 pb is available as a single, self contained binary for Mac, Linux, and Windows. You can download the latest version from the [releases page](https://github.com/parseablehq/pb/releases/latest).
 
-To install pb, download the binary for your platform and place it in your `$PATH`. For example, on Linux:
-
-```bash
-wget https://github.com/parseablehq/pb/releases/download/v0.1.0/pb_linux_amd64 -O pb
-chmod +x pb && mv pb /usr/local/bin

+To install pb, download the binary for your platform, un-tar the binary and place it in your `$PATH`.
 
 ## Usage
 
 pb is configured with `demo` profile as the default. This means you can directly start using pb against the [demo Parseable Server](https://demo.parseable.io). For example, to query:
 
 ```bash
-pb query -i    
+pb query -i
 ```
 
 ### Profiles
 
-To start using pb against your Parseable server, you need to create a profile (a profile is a set of credentials for a Parseable Server instance). You can create a profile using the `pb profile create` command. For example:

 ### Query
 
+Query can be run in plaintext or interactive mode. Plaintext emits simple json data to stdout. Interactive mode opens a TUI based interface to view the data.
+
 #### Plaintext output
 
 By default `pb` sends json data to stdout.
 
 ```bash
-pb query "select * from backend" --from=10m --to=now
+pb query "select * from backend" --from=1m --to=now

+You can use tools like `jq` and `grep` to further process and filter the output. Some examples:

+
+### Live Tail
+
+`pb` can be used to tail live data from Parseable Server. To tail live data, use the `pb tail` command. For example:
 
 ```bash
-pb query "select * from backend" --from=10m --to=now -i
+pb tail backend
 ```
 
+You can also use the terminal tools like `jq` and `grep` to filter and process the tail output. Some examples:
+
+```bash
+pb tail backend | jq '. | select(.method == "PATCH")'
+pb tail backend | grep "POST" | jq .
+```
+
+To stop tailing, press `Ctrl+C`.

 ### Stream Management
 
 Once a profile is configured, you can use pb to query and manage _that_ Parseable Server instance. For example, to list all the streams on the server, run:
