 # TeleTok Telegram Bot
+This bot will monitor any chats for TikTok links that are posted, and then will run the link through a [ProxiTok](https://github.com/pablouser1/ProxiTok) instance to generate a download link. The resulting video file will then get directly uploaded directly to your chat.
 
-This bot is in early development, but the end goal is to have this bot automatically convert all tiktok links in a chat into a videofile that can be re-uploaded to the telegram chat
+## Building
+Requirements: Dotnet SDK 6.0
+
+Run `dotnet build` for a Debug instance
+Run `dotnet publish` for a full release
+
+## Installation
+### Requirements
+ * A telegram bot token
+ * A working [ProxiTok](https://github.com/pablouser1/ProxiTok) instance, either public or hosted yourself. (Please be kind and take bandwidth into account when using a public instance)
+
+### Binary
+ 1. Either build the application or download a release zip for your OS/architecture
+ 2. Edit the config.json and put your telegram bot token in the "token" field, and your chosen ProxiTok instance in the "ptInstance" field
+ 3. Run the TeleTok.exe/TeleTok executable
+
+### Docker
+ 1. You can build an image for yourself with `docker build teletok .` or you can pull a prebuilt image with `docker pull kizaing/teletok:latest`
+ 2. Copy the placeholder config.json from the repo to a location of your choosing
+ 3. Edit the config.json and put your telegram bot token in the "token" field, and your chosen ProxiTok instance in the "ptInstance" field
+ 4. Run the container with `docker run -v ${PWD}/config.json:/app/teletok/config.json -d kizaing/teletok:latest`
+
+
+## To Do
+ - [x] Add better error and link handling
+ - [x] Process videos into telegram
+ - [ ] Add [Matrix](https://matrix.org) support
+ - [ ] Automate binary release publishing
