nerimity-sdk 1.4.1

A fully-featured Python SDK for building Nerimity bots

nerimity-sdk

A Python library for building bots on Nerimity. Don't worry if you're new to Python — this guide will walk you through everything step by step! 🐱

---

Before you start — install Python (Windows)

If you've never used Python before, that's totally fine! Here's how to get set up:

1. Go to python.org/downloads and download the latest version
2. Run the installer — make sure to check "Add Python to PATH" before clicking Install
3. Open Command Prompt (press Win + R, type cmd, hit Enter)
4. Type python --version and press Enter — if you see a version number, you're good to go! ✅

---

Install the SDK

Open Command Prompt and run:

pip install nerimity-sdk
pip install nerimity-sdk-contrib

nerimity-sdk-contrib is optional — it adds ready-made plugins like welcome messages, leveling, polls, and more.

---

Get your bot token

1. Go to nerimity.com/app/settings/developer/applications
2. Create a new app → add a Bot → copy the token
3. Keep it secret! Never share your token with anyone 🔒

---

Make your first bot

The easiest way is with the CLI:

nerimity create my-bot
cd my-bot
copy .env.example .env

Open .env in Notepad and paste your token:

NERIMITY_TOKEN=paste_your_token_here

Then run your bot:

python bot.py

That's it! Your bot is online 🎉

---

Or set it up manually

Create a new folder, open it in Command Prompt, and make a file called bot.py:

import os
from dotenv import load_dotenv
from nerimity_sdk import Bot

load_dotenv()
bot = Bot(token=os.environ["NERIMITY_TOKEN"])

@bot.on("ready")
async def on_ready(me):
    print(f"Logged in as {me.username}#{me.tag}")

@bot.command("ping", description="Replies with Pong!")
async def ping(ctx):
    await ctx.reply("Pong! 🏓")

bot.run()

Create a .env file in the same folder:

NERIMITY_TOKEN=paste_your_token_here

Then run:

python bot.py
