 # anon3anon
 
 Telegram bot for anonymous messages 🎭✨
+
+## Building for local development
+
+Prerequisites:
+
+1. git
+2. docker
+
+Firstly, clone the repository:
+
+```shell
+git clone git@github.com:nightnoryu/anon3anon.git
+```
+
+Then build the binary:
+
+```shell
+./bin/a3abrewkit build
+```
+
+This script will download a [brewkit](https://github.com/ispringtech/brewkit) binary and put it in the `bin` directory of the project.
+
+After that, copy the `docker-compose.override.example.yml` to `docker-compose.override.yml` and set the environment variables:
+
+```yaml
+services:
+  anon3anon:
+    environment:
+      TELEGRAM_BOT_TOKEN: 123:ABC # The token for your bot, obtained from t.me/BotFather
+      OWNER_CHAT_ID: 123 # ID of your chat with your bot
+```
+
+And you're set! Lastly, run the app:
+
+```shell
+./bin/a3acompose up -d
+```
+
+While making changes to the app, don't forget to restart the container:
+
+```shell
+docker restart anon3anon
+```
+
+When you're finished working on the project, bring it down using this command:
+
+```shell
+./bin/a3acompose down
+```
