+# PKG Development
+
+This document aims to help you get started with `pkg` developemnt.
+
+## Release Process
+
+In order to create release just run the command:
+
+```bash
+npm run release
+```
+
+This command will start an interactive process that will guide you through the release process using [release-it](https://github.com/release-it/release-it)
+
+## Testing
+
+Before running tests ensure you have build the project by running:
+
+```bash
+npm run build
+```
+
+> [!NOTE]
+> Remember to run again `npm run build` after changing source code (everything inside `lib` folder).
+
+Than you can use the following command to run tests:
+
+```bash
+node test/test.js <target> [no-npm | only-npm | all] [<flavor>]
+```
+
+- `<target>` is the node target the test will use when creating executables, can be `nodeXX` (like `node20`) or `host` (uses host node version as target).
+- `[no-npm | only-npm | all]` to specify which tests to run. `no-npm` will run tests that don't require npm, `only-npm` will run against some specific npm modules, and `all` will run all tests.
+- `<flavor>` to use when you want to run only tests matching a specific pattern. Example: `node test/test.js all test-99-*`. You can also set this by using `FLAVOR` environment variable.
+
+Each test is located inside `test` directory into a dedicated folder named following the pattern `test-XX-*`. The `XX` is a number that represents the order the tests will run.
+
+When running `node test/test.js all`, based on the options, each test will be run consecutively by running `main.js` file inside the test folder.
+
+### Example test
+
+Create a directory named `test-XX-<name>` and inside it create a `main.js` file with the following content:
+
+```javascript
+#!/usr/bin/env node
+
+'use strict';
+
+const assert = require('assert');
+const utils = require('../utils.js');
+
+assert(!module.parent);
+assert(__dirname === process.cwd());
+
+const input = './test-x-index';
+
+const newcomers = [
+  'test-x-index-linux',
+  'test-x-index-macos',
+  'test-x-index-win.exe',
+];
+
+const before = utils.filesBefore(newcomers);
+
+utils.pkg.sync([input], { stdio: 'inherit' });
+
+utils.filesAfter(before, newcomers);
+```
+
+Explaining the code above:
+
+- `assert(!module.parent);` ensures the script is being run directly.
+- `assert(__dirname === process.cwd());` ensures the script is being run from the correct directory.
+- `utils.filesBefore(newcomers);` get current files in the directory.
+- `utils.pkg.sync([input], { stdio: 'inherit' });` runs `pkg` passing input file as only argument.
+- `utils.filesAfter(before, newcomers);` checks if the output files were created correctly and cleans up the directory to the original state.
+
+### Special tests
+
+- `test-79-npm`: It's the only test runned when using `only-npm`. It install and tests all node modules listed inside that dir and verifies if they are working correctly.
+- `test-42-fetch-all`: Foreach known node version verifies there is a patch existing for it using pkg-fetch.
+- `test-46-multi-arch`: Tries to cross-compile a binary for all known architectures.
