+## Linux: `Could not detect a default secure credential storage on your device.`
+
+A possible issue for Electron apps on [Linux](/wiki/linux.md) is the following error.
+
+```sh 
+not detect a default secure credential storage on your device.
+```
+
+This occurs because Electron relies on a Secret Service such as the GNOME Keyring, among others) to
+store passwords securely on the system.
+And often appears on more minimal window managers on [Xorg](/wiki/linux/x_window_system.md) or
+[Wayland](/wiki/linux/wayland.md).
+If no compatible service is running or detected, apps cannot save credentials.
+
+Using the following steps this issue can be solved.
+Firstly - if not already done - install a secret service.
+For the Gnome Keyring install the [packages](/wiki/linux/package_manager.md) `libsecret` and
+`gnome-keyring`.
+The name may differ slightly depending on the [package manager](/wiki/linux/package_manager.md)
+used.
+Afterwards make sure to run the service and enable it if not already done.
+An example for this is shown in the following command
+
+```sh 
+eval $(/usr/bin/gnome-keyring-daemon --start)
+```
+
+Finally the Electron app `<electron-app>` can be started.
+For the secure credential storage to be reachable the environment variable `XDG_CURRENT_DESKTOP`
+has to be set.
+Due to this environment variable being possibly relevant for the system-wide settings it is
+recommended to only set it for the Electron app by running the following command in a sub-shell.
+
+```sh
+export XDG_CURRENT_DESKTOP=GNOME
+<electron-app>

+An example for a system that uses it is
+[Raspberry Pi's AI Hat +](/wiki/linux/raspberry_pi.md#ai-hat).
+
+## Setup
+
+Depending on the system and the type of access various things may have to be setup.
+For Ubuntu systems like the [Raspberry Pi](/wiki/linux/raspberry_pi.md) these are often named
+`hailort-pcie-driver` and `hailort`.
+When using the [Python prorgamming language](/wiki/programming_language/python.md) refer to the
+[Hailo section](/wiki/programming_language/python.md#hailo).
+
+## Usage
+
+This section addresses various usages of the Hailo software.
+
+### Preparing TensorFlow Models for the AI HAT+
+
+For [neural networks](/wiki/neural_network.md) to run on the Hailo AI module and the AI HAT+ they
+have to be converted to the `.hef` format.
+This section assumes the neural network is using
+[TensorFlow](/wiki/programming_language/python.md#tensorflow) and is available as a `.tf` or
+`.tflite` file.
+
+To convert TensorFlow models first the Hailo 8 Software Suite needs to be downloaded.
+This can be done from the [official website](https://hailo.ai/developer-zone/software-downloads/)
+altough an account is needed for it.
+
+After downloading, extracting and then navigating into the folder a heavily customized
+[Docker](/wiki/docker.md) container can be started by running the following command.
+However it is recommended to slightly modify this file.
+Add a volume that contains the TensorFlow model, that is to be converted, to the environment
+variable `DOCKER_ARGS` which is set in the file `hailo_ai_sw_suite_docker_run.sh`.
+
+```sh
+./hailo_ai_sw_suite_docker_run.sh
+```
+
+Using the tools which come in this container a `.tf` or `.tflite` model can be converted to the
+`.hef` format.
+
+For this to work run the following commands inside the Docker container.
+The first command takes the path to the tensorflow model (`<path-to-tf-model>`) and will output a
+`.har` model.
+The second command is optional but recommended and takes the path to this `.har` model
+(`<path-to-har-model`) and returns an optimized `.har` model.
+The third and final command compiles the (optimized) `.har` model, which is given as the input, and
+outputs the final `.hre` model, which then can be used with the Hailo AI module.
+
+```sh
+hailo parser tf <path-to-tf-model>
+hailo optimize --use-random-calib-set <path-to-har-model>
+hailo compiler <path-to-optimized-har-model>
+```
+
+Note that the user in the Docker container usually uses anothr UID and GID.
+To make the volume and files accessible inside the container the IDs of the files in the volume
+should be changed accordingly - for example as shown in the following example.
+`<volume-path>` is the path that points to the volume
+`<uid>` is the UID of the Docker user - which can be found using `id -u` (for example `10642`) -
+and `<gid>` the GID of the Docker user - which can be found using `id -g` (for example `10600`).
+
+```sh
+chown -R <uid>:<gid> <volume-path>
+```
+
+After the models have been converted it can be reversed using the systems user UID and GID.
+
+The converted models can than be run using the Python programming language as described in the
+[Python article](/wiki/programming_language/python.md#hailo).

+# Kiwix
+
+[Kiwix](https://kiwix.org) is a open-source software that allows to save web content like Wikipedia
+or Stack Overflow locally and for offline usage.
+
+## Setup
+
+Kiwix is available for different operating systems and can be installed as described
+[on the official website](https://kiwix.org/en/applications).
+The software can also be setup via [Docker](/wiki/docker.md) with the 
+[kiwix image](/wiki/docker/kiwix_-_kiwix-serve.md).
+
+## Usage
+
+This section addresses the usage of Kiwix.
+
+### Download content
+
+The content to display using Kiwix has to be acquired as a `.zim` file.
+The official collection of these files can be found on the
+[official website](https://library.kiwix.org/).
+For [Docker](/wiki/docker.md) the `.zim` files need to be placed accordingly to the
+[corresponding article](/wiki/docker/kiwix_-_kiwix-serve.md).
+After the downloading the files, Kiwix may have to be restarted.

-#### Preparing TensorFlow Models for the AI HAT+
+### SSH Servera Not Starting for Imager Setups
 
-For neural networks to run on the Hailo AI module and the AI HAT+ they have to be converted to the
-`.hef` format.
-This section assumes the neural network is using
-[TensorFlow](/wiki/programming_language/python.md#tensorflow) and is available as a `.tf` or
-`.tflite` file.
-
-To convert TensorFlow models first the Hailo 8 Software Suite needs to be downloaded.
-This can be done from the [official website](https://hailo.ai/developer-zone/software-downloads/)
-altough an account is needed for it.
-
-After downloading, extracting and then navigating into the folder a heavily customized
-[Docker](/wiki/docker.md) container can be started by running the following command.
-However it is recommended to slightly modify this file.
-Add a volume that contains the TensorFlow model, that is to be converted, to the environment
-variable `DOCKER_ARGS` which is set in the file `hailo_ai_sw_suite_docker_run.sh`.
-
-```sh
-./hailo_ai_sw_suite_docker_run.sh
-```
-
-Using the tools which come in this container a `.tf` or `.tflite` model can be converted to the
-`.hef` format.
-
-For this to work run the following commands inside the Docker container.
-The first command takes the path to the tensorflow model (`<path-to-tf-model>`) and will output a
-`.har` model.
-The second command is optional but recommended and takes the path to this `.har` model
-(`<path-to-har-model`) and returns an optimized `.har` model.
-The third and final command compiles the (optimized) `.har` model, which is given as the input, and
-outputs the final `.hre` model, which then can be used with the Hailo AI module.
-
-```sh 
-hailo parser tf <path-to-tf-model>
-hailo optimize --use-random-calib-set <path-to-har-model>
-hailo compiler <path-to-optimized-har-model>
-```
