 ## Development Installation
 
+If you don't have direct access to push to mermaid repositories, make a fork first. Then clone. Or clone directly from mermaid-js:
+
 ```bash
 git clone git@github.com:mermaid-js/mermaid.git
 cd mermaid
+```
+
+Install required packages:
+
+```bash
 # npx is required for first install as volta support for pnpm is not added yet.
 npx pnpm install
 pnpm test
 ```
 
+If you are using docker and docker-compose, you have self-documented `run` bash script, which is a convenient alias for docker-compose commands:
+
+```bash
+./run install # npx pnpm install
+./run test # pnpm test
+```
+
 ## Committing code
 
 We make all changes via pull requests. As we have many pull requests from developers new to mermaid, the current approach is to have _knsv, Knut Sveidqvist_ as a main reviewer of changes and merging pull requests. More precisely like this:
