 PBinCLI is command line client for [PrivateBin](https://github.com/PrivateBin/PrivateBin/) written on Python 3.
 
 Installing
------
+=====
+
+Installation inside `virtualenv`:
 ```bash
-virtualenv --python=python3 venv
+python3 -m virtualenv --python=python3 venv
 . venv/bin/activate
 pip install pbincli
 ```
 
-Usage
------
+Installation to system with pip3:
+```bash
+pip3 install pbincli
+```
+
+*Note: if you used installation with `virtualenv`, don't forget to activate it before usage: call `. /path/to/venv/bin/activate` in terminal*
+
+Configuration
+=====
+
 By default pbincli configured to use `https://paste.i2pd.xyz/` for sending and receiving pastes. No proxy used by default.
 
-You can create config file with variables `server` and `proxy` in `~/.config/pbincli/pbincli.conf` to use different settings.
+You can create config file to use different settings.
 
-Example contents:
+Configuration file is searched in `~/.config/pbincli/pbincli.conf`, `%APPDATA%/pbincli/pbincli.conf` (Windows) and `~/Library/Application Support/pbincli/pbincli.conf` (MacOS)
+
+Example contents
+-----
 
 ```ini
 server=https://paste.i2pd.xyz/
 proxy=http://127.0.0.1:3128
 ```
 
-Run inside `venv` command:
+All possible options for configuration file
+-----
+
+| Option | Default | Possible value |
+|--------|---------|---------|
+server | https://paste.i2pd.xyz/ | Domain ending with slash |
+mirrors | None | Domains separated with comma, like `http://privatebin.ygg/,http://privatebin.i2p/` |
+proxy | None | Proxy address starting with scheme `http://` or `socks5://` |
+short | False | True / False |
+short_api | None | `tinyurl`, `clckru`, `isgd`, `vgd`, `cuttly`, `yourls`, `custom` |

+no_check_certificate | False | True / False |
+no_insecure_warning | False | True / False |
+
+Usage
+=====
 
+Tool available by command `pbincli`, help for every command can be called with `-h` option:
 ```bash
-pbincli send --text "Hello!"
+pbincli {send|get|delete} -h
 ```
 
-Or use stdin input to read text for paste:
+Sending
+-----
 
+* Sending text:
+```bash
+pbincli send -t "Hello! This is test paste!"
+```
+
+* Use stdin input to read text for paste:
 ```bash
 pbincli send - <<EOF
 Hello! This is test paste!
 EOF
 ```
 
-It will send string `Hello! This is test paste!` to PrivateBin.
-
-To send file use `--file` or `-f` with filename. Example:
+* Sending file with text in paste:
+```bash
+pbincli send -f info.pdf -t "I'm sending my document."
+```
 
+* Sending only file without any text:
 ```bash
-pbincli send -c "My document" -f info.pdf
+pbincli send -q -f info.pdf
 ```
 
+__*Note*__: It is possible to set-up paste parameters such as burning after reading, expiritaion time, formatting, enabling discussions, and changing compression algorithm. Please refer to `pbincli send -h` output for more information.
+
+Receiving
+-----
+
 To retrieve paste from server, use `get` command with paste info.
 
-It must be formated like `pasteID#passphrase`. Example:
+It must be formated like `pasteID#Passphrase` or use full URL to paste. Example:
+```bash
+pbincli get xxx#yyy                        ### receive paste xxx from https://paste.i2pd.xyz/ by default
+pbincli get https://example.com/?xxx#yyy   ### receive paste xxx from https://example.com/
+```
+
+Deletion
+-----
 
+To delete paste from server, use `delete` command with required `-p` and `-t` options:
 ```bash
-pbincli get 49eeb1326cfa9491#vfeortoVWaYeJlviDdhxQBtj5e0I2kArpynrtu/tnGs=
+pbincli delete -p xxx -t deletetoken
+```
+
+If you need to delete paste on different server that configured, use `-s` option with instance URL.
+
+Additional examples
+=====
+
+Here you can find additional examples.
+
+Usage with service available inside I2P
+-----
+
+Change settings to use server `http://privatebin.i2p/` and proxy `http://127.0.0.1:4444`. Here's example for configuration file:
+```ini
+server=http://privatebin.i2p/
+proxy=http://127.0.0.1:4444
 ```

+Using tool with aliases
+-----
+
+Example of alias to send paste from `stdin` direclty to I2P service:
 ```bash
-pbincli [-h] {send, get, delete}
+alias pastei2p="echo 'paste the text to stdin' && pbincli send -s http://privatebin.i2p/ -x http://127.0.0.1:4444 -"
