+# Getting started
+Before you start, you should understand the concept of forward/up and reverse/down database migrations.
+
+Configure a database for your application. Make sure that your database driver is supported [here](README.md#databases)
+
+## Create migrations
+Create some migrations using migrate CLI. Here is an example:
+```
+migrate create -ext sql -dir db/migrations -seq create_users_table
+```
+Once you create your files, you should fill them.
+
+**IMPORTANT:** In a project developed by more than one person there is a chance of migrations inconsistency - e.g. two developers can create conflicting migrations, and the developer that created his migration later gets it merged to the repository first.
+Developers and Teams should keep an eye on such cases (especially during code review).
+[Here](https://github.com/golang-migrate/migrate/issues/179#issuecomment-475821264) is the issue summary if you would like to read more.
+
+Consider making your migrations idempotent - we can run the same sql code twice in a row with the same result. This makes our migrations more robust. On the other hand, it causes slightly less control over database schema - e.g. let's say you forgot to drop the table in down migration. You run down migration - the table is still there. When you run up migration again - `CREATE TABLE` would return an error, helping you find an issue in down migration, while `CREATE TABLE IF NOT EXISTS` would not. Use those conditions wisely.
+
+In case you would like to run several commands/queries in one migration, you should wrap them in a transaction (if your database supports it).
+This way if one of commands fails, our database will remain unchanged.
+
+## Run migrations
+Run your migrations through the CLI or your app and check if they applied expected changes.
+Just to give you an idea:
+```
+migrate -database YOUR_DATBASE_URL -path PATH_TO_YOUR_MIGRATIONS up
+```
+
+Just add the code to your app and you're ready to go!
+
+Before commiting your migrations you should run your migrations up, down, and then up again to see if migrations are working properly both ways.
+(e.g. if you created a table in a migration but reverse migration did not delete it, you will encounter an error when running the forward migration again)
+It's also worth checking your migrations in a separate, containerized environment. You can find some tools in the end of this document.
+
+**IMPORTANT:** If you would like to run multiple instances of your app on different machines be sure to use a database that supports locking when running migrations. Otherwise you may encounter issues.

+# Getting started
+Before you start, you should understand the concept of forward/up and reverse/down database migrations.
+
+Configure a database for your application. Make sure that your database driver is supported [here](README.md#databases)
+
+## Create migrations
+Create some migrations using migrate CLI. Here is an example:
+```
+migrate create -ext sql -dir db/migrations -seq create_users_table
+```
+Once you create your files, you should fill them.
+
+**IMPORTANT:** In a project developed by more than one person there is a chance of migrations inconsistency - e.g. two developers can create conflicting migrations, and the developer that created his migration later gets it merged to the repository first.
+Developers and Teams should keep an eye on such cases (especially during code review).
+[Here](https://github.com/golang-migrate/migrate/issues/179#issuecomment-475821264) is the issue summary if you would like to read more.
+
+Consider making your migrations idempotent - we can run the same sql code twice in a row with the same result. This makes our migrations more robust. On the other hand, it causes slightly less control over database schema - e.g. let's say you forgot to drop the table in down migration. You run down migration - the table is still there. When you run up migration again - `CREATE TABLE` would return an error, helping you find an issue in down migration, while `CREATE TABLE IF NOT EXISTS` would not. Use those conditions wisely.
+
+In case you would like to run several commands/queries in one migration, you should wrap them in a transaction (if your database supports it).
+This way if one of commands fails, our database will remain unchanged.
+
+## Run migrations
+Run your migrations through the CLI or your app and check if they applied expected changes.
+Just to give you an idea:
+```
+migrate -database YOUR_DATBASE_URL -path PATH_TO_YOUR_MIGRATIONS up
+```
+
+Just add the code to your app and you're ready to go!
+
+Before commiting your migrations you should run your migrations up, down, and then up again to see if migrations are working properly both ways.
+(e.g. if you created a table in a migration but reverse migration did not delete it, you will encounter an error when running the forward migration again)
+It's also worth checking your migrations in a separate, containerized environment. You can find some tools in the end of this document.
+
+**IMPORTANT:** If you would like to run multiple instances of your app on different machines be sure to use a database that supports locking when running migrations. Otherwise you may encounter issues.

+The migration files are permitted to be "empty", in the event that a migration
+is a no-op or is irreversible. It is recommended to still include both migration

+If your database does not support comments, then deleting the migration file will also work.
+Note, an actual empty file (e.g. a 0 byte file) may cause issues with your database since migrate
+will attempt to run an empty query. In this case, deleting the migration file will also work.
