settings in admin interface. After each save, settings are duplicated to the `config/{env}.exported_from_db.exs` file.
<span style="color:red">**ATTENTION**</span>
**<span style="color:red">Be careful while changing the settings. Every inaccurate configuration change can break the federation or the instance load.</span>**
*Compile time settings, which require instance reboot and can break instance loading:*
- all settings inside these keys:
- `:hackney_pools`
- `:chat`
- `Pleroma.Web.Endpoint`
- partially settings inside these keys:
- `:seconds_valid` in `Pleroma.Captcha`
- `:proxy_remote` in `Pleroma.Upload`
- `:upload_limit` in `:instance`
## How to remove it
1. Truncate or delete all values from `config` table
```sql
TRUNCATE TABLE config;
```
2. Delete `config/{env}.exported_from_db.exs`.
For `prod` env:
```bash
cd /opt/pleroma
cp config/prod.exported_from_db.exs config/exported_from_db.back
rm -rf config/prod.exported_from_db.exs
```
*If you don't want to backup settings, you can skip step with `cp` command.*
3. Set dynamic configuration to `false`.
```elixir
config :pleroma, :instance,
dynamic_configuration: false
```
4. Restart pleroma instance
```bash
sudo service pleroma restart
```
