+It is designed to be easy to use and provides a basic set of CA features:
 
 - Create a CA and a self-signed CA certificate
-- Create and sign a few most common types of certificates:
+- Create and sign common types of certificates:
   - Server certificate

   - Email certificate
-- Sign a CSR to create a certificate
 - Revoke a certificate
 - List issued certificates

   paths {
     certificates = "certs"
     private_keys = "private"
+    state_file   = "ca_state.json"

 }
 ```
 
-> **NOTE:** `lab-ca` uses HCL (HashiCorp Configuration Language) for configuration files. You can find more information about HCL [here](https://github.com/hashicorp/hcl).
+- The `ca` block's label is used as a logical name for the CA and for the default state file name.
+- The `paths` block defines where certificates, private keys, and the CA state file are stored.
+- On Linux/macOS, the private keys directory is created with `0700` permissions.
+- The command does not encrypt private keys. Do not use in production.
 
-The `ca` block's label has no function, but may be used to identify the CA in the future.
+---
 
-The following attributes are available:
+### Listing Certificates
 
-- `name` - the name of the CA
-- `country` - the country of the CA
-- `organization` - the organization of the CA
-- `organizational_unit` - the organizational unit of the CA (optional)
-- `locality` - the locality of the CA (optional)
-- `province` - the province of the CA (optional)
-- `email` - the email address of the CA (optional)
-- `key_size` - the size of the CA key in bits (default: 4096)
-- `validity` - the validity period of the CA certificate (default: 10 years)
-- `paths` - paths to store certificates and private keys
+List all issued (non-revoked) certificates:
 
-The `paths` block defines where the command will store the generated certificates and private keys. On Linux and macOS, the directory specified for private keys will be created with `0700` permissions. However, the command does not check if the directory has correct permissions, so you should ensure that the directory is not accessible by other users. On Windows, both directories will be created with the default ACL for the current user. You have to secure the private keys directory yourself.
+```bash
+lab-ca list
+```
 
-> **NOTE:** The command does not encrypt private keys. It is not designed to be used in a production environment.
+To include revoked certificates:
 
-## Certificate Issuance and Provisioning
+```bash
+lab-ca list --revoked
+```
 
-To issue a new certificate, you can use the `issue` command and specify the certificate definition on the command line, or use the `provision` command to provide a file with multiple certificate definitions for batch processing.
+---
 
-The definition file also uses HCL syntax. Here is an example of a certificate definition file:
+### Issuing a Certificate
+
+Issue a new certificate from the command line:
+
+```bash
+lab-ca issue --name <name> [--subject <subject>] [--type <type>] [--validity <period>] [--san <SAN> ...] [--overwrite] [--dry-run] [--verbose]
+```
+
+- `--name` (required): Name for the certificate and key files (used as subject if `--subject` is omitted)
+- `--subject`: Subject Common Name or full DN (optional, defaults to `--name`)
+- `--type`: Certificate type: `client`, `server`, `code-signing`, `email` (comma-separated for multiple usages; default: `server`)
+- `--validity`: Validity period (e.g. `2y`, `6m`, `30d`; default: `1y`)
+- `--san`: Subject Alternative Name (repeatable; e.g. `dns:example.com`, `ip:1.2.3.4`, `email:user@example.com`)
+- `--overwrite`: Allow overwriting existing files
+- `--dry-run`: Validate and show what would be created, but do not write files
+- `--verbose`: Print detailed information
+
+---
+
+### Provisioning Certificates (Batch)
+
+Provision multiple certificates from a batch file (HCL):
+
+```bash
+lab-ca provision --file <certificates.hcl> [--overwrite] [--verbose]
+```
+
+#### Example HCL Provisioning File
 
 ```hcl
 defaults {
-    subject  = "{{ .Name }}.example.org"
-    type     = "server"
+    subject = "{{ .Name }}.example.org"
+    type = "server,client"
     validity = "1y"
-    san      = ["DNS:{{ .Name }}.example.org"]
+    san = ["DNS:{{ .Name }}.example.org"]
 }
 
 variables = {
-    Domain  = "example.net"
+    Domain = "example.net"
     Country = "EX"
 }
 
 certificate "service1" {
     # from default: subject = "{{ .Name }}.example.org"
-    # from default: type = "server"
+    # from default: type = "server,client"
     # from default: validity = "1y"
-    # from default: san = ["DNS:{{ .Name }}.example.org"]
+    # from default: san = ["DNS:service1.example.org"]
 }
 
