+# telegram2md
+
+This script parses output from Telegram channel and converts each post to 
+jekyll-applicable post in markdown.
+
+Telegram Desktop creates JSON file, as well as different directories containing
+multimedia, photos, etc. This script creates new directory and populates it with
+formatted posts ready to publish.
+
+## basic usage
+
+Firstly you need to export your channel history from Telegram Desktop app.
+This could be done from three dots menu. Then popup menu appears, where
+you can choose what data you want to export. The script currently supports
+only photos, voice messages and audio files.
+
+![tg-export](docs/tg-export.png)
+
+In format menu you should specify 'Machine-readable JSON' file and then
+locate to directory of your desire.
+
+To convert your posts to markdown files you need to copy `parse.py` file into
+your export folder and run it there.
+
+```console
+$ cp parse.py /path/to/export/dir
+$ cd /path/to/export/dir
+$ python parse.py
+```
+
+Currently there's no way to change name of ouput folder other than directly
+editing the script. By default it's creating directory `formatted_posts` with
+markdown files in there.
+
+Also if your jekyll directory storing media files in folders other than `photos`
+and `files`, you should change `photo_dir` and `media_dir` variables.
