# Liquidity Provision
### Add Liquildity of Existing Pair
1. Go to Add Liquidity Page
2. Select two tokens that you would like to form pair. The default Price Range is selected for you. If you haven't owned the selected token to your wallet, you will need to register the token to your wallet even if you plan to provide SINGLE token in certain price range.
3. Make sure you select the correct price range. We provide 3 default options but you can work out your own price range. Please note that the default options would maintain 50%:50% values for two tokens(i.e. equal values for two tokens). If you are not using the same ratio for upper bound and lower bound calculation, you may need to input different ratio, e.g. 10k capital -> 7k ETH and 3k USDC.\
Safe: `currentPrice / (1+50%), currentPrice * (1+50%)`\
\
Common: `currentPrice / (1+25%), currentPrice * (1+25%)`\
\
Stable-pair: `currentPrice / (1+1%), currentPrice * (1+1%)`\
\
Full range: `0, Infinity`\

## 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.houstonswap.io/houstonswap/guideline/liquidity-provision.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.
