+# Channels
+
+This form provides possibility to get channels' posts. Each post includes username, post ID and picture (or thumbnail for video). You can download some count of posts, download all posts till specific date or download posts till specific post ID.
+
+Downloaded post data will be saved in the program cache folder (```Data path```). This cache will be removed after program close.
+
+You can download channels with users you have in the program together.
+
