+# Lightweight, Configurable BASH Eternal History
+
+## Defaults
+
+When this feature is first called, onCreateCommand.sh is created and called in `devcontainer-feature`. 
+This creates and installs a default bash terminal configuration from `feature_settings_rc` which contains opinionated default BASH terminal settings such as:
+* A minimalist, blue bash prompt.
+* Eternal, shared history between containers using this feature.
+
+## Customisation
+
+The user can specify their own terminal preferences in `$CONFIG_STAGING/bashrc`, which defaults to `/devcontainer_staging/bashrc`.
+Then the container is rebuilt, if `bashrc` already exists it won't be overwritten, preserving changes. If the container has been built once already, the existing bashrc must be deleted in order for your changes to be applied. 
+
+
+
+creates staging folder in container 
+creates onCreateCommand.sh in the staging folder
+inputrc and bashrc are also created in the staging folder, containing incremental history searching and user customisations respectively
+feature_settings_rc is created in the staging fodler, which contains a PS1 setup and opinionated terminal features 
+"onCreateCommand" is then exectuted inside the container during finalisation of container setup.
+ - This copies the contents of feature_settings_rc into devcontainer_rc
+ - then copies bashrc and inputrc into the container, unless they exist already to prevent overwriting user edits
+ - then adds root permissions.
+A symbolic link to /root/ is created The items in the CONFIG_FOLDER
+our bashrc is called by /root/.bashrc
