+## Official release
+
+To install LangChain run:
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+import CodeBlock from "@theme/CodeBlock";
+
+<Tabs>
+  <TabItem value="pip" label="Pip" default>
+    <CodeBlock language="bash">pip install langchain</CodeBlock>
+  </TabItem>
+  <TabItem value="conda" label="Conda">
+    <CodeBlock language="bash">conda install langchain -c conda-forge</CodeBlock>
+  </TabItem>
+</Tabs>
+
+This will install the bare minimum requirements of LangChain.
+A lot of the value of LangChain comes when integrating it with various model providers, datastores, etc.
+By default, the dependencies needed to do that are NOT installed.
+However, there are two other ways to install LangChain that do bring in those dependencies.
+
+To install modules needed for the common LLM providers, run:
+
+```bash
+pip install langchain[llms]
+```
+
+To install all modules needed for all integrations, run:
+
+```bash
+pip install langchain[all]
+```
+
+Note that if you are using `zsh`, you'll need to quote square brackets when passing them as an argument to a command, for example:
+
+```bash
+pip install 'langchain[all]'
+```
+
+## From source
+
+If you want to install from source, you can do so by cloning the repo and running:
+
+```bash
+pip install -e .
+```
