# POOL
Pools are the simplest way to earn free tokens on SharDex.\
Stake SDT, earn SDT. **It’s that easy!**
## How to Stake in Pool
**Step 1**
Click **\[Earn]**-**\[POOL]** to enter the pool page.
**Auto SDT** automatically compounds your rewards: any SDT you earn will be harvested and re-invested in the same pool for you.
**Manual SDT** does not automatically compound like Auto SDT. You’ll need to harvest and compound your earnings manually.
**Step 2**
Click **\[Enable]** button, and fill in the amount of SDT you want to stake, or directly stake SDT according to the balance ratio.
Click **\[Confirm]** to confirm staking.
Ratio
**Step3**
You can easily add more SDT to a Pool, or move some SDT to a more profitable pool. Click the **-** to take some SDT out of a pool, or the + to add more to the pool.
***Notes***
*1.Unstaking from the Auto SDT pool has some fee if you unstake within 72 hours.(But now it's still 0%)*
*2.When some pools expire, we will put them in the Finish option.*

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.shardex.org/products/pool.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
