-# 1. Tools
+# 1. How to use
 
-## 1.1. Bandwhich
+Run the build-script `scripts/build.sh` with the path to the tool you want to build.
 
-### 1.1.1. Source
+<br>
+
+The docker-image will be tagged with `default` and the detected version/commit-hash.
+
+You can add more tags or change the existing tag-naming-scheme using the environment-variable `TAG`.
+
+<br>
+
+## 1.1. CLI
+
+`scripts/build.sh <toolPath> [extra-args for docker build ..]`
+
+<br>
+
+### 1.1.1. Example
+`scripts/build.sh tools/bandwhich/`
+
+<br>
+
+### 1.1.2. Environment-Variables
+
+Variable    | Description                       | Default
+-|-|-
+`TAG`       | Tag for Docker-building           | `TAGPREFIX` + `NAME`
+`TAGPREFIX` | Set a prefix to the default-tag   | -
+`NAME`      | Change the name used in the tag   | *FolderName*
+
+<br>
+
+# 2. Tools
+
+## 2.1. Bandwhich
+
+### 2.1.1. Source
 >This is a CLI utility for displaying current network utilization by process, connection and remote IP/hostname
 
 https://github.com/imsnif/bandwhich
 
 <br>
 
-### 1.1.2. Example
+### 2.1.2. Example
 ```
 docker run -it --net host bandwhich -i eth0
 ```
+
+<br>
+
+## 2.2. auto-editor
+
+### 2.2.1. Source
+>Auto-Editor is a command line application for automatically editing video and audio by analyzing a variety of methods, most notably audio loudness.
+
+https://github.com/WyattBlue/auto-editor
+
+<br>
+
+### 2.2.2. Example
+Speed-up silent part of videos:
+```
+docker run -v /home/ruakij/Videos:/video auto-build --no-open --silent-speed 8 --margin 0.2sec "input.webm" -o edited.mp4
+```
+
+<br>
+
+### 2.2.3. Comment
+TODO: Unfortunately the tool requires ffmpeg which is a huge tool and blows up the size of the image. I have to find a way to use a minimized version of it.
+
+<br>
+
+## 2.3. synapse-compress-state
+Includes synapse_auto_compressor
+
+### 2.3.1. Source
+>This workspace contains experimental tools that attempt to reduce the number of rows in the state_groups_state table inside of a Synapse Postgresql database.
+
+https://github.com/matrix-org/rust-synapse-compress-state
+
+<br>
+
+### 2.3.2. Example
+```
+docker run --net container:synapse ghcr.io/ruakij/dockerbuilds/synapse-compress-state:latest synapse_auto_compressor -p postgresql://synapse:synapse@127.0.0.1/synapse -c 500 -n 100
