-# Hollow Knight Completion Check
+# Hollow Knight: Analyze Save Completion Online Tool
 
-> Tool for checking what is left for full 112% completion percentage in the game Hollow Knight.
+> Analyze your saves. See precisely what you missed and where. See Completion %, locations (also Shards/Fragments), costs. I even designed spoiler-free hints based on your progress, if you are completely lost.
 
 ## General info
 
+Hollow Knight doesn't have a game completion list. There is no way to easily check what specific things someone forgot to do for full 112% Game Completion. So I wrote a tool for that. It can also give an optional hint if stuck, based on the in-game progress.
+
+Inspirations: discussions on the forum, KayDeeTee and bloodorca's Save Editors, programming learning, Elderbug.
+
+If this is your first playthrough and you feel completely lost, I will give you a very slight optional hint which should point you in the right direction (no major spoilers). Hidden by default.
+
+I will show you all individual Mask Shards and Vessel Fragments as well as locations and costs of every item on the list. Locations/costs are hidden by default if you don't want spoilers.
+
+## How to use
+
+* Use bloodorca's amazing [Online Save File Editor](https://bloodorca.github.io/hollow/) to decode your Hollow Knight user*.dat save file into text.
+
+* **CTRL+A** (Select All) inside the text box after decoding the save. **CTRL+C** (Copy) to copy the whole contents inside the text box. Be careful not to copy the whole webpage! Only the text inside the text box.
+
+* **CTRL+V** (Paste) the text data inside the text box on the [Tool's webpage](http://reznortech.rf.gd/hollow-knight-completion/).
+
+* Click **"Analyze Text"**. If the copy-pasted data was correct, you will see your Completion %, Play Time, and a whole list of things you have done (✅) or not yet done (❌).
+
+## Hollow Knight Save game locations
+
+#### Windows
+`%USERPROFILE%\AppData\LocalLow\Team Cherry\Hollow Knight\`
+
+#### Linux
+`~/.config/unity3d/Team Cherry/Hollow Knight/`
+
+#### macOS
+`~/Library/Application Support/unity.Team Cherry.Hollow Knight/`
+
+#### Filenames
+
+**user*.dat** — main save file. Where * is a number between 1 and 4, and it is the appropriate save slot inside the game.
+**user*.dat.bakX** — backup save files. Where X is a number in ascending order meaning how many backups were made during the whole playthrough of that save. The higher the number, the more recent the backup. There are usually 3 save backups at one time, older backups are deleted.
+
+## Support and feedback
+
+All feedback/problems/wrong data are appreciated. Feel free to write them in the [Steam Discussion](https://steamcommunity.com/sharedfiles/filedetails/?id=2209910193) thread for the Tool.
+
+Currently only things that are necessary for Game Completion % achievements are shown. The tool doesn't show all the optional things, bosses, challenges, relics found, geo caches opened etc. that are not required for completion %.
+
