 A friendly PostgreSQL script runner in the spirit of [DbUp](https://github.com/DbUp/DbUp).
 
+[![Build status](https://ci.appveyor.com/api/projects/status/889gkdpvjbjuhkfg?svg=true)](https://ci.appveyor.com/project/datalust/piggy)
+
+### What is Piggy?
+
+Piggy is a simple command-line tool for managing schema and data changes to PostgreSQL databases. Piggy looks for `.sql` files in a directory and applies them to the database in order, using transactions and a change log table to ensure each script runs only once per database.
+
+### Installation
+
+Piggy is available as a Windows MSI installer from [the releases page](https://github.com/datalust/piggy/releases). Linux and macOS are supported, but currently require the `Datalust.Piggy` project in this repository to be built from source.
+
+### Organizing change scripts
+
+Your `.sql` files should be named so that they will sort lexicographically in the order they need to be executed:
+
+```
+001-create-schema.sql
+002-create-users-table.sql
+003-...
+```
+
+If the scripts are arranged in subfolders, these can be ordered as well:
+
+```
+v1/
+  001-create-schema.sql
+  002-create-users-table.sql
+  003-...
+v2/
+  001-rename-users-table.sql
+```
+
+Each script is just regular SQL with any DDL or DML statements required to make a change to the database.
+
+### Applying scripts
+
+Scripts must be applied starting from a _script root_. Piggy searches for `.sql` files and generates script names like `/v1/001-create-schema.sql` using each script's filename relative to the script root. These relative filenames are checked against the change log table to determine which of them need to be run.
+
+The script root is specified with `-s`. Other parameters identify the database server host, the database name, username and password:
+
+```
+piggy apply -s <scripts> -h <host> -d <database> -u <username> -p <password>
+```
+
+If the database does not exist, Piggy will create it using sensible defaults. To opt out of this behavior, add the `--no-create` flag.
+
+For more detailed usage information, run `piggy help apply`; to see all available commands run `piggy help`.
+
+### Transactions
+
+Piggy wraps each script in a transaction that also covers the change log table update. A few DDL statements can't run within a transaction in PostgreSQL - in these cases, add:
+
+```sql
+-- PIGGY NO TRANSACTION
+```
+
+as the first line of the script.
+
+### Variable substitution
+
+Piggy uses `$var$` syntax for replaced variables:
+
+```sql
+create table $schema$.users;
+insert into users (name) values ('$admin$');
+```
+
+Values are inserted using pure text substitution: no escaping or other processing is applied. If no value is supplied for a variable that appears in a script, Piggy will leave the script unchanged (undefined variables will not be replaced with the empty string).
+
+Variables are supplied on the command-line with the `-v` flag:
+
+```
+piggy apply ... -v schema=myapp -v admin=myuser
+```
+
+### Change log
+
+The change log is stored in the target database in `piggy.changes`. The `piggy log` command can be used to view applied change scripts.
