+# Spotify extension
+
+The Spotify extension for Albert launcher allows you to search
+tracks on Spotify and play them immediately or add them to the
+queue. It also allows you to choose the Spotify client, where
+to play the track.
+
+The extension uses the Spotify Web API.
+
+For the proper
+functionality of extension, **Spotify premium is required**.
+
+![Spotify extension](https://i.imgur.com/CoE2C5i.png)
+
+## Web API connection
+
+### 1. Get your Client ID and Client Secret
+
+Visit: https://developer.spotify.com/dashboard/applications and log
+in with your Spotify account.
+
+Click on the button **Create an app**
+and fill the form. You can use for example name "Albert" and
+description "Spotify extension for Albert launcher".
+
+Once you
+click on **Create**, your new application window will appear. You
+can copy your **Client ID** and show **Client Secret**.
+Both are 32-character strings.
+
+Click on **Edit settings** and add new **Redirect URI**. It doesn't
+have to exist. In this example, I will use: `https://nonexistent-uri.net/`
+
+### 2. Get `code` parameter
+
+Open your browser and visit: https://accounts.spotify.com/cs/authorize?response_type=code&client_id=[[client_id]]&scope=user-modify-playback-state%20user-read-playback-state&redirect_uri=https://nonexistent-uri.net/
+
+You have to replace `[[client_id]]` with your actual **Client ID**.
+
+When you press enter, you will get redirected to
+`https://nonexistent-uri.net/` with `code` in URL parameters.
+Copy that string and note it down for the next usage.
+
+### 3. Get your Refresh Token
+
+I will use `curl` for this last step. Replace or export all variables and run this command:
+
+```
+curl -d client_id=$CLIENT_ID -d client_secret=$CLIENT_SECRET -d grant_type=authorization_code -d code=$CODE -d redirect_uri=https://nonexistent-uri.net/ https://accounts.spotify.com/api/token
+```
+
+Use your Client ID, Client Secret and `code` from the previous step.
+
+It will send POST request and return JSON in the answer.
+You can finally get your **Refresh Token**.
+
+<hr>
+
+The whole process is also similarly described
+[here](https://benwiz.com/blog/create-spotify-refresh-token/).