 certificate "service2" {
-    subject = "{{ .Name }}.example.net"
-    # from default: type = "server"
-    # from default: validity = "1y"
-    san = ["DNS:{{ .Name }}.example.net"]
+    subject = "{{ .Name }}.{{ .Domain }}" # result: service2.example.net
+    san = ["DNS:{{ .Name }}.{{ .Domain }}"] # result: [ "DNS:service2.example.net" ]
 }
 
 certificate "service3" {}
 
-certificate "service4" {
-    subject = "{{ .Name }}.{{ .Domain }}"
-    san     = ["DNS:{{ .Name }}.{{ .Domain }}"]
+certificate "user1" {
+    subject = "CN=User One,emailAddress=user1@example.org,O=Example,C=US"
+    type = "client,email"
+    validity = "1y"
+    san = ["email:user1@example.net"]
 }
 ```
 
-Values specified in the `defaults` block will be used for all certificates unless overridden in individual certificate definitions. Go-style template syntax is also supported, so you can use `{{ .Name }}` to refer to the certificate name, and variables from the `variables` map can be used in templates as well.
+- The `defaults` block provides default values for all certificates unless overridden.
+- The `variables` map can be used in Go template expressions in any field.
+- Each `certificate` block defines a certificate to be issued. The block label is available as `{{ .Name }}` in templates.
+- Fields:
+  - `subject`: Subject string (can be a template)
+  - `type`: Comma-separated usages (server, client, code-signing, email)
+  - `validity`: Validity period (e.g. `1y`, `6m`, `30d`)
+  - `san`: List of SANs (e.g. `DNS:...`, `IP:...`, `email:...`)
 
-You can use DNS or IP SANs for server certificates (`server` and `server-only`), and email SANs for email certificates (`email`). The command will check if the SAN is valid based on the type of certificate.
+---
+
+### Revoking a Certificate
+
+Revoke a certificate by name or serial number:
+
+```bash
+lab-ca revoke --name <name> [--reason <reason>]
+lab-ca revoke --serial <serial> [--reason <reason>]
+```
+
+- `--reason` can be one of: `unspecified`, `keyCompromise`, `caCompromise`, `affiliationChanged`, `superseded`, `cessationOfOperation`, `certificateHold`, `removeFromCRL` (default: `cessationOfOperation`)
+
+---
+
+### Generating a CRL
+
+Generate a Certificate Revocation List (CRL) from revoked certificates:
+
+```bash
+lab-ca crl [--crl-file <path>] [--validity-days <days>]
+```
+
+- `--crl-file`: Output path for CRL file (default: `crl.pem`)
+- `--validity-days`: CRL validity in days (default: 30)
+
+---
+
+### Version
+
+Show version information:
+
+```bash
+lab-ca version
+```
+
+---
+
+## Configuration and Templates
+
+- All configuration and provisioning files use HCL (HashiCorp Configuration Language).
+- Go template syntax is supported in `subject`, `san`, and other string fields. The following variables are available:
+  - `.Name`: The certificate name (from the block label)
+  - Any key from the `variables` map
+
+Example:
+
+```hcl
+subject = "{{ .Name }}.{{ .Domain }}"
+san = ["DNS:{{ .Name }}.{{ .Domain }}"]
+```
+
+## Certificate Types and SANs
+
+- `server`: For server certificates. SANs should be DNS or IP.
+- `client`: For client certificates. SANs can be email or DNS.
+- `email`: For S/MIME/email certificates. SANs should be email.
+- `code-signing`: For code signing certificates.
+
+The tool checks that SANs are valid for the selected certificate type(s). Certificate usage can be combined (e.g. `server,client`).
+
+---
+
+## Example: Real-World Provisioning File
+
+See `examples/example-certificates.hcl` for a more advanced provisioning file with templates and variables.
+
+## Building the Tool
+
+The repository includes a `build.sh` script to build the CLI tool. It updates the version in `version.go` and builds the binary.
+
+To ignore changes made to `version.go` in Git, you can run:
+
+```bash
+git update-index --assume-unchanged version.go
+```
+
+---
+
+## Notes
+
+- The tool does not encrypt private keys. Protect your private keys directory.
+- Not intended for production use.
+- For more information about HCL, see: https://github.com/hashicorp/hcl
