You can use the bot going here: start it, and you can now send it the images you need to convert.

Based on what you send, Stickerify will answer the following:

• the converted image, if you sent a supported file (currently .gif, .gifv and .webp files are not supported)
• an error message, if you sent an unsupported file
• an informative message for any message without a file

1. Chat with Stickers, and use it to create a sticker pack
2. Ask Stickers to add a new sticker
3. Use Stickerify to create the proper file for your sticker
4. Forward Stickerify's message to Stickers
5. Choose an emoji representing your sticker

And it's done!

1. Install Maven and JDK 19 (or higher)
2. Clone the project and move into its folder
3. Run the command ./gradlew build
4. Import the project inside your IDE as a Gradle project
5. Ensure your IDE is correctly configured to use a Java 19 (or higher) JDK

After you successfully set up the project, you will have to go through the following steps:

1. Chat with BotFather and ask it to create a new bot
2. Copy the token it provided you and either:
   • set it as the value of a new environment variable named STICKERIFY_TOKEN
   • use it as the return value of the method getBotToken() inside StickerifyBot
3. Run the Main class to start the bot, it will be now able to answer messages in Telegram

1. Install Docker
2. Prepare the Docker image either:
   • building it passing the token ({{TOKEN}}) retrieved from BotFather with the command:

     docker build -t rob93c/stickerify --build-arg STICKERIFY_TOKEN={{TOKEN}} .

   • pulling the image from Docker Hub:

     docker pull rob93c/stickerify

3. Now you just need to run the Docker image:

   docker run rob93c/stickerify
