 ## Usage
 
-*Placeholder; Rather than starting to delve into the API docs, it'd be great to see what the client looks like in action in this lang plus a rough description what it does. The dev should be able to quickly determine whether the example fits the desired style and problem.*
+Send requests to a Nimiq node using a `NimiqCommunity\RpcClient\NimiqClient` object.
+
+```php
+$config = [
+    'scheme' => 'http',
+    'host' => '127.0.0.1',
+    'port' => 8648,
+    'user' => 'luna',
+    'password' => 'moon',
+    'timeout' => false,
+];
+
+$client = new \NimiqCommunity\RpcClient\NimiqClient($config);
+```
+
+Once we have the client, we can start communicating with the Nimiq node.
+If no `$config` object is given in constructor it will use same defaults as the Nimiq node defaults.
+
+```php
+$client = new \NimiqCommunity\RpcClient\NimiqClient();
+
+// make rpc call to get the block number
+$blockNumber = $client->getBlockNumber();
+
+echo $blockNumber; // displays the block number, for example 748883
+```
 
 ## API
 
-*Placeholder; All the implemented methods with parameters, types, default values, return types*
+The complete [API documentation](docs) is available in the `/docs` folder.
+
+Check out the [Nimiq RPC specs](https://github.com/nimiq/core-js/wiki/JSON-RPC-API) for behind the scene RPC calls.
 
 ## Installation
 
-*Placeholder; how to add this client to a project. Each language comes with a package manager. To be useful for developers, add a package description file that works with the most commonly used package manager for this language. For example have a `package.json` file for JavaScript or `pom.xml` for Java.*
+The recommended way to install Nimiq PHP Client is with Composer. Composer is a dependency management tool for PHP that
+allows you to declare the dependencies your project needs and installs them into your project.
+
+```sh
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+You can add Nimiq PHP Client as a dependency using the composer.phar CLI:
+
+```sh
+php composer.phar require nimiq-community/php-client
+```
+
+Alternatively, you can specify it as a dependency in your project's existing composer.json file:
+
+```json
+{
+    "require": {
+        "nimiq-community/php-client": "^1.0"
+    }
+}
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+You can find out more on how to install Composer, configure autoloading, and other best-practices for defining dependencies at [getcomposer.org](https://getcomposer.org).
 
 ## Contributions
 
-This implementation was originally contributed by [*Placeholder; Your name with link to GitHub*](https://github.com/nimiq/).
+This implementation was originally contributed by [mariofriz](https://github.com/mariofriz/).
 
 Please send your contributions as pull requests.
 Refer to the [issue tracker](https://github.com/nimiq-community/php-client/issues) for ideas.
 
+### Develop
+
+After cloning the repository, install the dependencies:
+
+```sh
+php composer.phar install
+```
+
+All done, happy coding!
+
+### Testing
+
+Tests are stored in the `/tests` folder and can be run using phpunit:
+
+```sh
+php composer.phar run-script test
+```
+
+To run the tests and generate HTML coverage report:
+
+```sh
+php composer.phar run-script coverage
+```
+
+This will generate the report in `/coverage` folder. [Xdebug](https://xdebug.org/docs/install) is required to generate the coverage report.
+
+### Documentation
+
+The documentation in the `/docs` folder can generated from the source code:
+
+```sh
+php composer.phar run-script docs
+```
+
+It will generate a `README.md` in Github Markdown format.
