+We have our own instruction language called heroscript, below you will find details how to use it.
+
+## heroscript
+
+
+Heroscript is our small scripting language which is used for communicating with our digital tools like calendar management.
+
+which has following structure
+
+```heroscript
+
+!!calendar.event_add
+	title: 'go to dentist'
+	start: '2025/03/01'
+	description: '
+		a description can be multiline
+
+		like this
+		'
+
+!!calendar.event_delete
+    title: 'go to dentist'
+
+```
+
+- the format is !!$actor.$action   (there is no space before !!)
+- every parameter comes on next line with spaces in front (4 spaces, always use 4 spaces, dont make variation)
+- every actor.action starts with !!
+	- the first part is the actor e.g. calendar in this case
+	- the 2e part is the action name
+- multilines are supported see the description field
+
+below you will find the instructions for different actors, comments how to use it are behind # which means not part of the the definition itself
+
+## remarks on parameters used
+
+- date
+  - format of the date is yyyy/mm/dd hh:mm:ss
+  - +1h means 1 hour later than now
+  - +1m means 1 min later than now
+  - +1d means 1 day later than now
+  - same for -1h, -1m, -1d
+- money expressed as 
+  - $val $cursymbol
+  - $cursymbol is 3 letters e.g. USD, capital
+- lists are comma separated and '...' around
+
+
+## generic instructions
+
+- do not add information if not specifically asked for
+
+
+## circle
+
+every actor action happens in a circle, a user can ask to switch circles, command available is
+
+```
+!!circle.switch
+	name: 'project x'
+
+```
+
+## calendar
+
+```heroscript
+
+!!calendar.event_add
+	title: 'go to dentist'	
+    start: '2025/03/01'
+	end: '+1h'  #if + notation used is later than the start
+	description: '
+		a description can be multiline
+
+		like this
+		'
+	attendees: 'tim, rob'
+
+!!calendar.event_delete
+    title: 'go to dentist'
+
+```
+
+## NOW DO ONE
+
+schedule event tomorrow 10 am, for 1h, with tim & rob, we want to product management threefold
+now is friday jan 17
+
+only give me the instructions needed, only return the heroscript no text around
+
+if not clear enough ask the user for more info
+
+if not sure do not invent, only give instructions as really asked for

+# HeroLib Docker Environment
+
+This directory contains the Docker configuration and scripts for setting up and managing the HeroLib development environment. The environment includes a containerized setup with VSCode server, SSH access, and PostgreSQL database.
+
+## Key Components
+
+### Docker Configuration Files
+
+- `Dockerfile`: Defines the container image based on Ubuntu 24.04, installing necessary dependencies including:
+  - V language and its analyzer
+  - VSCode server
+  - SSH server
+  - Development tools (curl, tmux, htop, etc.)
+  - HeroLib installation
+
+- `docker-compose.yml`: Orchestrates the multi-container setup with:
+  - PostgreSQL database service
+  - HeroLib development environment
+  - Port mappings for various services
+  - Volume mounting for code persistence
+
+## Scripts
+
+### Container Management
+
+- `shell.sh`: Interactive shell access script that:
+  - Checks if the container is running
+  - Starts the container if it's stopped
+  - Verifies port accessibility (default: 4000)
+  - Provides interactive bash session inside the container
+
+- `debug.sh`: Launches the container in debug mode with:
+  - Interactive terminal
+  - Volume mounts for scripts and code
+  - Port mappings for various services (4000-4379)
+  - Custom entrypoint using ourinit.sh
+
+- `export.sh`: Creates a compressed export of the container:
+  - Stops any running instances
+  - Launches a temporary container
+  - Runs cleanup script
+  - Exports and compresses the container to ~/Downloads/herolib.tar.gz
+
+### SSH Access
+
+- `ssh.sh`: Simple SSH connection script to access the container via port 4022
+
+- `ssh_init.sh`: Configures SSH access by:
+  - Collecting public keys from local ~/.ssh directory
+  - Setting up authorized_keys in the container
+  - Installing and configuring SSH server
+  - Setting appropriate permissions
+  - Enabling root login with key authentication
+
+### Internal Scripts (in scripts/)
+
+- `cleanup.sh`: Comprehensive system cleanup script that:
+  - Removes unused packages and dependencies
+  - Cleans APT cache
+  - Removes old log files
+  - Clears temporary files and caches
+  - Performs system maintenance tasks
+
+- `install_herolib.vsh`: V script for HeroLib installation:
+  - Sets up necessary symlinks
+  - Configures V module structure
+  - Adds useful shell aliases (e.g., vtest)
+
+- `ourinit.sh`: Container initialization script that:
+  - Starts Redis server in daemon mode
+  - Launches VSCode server in a tmux session
+  - Starts SSH service
+  - Provides interactive bash shell
+
+## Port Mappings
+
+- 4000:3000 - Main application port
+- 4022:22 - SSH access
+- 4100:8100 - Additional service port
+- 4101:8101 - Additional service port
+- 4102:8102 - Additional service port
+- 4379:6379 - Redis port
+
+## Usage
+
+1. Build and start the environment:
+   ```bash
+   docker compose up -d
+   ```
+
+2. Access the container shell:
+   ```bash
+   ./shell.sh
+   ```
+
+3. Connect via SSH:
+   ```bash
+   ./ssh.sh
+   ```
+
+4. Debug mode (interactive with direct terminal):
+   ```bash
+   ./debug.sh
+   ```
+
+5. Create container export:
+   ```bash
+   ./export.sh
+   ```
+
+## Development
+
+The environment mounts your local `~/code` directory to `/root/code` inside the container, allowing for seamless development between host and container. The PostgreSQL database persists data using a named volume.
