+# Developing Tsuru Plugins
+
+Tsuru plugins are the standard way to extend tsuru-client functionality transparently.
+
+A tsuru-client plugin is any runnable file, located inside `~/.tsuru/plugins` directory.
+It works by finding the runnable file (with or without extension) with that plugin name.
+
+A simple working example:
+```bash
+cat > ~/.tsuru/plugins/myplugin.sh <<"EOF"
+#!/bin/sh
+echo "Hello from tsuru plugin ${TSURU_PLUGIN_NAME}!"
+echo "  called with args: $@"
+EOF
+
+chmod +x ~/.tsuru/plugins/myplugin.sh
+
+tsuru myplugin subcommands -flags
+
+##### printed:
+# Hello from tsuru plugin myplugin!
+#   called with args: subcommands -flags
+```
+
+You may find available tsuru plugins on github, by searching for the topic [`tsuru-plugin`](https://github.com/topics/tsuru-plugin).
+(If you are developing a plugin, please tag your github repo).
+
+## Distributing a tsuru plugin
+
+The best way to distribute a tsuru plugin is making it compatible with `tsuru plugin install`.
+There are different approaches for distributing the plugin,
+depending on the language used for building it.
+
+### script-like single file
+If the plugin is bundled as a **script-like single file** (eg: shell script, python, ruby, etc...)
+you may make it available for download on a public URL.
+The name of the file is irrelevant on this case.
+
+### bundle of multiple files
+If the plugin is bundled as **multiple files**, you should compact them inside a `.tar.gz` or `.zip` file,
+and make it available for download on a public URL.
+In this case, the file entrypoint must has the same name as the plugin (file extension is optional).
+The CLI will call the binary at `~/.tsuru/plugins/myplugin/myplugin[.ext]`.
+
+### compiled binary
+If the plugin is bundled as a **compiled binary**, you should create a `manifest.json` file
+(as defined on issue [#172](https://github.com/tsuru/tsuru-client/issues/172))
+which tells where to download the appropriate binary:
+```json
+{
+  "SchemaVersion": "1.0",
+  "Metadata": {
+    "Name": "<pluginName>",
+    "Version": "<pluginVersion>"
+  },
+  "UrlPerPlatform": {
+    "<os>/<arch>": "<os_arch_url>",
+    ...
+  }
+}
+```
+
+Each supported os/arch (check the latest release), should be compacted as `.tar.gz` or `.zip` file.
+All files (`manifest.json` and all compacted binaries) must available for download on public URLs.
+
+An example of such a plugin, hosted on github, is the
+[`rpaasv2` plugin](https://github.com/tsuru/rpaas-operator/issues/124),
+installed using this [manifest.json](https://github.com/tsuru/rpaas-operator/releases/latest/download/manifest.json).
+
+## Available ENV variables
+
+When a plugin is called, the main tsuru-client passes some additional environment variables:
+
+| env               | description                             |
+| ----------------- | --------------------------------------- |
+| TSURU_TARGET      | tsuru server url (eg: https://tsuru.io) |
+| TSURU_TOKEN       | tsuru authentication token              |
+| TSURU_PLUGIN_NAME | name called from the main tsuru-client  |
