+## 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
+  -c CONFIG, --config CONFIG

+  -n NAMESPACE, --namespace NAMESPACE
+                        Configuration namespace
+  --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
+                        RPC HTTP(S) backend 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
+  --fee-limit FEE_LIMIT
+                        override fee limit
+
+```
+
+### Example
