-## Clicada
-
-> Admin Command Line Interface to interact with cic-meta and cic-cache
-
-### Pre-requisites
-
-- Public key uploaded to `cic-auth-helper`
-- PGP Keyring for your key
-
-### Installation
-
-Use either of the following installation methods:
-
-1. Install from git release (recommended)
-
-```bash
-wget https://git.grassecon.net/grassrootseconomics/clicada/archive/v0.0.6.zip
-unzip clicada-v0.0.6.zip
-cd clicada
-python3 -m venv .venv
-source .venv/bin/activate
-pip install -r requirements.txt --extra-index-url=https://pip.grassrootseconomics.net
-```
-
-2. Install from pip to path (non sudo)
-
-```bash
-pip3 install -UI --extra-index-url=https://pip.grassrootseconomics.net clicada
-```
-
-### GPG Keyring setup
-
-PGP uses the default keyring, you can however pass in a custom keyring path.
-
-To create a keyring from a specific key and get its path for `AUTH_KEYRING_PATH`:
-
-```bash
-# In some dir
-gpg --homedir .gnupg --import private.pgp
-pwd
-```
-
-### Usage
-
-```bash
-usage: clicada [...optional arguments] [...positional arguments]
-
-positional arguments:
-  {user,u,tag,t}
-    user (u)            retrieve transactions for a user
-    tag (t)             locally assign a display value to an identifier
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --no-logs             Turn off all logging
-  -v                    Be verbose
-  -vv                   Be very verbose

-  --dumpconfig {env,ini}
-                        Output configuration and quit. Use with --raw to omit values and output schema only.
-  --env-prefix ENV_PREFIX
-                        environment prefix for variables to overwrite configuration
-  -p P, --rpc-provider P
-                        RPC HTTP(S) provider url
-  --rpc-dialect RPC_DIALECT

-  --height HEIGHT       Block height to execute against
-  -i I, --chain-spec I  Chain specification string
-  -u, --unsafe          Do not verify address checksums
-  --seq                 Use sequential rpc ids
-  -y Y, --key-file Y    Keystore file to use for signing or address
-  --raw                 Do not decode output
-  --fee-price FEE_PRICE
-                        override fee price
