-### Usage
+### Docker-Website usage
 
 There is two ways to download Mangas:
 - Downloading everything and monitor for new Chapters
 - Selecting specific Volumes/Chapters
 
 On the website you add new tasks, by selecting the blue '+' field. Next select the connector/site you want to use, and enter a search term.
-After pressing 'Search', the results will be presented below - this might, depending on the result-size, take a while.
-Next select the publication and a new popup will open with two options:
+After clicking 'Search' (or pressing Enter), the results will be presented below - this might, depending on the result-size, take a while because we are already preloading the cover-images.
+Next select the publication (by selecting the cover) and a new popup will open with two options:
 - "Monitor" - Download all chapters and monitor for new ones
 - "Download Chapter" - Download specific chapters only
 
-When selecting `Monitor` you will be presented with a new window and the selection of the interval you want to check for new chapters.
-When selecting `Download Chapter` a list will open with all available chapters from which you can then select a range.
+When selecting `Monitor` you will be presented with a new window and the selection of the interval you want to check for new chapters (Default: Every 3 hours).
+When selecting `Download Chapter` a list will open with all available chapters - that have not yet been downloaded - from which you can then select a range (see below).
 
 The syntax for selecting chapters is as follows:
 - To download a single Chapter enter either the index number (the number at the very start of the line) or its absolute number like so: `c(h)(apter)[number]`, spaces are allowed.
 - To download a range of chapters enter either a range of index numbers (`3-6`) or chapters (`ch 12-23`).
 - For volumes the syntax is as follows: `v(ol)[number](-[number])`, again spaces allowed.
 
-Examples: `2-12`, `c1`, `ch 2`, `chapter 3`, `v 2`, `vol3-4`, `v2c4` (note: you can only specify a single chapter with this syntax).
+Examples: `2-12`, `c1`, `ch 2`, `chapter 3`, `v 2`, `vol3-4`, `v2c4` (note: you can only specify a single chapter with this last syntax).
