-# gitea API
+# giteacat
-Testing Gitea Authentication
+This Python script allows sign in to a Gitea instance to all local users of a Mastodon server.
 
 ### Dependencies
 
 -   **Python 3**
--   Gitea running server.
+-   Gitea running server with admin access account
+-   Mastodon's bot account  
+
+## Usage  
+
+From the Mastodon account where this bot is running:  
+
+@bot_username registre  
+
+## Installation  
+
+1. Clone this repo: git clone https://git.mastodont.cat/spla/giteacat.git <target dir>  
+
+2. cd into your <target dir> and create the Python Virtual Environment: `python3.x -m venv .`  
+
+3. Activate the Python Virtual Environment: `source bin/activate`  
+
+4. Run `pip install -r requirements.txt` to install needed libraries.  
+
+5. Run `python setup.py` to setup the Mastodon bot account, bot's access tokens, gitea hostname and gitea access token (admin account).  
+
+6 Use your favourite scheduling method to set `python viquicat.py` to run every minute.
